Installing xp flash drive error 0x0000007b.
There was already an article on this site where we fought the next Blue Screen of Death in the Windows operating system. Then the system issued . This article will tell us how fix STOP 0xc000000B error, which comes out mainly when trying to boot the operating system or during the installation of Windows.
STOP error 0x0000007B on Windows
The STOP 0x0000007B error most often appears on ). It may also be called "INACCESSIBLE_BOOT_DEVICE". If the Windows operating system starts after this error, it may provide additional information:
Problem Event Name: BlueScreen
BCCode: 7b
Causes of STOP error 0x0000007B
STOP error 0x0000007B is caused by device drivers, most commonly related to hard drives or other storage controllers, but also viruses, data corruption, and sometimes hardware failures.
How to fix STOP 0X0000007B error?
Note: Some of these steps may require you to access Windows Safe Mode. If this is not possible in your case, then skip these steps.
- Restart your computer if you have not already done so. Blue Screen of Death 0x0000007B may be the result of a one-time crash.
- Have you just installed or made changes to the Hard Drive Controller? If this is the case, then there is a high probability that the changes made were the result of an error. Try undoing these changes and reboot. Depending on the changes you make, some solutions to the problem may include:
- Remove or reconfigure the installed hard drive;
- Boot to Last Known Known Configuration to undo changes made to the registry;
- Use the function to undo recent changes;
- Roll back your hard drive drivers to a previous version if you have updated them.
- Make sure the SCSI connection is correct if you are using SCSI hard drives. An incorrect SCSI connection causes STOP error 0x0000007B. Most home computers do not use SCSI drives.
- Make sure the hard drive is installed correctly.
- Make sure the hard drive is configured correctly in the BIOS.
- Check your computer for viruses. Some viruses that infect the Master Boot Record (MBR) or boot sector can cause error 0x0000007B. Before doing this, make sure that your antivirus is updated to the latest version and is configured to scan boot sectors and MBR. Of course, this can be done either by connecting the problematic hard drive to another computer, or by booting from an alternative media with a good antivirus.
- Update the drivers for the hard drive controller. This will help if the drivers are damaged or incorrect. If error 0x0000007B occurs during Windows installation, then load the latest drivers during installation of the operating system. In such a situation, you may receive the STOP code 0xC0000034.
- Change SATA mode in Bios to IDE mode. Disabling advanced SATA drive features in the BIOS may solve the problem, especially if you see it in Windows XP. Depending on your BIOS version, SATA mode may be called AHCI, ATA, Legacy or Compatibility Mode.
- Run CHKDSK to check your hard drive. If the boot volume is damaged, CHKDSK can repair the damage.
- Run the FIXMBR command to create a new master boot record.
- Clearing CMOS.
- BIOS update.
- Reinstalling Windows.
- If none of the steps help, then you need to take the computer for diagnostics.
These are the steps you need to take to solve STOP 0x0000007b.
P.S. Taking into account the fact that Windows error codes sometimes pop up in a variety of situations, I think everyone will be happy if users leave in the comments a description of their situation and the steps taken to correct the errors.
Despite the fact that more than three years have passed since Microsoft stopped supporting Windows XP, some users still do not want to part with this operating system. Well, this is understandable - some still have an old computer, the technical characteristics of which do not allow installing a newer OS, some need a fast system, while others are simply used to XP, not wanting to change anything for themselves.
Windows is a fairly stable and reliable system that can work without reinstallation for up to several years, but sooner or later it begins to fail, including critical ones. An example of one such failure is the Stop 0x0000007b error, which occurs during the loading/installation of the operating system and is accompanied by the appearance of the traditional blue screen of death. Most often, Windows XP users have to deal with it, however, owners of computers running Windows 7 are not immune from it.
The main reasons for the appearance of a blue screen with Stop error 0x0000007b
Error 0x0000007b, like a number of other similar ones, does not indicate a specific source of the problem, and the code itself may indicate various types of problems. In some cases it is accompanied by a message INACCESSIBLE_BOOT_DEVICE, which immediately makes the user suspect that the hard drive is faulty. In fact, this error only means that the boot driver cannot initialize the boot device, that is, the hard drive.
The appearance of a blue screen with error 0x0000007b is often caused by a conflict of drivers of devices connected to the PC, incorrect BIOS settings, damage to system files or important registry keys, virus infection, the presence of bad sectors and file system errors on the disk, various hardware problems (most often associated with disk), problems with RAM, lack of support for the SCSI controller or hard drive installed by the operating system. We will not analyze all cases in detail; instead, we will pay attention to the most common ones.
What to do if an error occurs when installing Windows XP
The main and most likely cause of error 0x0000007b when installing Windows XP on a new PC is incompatible BIOS settings. The fact is that on new computers, the ACHI standard is used for drives connected to SATA, which was not yet used at the time of the release of Windows XP. You try to install the system, but it can't find a suitable driver and throws you into a BSOD. What to do? Try changing the operating mode of SATA drives from AHCI to IDE.
Go to the BIOS, in the Advanced section find the IDE Configuration setting, in it find the SATA Configuration parameter and set it to Compatible instead of Enhanced. In other BIOS versions, the indicated setting may be located in the Integrated Peripherals section and called OnChip SATA Type or SATA RAID/AHCI MODE. Its value needs to be set IDE or Native IDE.
If your BIOS has a Main section, look for SATA Mode in it and set it to IDE Mode.
Loading drivers during XP installation
The next way to resolve the error is to install the missing SCSI or ACHI drivers during the installation of Windows XP, but for this you must already have a floppy disk with drivers that match the configuration of your PC. At the very beginning of the XP installation you need to click F6 to install a special SCSI or RAID driver.
But since this method is hopelessly outdated, there may not be a utility for writing drivers on a disk with Windows XP, just like a floppy drive in your computer. Alternatively, you can use a USB Floppy Drive, but purchasing this device for the sake of installing an outdated system seems impractical.
Integrating SATA AHCI drivers into a Windows XP image
If you consider yourself an advanced user, you can integrate SATA AHCI drivers directly into the Windows XP installation image. For these purposes you will need a utility nLite, original SATA drivers with AHCI support for text mode (downloaded from your motherboard manufacturer’s website) and the Windows XP image itself.
The algorithm of actions is as follows. Unpack the driver archives and the XP ISO image into separate folders.
In the next window, click “Add” and specify the path to the folder with drivers.
Then activate the “Text mode driver” radio button, check the drivers you need and click “OK”, after which the boot image will be recreated.
If error 0x0000007b during system installation was due to driver incompatibility, it will not occur this time.
The method works, but why fool yourself if it is much easier to find on the Internet an image of Windows XP with already integrated AHCI drivers; fortunately, there are more than enough such assemblies created by enthusiasts!
How to fix error 0x0000007b when booting Windows 7
As with XP, incorrect BIOS settings can cause error 0x0000007b to appear when loading Windows 7. The system crash into BSOD with code 0x0000007b was often observed after the user enabled AHCI mode in the BIOS, especially in cases where an SSD drive was installed on the PC. No one argues that AHCI mode has its advantages, but in Windows 7 simply enabling it in the BIOS is not enough; before that, the system must be prepared. Therefore, we restore the previous settings in the BIOS, boot, launch the registry editor with the regedit command and expand this branch:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/msahci
On the right side we find the parameter Start and change its value to 0.
We do the same with the Start parameter in the key HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/iaStorV.
After that, go to the BIOS and enable AHCI. This time the system should boot without error. The next time you reboot the system, the appropriate disk drivers will be installed. At the same time, we also recommend opening Device Manager and checking in the disk properties whether disk write caching is enabled.
Other causes of error 0x0000007b
The following reasons for error 0x0000007b, as well as ways to fix it, are equally applicable to both Windows 7 and Windows XP. If before this the system booted normally, but after updating or installing some driver during the next boot, Windows displayed error 0x0000007b, the reason is probably that the driver is not working properly. First, try booting into the last known known configuration by holding down the key right after turning on the PC. F8 and select the appropriate option.
You can also try booting into safe mode and uninstalling the installed software. If this does not help, you should roll back to a previous restore point if booting into Safe Mode is available. In Windows 7, everything is simpler; in this system you can roll back to a control or full backup copy by booting from the installation disk with the distribution kit.
Disk errors
File system errors and bad sectors can also cause error 0x0000007b. This is where the built-in utility can come to the rescue. chkdsk. Boot the PC from the installation disk (the same XP) by clicking R enter the recovery environment and run the command chkdsk /r.
In Windows 7, the same command is used, but with the /f switch.
If the disk is old and there have been problems with it before, it is recommended that you first connect it to a work computer.
Viruses in the boot sector
It also wouldn't hurt to check the disk for infection with bootkits - viruses that infect the boot sector and MBR record. Naturally, such a check should be done using bootable rescue disks like Dr.Web Сureit. Another option is to remove the disk, connect it to a working PC and run the test from there.
Hardware problems
A blue screen with error 0x0000007b may well be caused by hardware problems. If the problem really is in the hardware, then first of all you need to check the hard drive. The cables (are they connected well) and the power supply are also subject to inspection. Be sure to test your RAM, as there have been cases where error 0x0000007b occurred when RAM modules were damaged.
As additional measures, we can recommend disconnecting all peripheral devices from the PC (to avoid conflicts with their drivers), re-creating the MBR master boot record, updating the hard drive controller drivers, clearing the CMOS, and also replacing the atapi.sys, intelide driver files from under the boot disk .sys, pciide.sys, pciidex.sys from the directory System32/Drivers driver files from a working system of the same version. If you doubt the results of your own actions, it would be wiser to take your computer to a diagnostic center, where specialists will fix the problem.
The operating systems Windows XP and 7, despite the cessation of official support from Microsoft, and a relatively powerful advertising campaign, continue to occupy leading positions in the operating system market. Their reliability has been tested over the years and proven by millions of satisfied users. However, even when using them, errors may occur that prevent full operation.
One of them is error 0x0000007b, as a result of which the so-called blue screen of death appears, the computer does not respond to your actions from the word “at all”. The only way out is to reboot, but even that doesn’t help in such cases. Most often, the problem occurs when reinstalling Windows XP or 7, and manifests itself when the system boots, although this can happen in other situations. It is noteworthy that the situation can repeat itself even on a new computer or laptop.
In this article, we will look at the reasons why error 0x0000007b occurs when installing Windows XP or Windows 7, as well as all the solutions. If you read everything and follow the instructions carefully, you will be able to fix everything without any problems.
In fact, there are quite a few reasons why a blue screen with error stop 0x0000007b occurs. Moreover, they all directly depend on what operation you are performing at that moment. The only thing they have in common is installing Windows XP and running that version or the newer Windows 7. So, what could be causing the problem?
When the system starts:
- Damage to important system files responsible for starting the system.
- Viruses that can penetrate the system very deeply and affect the operation of the system.
- Physical defect of the computer hard drive or errors in its operation.
- A flash drive inserted into the USB connector.
This is what error 0x0000007B looks like
When installing the system:
- Incorrect BIOS settings, which causes a crash.
- Incorrect operation of drivers used in the boot controller. If they are damaged, the controller simply cannot complete the Windows installation procedure to the end.
- There is no support for the hard drive or SCSI controller of the installed operating system. May be on modern models of computers or laptops, since XP is already considered outdated.
Solutions
During system startup
Running the last working configuration
Because the failure can be temporary and random, Windows 7 and XP make it very easy to revert to the last working configuration. What does it mean? During operation, the system copies working files responsible for starting the system and its full operation to a special partition on the hard drive. Also, from time to time, an image of the operating state of the system is created, in which everything works as expected. Several such images are stored on the hard drive. Each time you start your computer, the system automatically selects the most recent one and over time, older settings are deleted. So if you get error 0x0000007b on startup, try opening the last working setup.
To do this, while starting the operating system, press the F8 button to exit to the boot menu. In order to launch this mode for sure, and not miss the moment, press the button several times. You will see a list of boot options: Safe Mode, Boot Logging, Debug Mode, and others. You need to select "Last Known Good Configuration (Advanced)". If everything goes well, Windows will begin loading normally. If this does not happen, this method will not help you, so try one of the following.
Select "Last Known Good Configuration (Advanced)"
Checking the disk for errors
The hard drive is not the most reliable component of your computer, especially if it is not solid state. It has moving mechanisms and consists of a magnetic surface and a read head. If you use a laptop and often work on it while on the go, perhaps even in transport, some sectors of the hard drive may be damaged. If the sector on which the system files necessary for Windows 7 or XP are written is damaged, startup will be impossible. To make sure whether your hard drive is operating with errors or some other reason is possible, you will need to use a proprietary hard drive check utility. But how to open it if Windows does not start?
Usually such a check is quite enough to restore functionality. If the disk is damaged so badly that the standard Windows tool cannot cope with the problem, try using specialized software for resuscitating hard drives. If no problems were found, but error 0x0000007b persists, try the next method.
Virus check
Some malicious files are so insidious and dangerous that they penetrate deep into the Windows system partition and damage system-critical components, resulting in error 0x0000007b. If the previous two methods did not help you, try checking for viruses by booting your computer in safe mode. Here are the step-by-step steps you need to follow to do this:
When installing Windows XP
Incorrect BIOS settings
The most common reason why error 0x0000007b may bother you when installing Windows XP is that the hard drive operating mode is incorrectly set. The fact is that all modern ones are connected via the SATA interface, which ensures reliability and high data transfer speed, and uses the modern ACHI standard, which allows you to use all the capabilities of SATA. Windows XP itself does not support this standard, since it did not yet exist in those days. Accordingly, because of this incompatibility, error 0x0000007b occurs when installing Windows XP and a blue screen appears.
To restore functionality, in the BIOS settings, set the default IDE mode, which will work in SATA compatibility mode. Where is this settings item located? How to set the required parameter?
- Turn on your computer and go to BIOS. Depending on the manufacturer of the laptop or motherboard of the system unit, the keys or combinations thereof that must be pressed to enter the BIOS may differ. Most often this is F2, Del, Esc.
- Depending on the type of BIOS used, the menu layout may differ slightly. Here's what you might need to click:
- Main menu - Advanced - OnChip SATA Type - Native IDE - F10 to save settings.
- Main menu - Advanced - IDE Configuration - Compatible - F10 to save settings.
- Main menu - Main - SATA Mode - IDE Mode - F10 to save settings.
- After activating the mode, repeat the installation of Windows XP.
No controller driver
Windows XP is known for its builds from various programmers, who either cut out some components to make the image easier and allow it to work even on old and very weak systems, or integrate additional software. When using trimmed assemblies, you can very often encounter the fact that they lack the necessary controller driver, which causes the XP installation to be interrupted and a blue screen to appear with an error.
The only correct solution would be to download another operating system image with a built-in driver. To do this, you can look for another assembly on torrent trackers and carefully read the description.
Conclusion
Now you know how to deal with error 0x0000007b when installing or starting Windows 7 or Windows XP. We have described the most common causes of its occurrence, as well as the most effective methods for solving it. If nothing helps anyway, the blue screen continues to pop up, then you should think about buying a new computer or laptop, or simply completely reinstall the system, download a clean and original image. In the comments, please indicate whether you managed to get rid of the problem using our recommendations.
Installing Windows XP on modern hardware often poses some problems. During installation, various errors and even BSODs (blue screens of death) appear. This is due to the old operating system being incompatible with the hardware or its features. One of these errors is BSOD 0x0000007b.
A blue screen with this code may be caused by the lack of a built-in AHCI SATA controller driver, which allows you to use various functions for modern drives, including. If your motherboard uses this mode, then Windows XP will not be able to install. Let's look at two methods for eliminating the error and look at two separate special cases with Intel and AMD chipsets.
Method 1: BIOS setup
Most motherboards have two operating modes for SATA drives – AHCI and IDE. For a normal installation of Windows XP, you must enable the second mode. This is done in the BIOS. You can enter the motherboard settings by pressing the key several times DELETE at boot (AMI) or F8(Award). In your case, it may be a different key; you can find out by reading the manual for the motherboard.
The parameter we need is mainly located on the tab with the name "Main" and is called "SATA Configuration". Here you need to change the value from "AHCI" on "IDE", press F10 to save the settings and reboot the machine.
After these steps, Windows XP will most likely install normally.
Method 2: Adding AHCI Drivers to the Distribution
If the first option does not work or there is no option to switch SATA modes in the BIOS settings, you will have to manually integrate the necessary driver into the XP distribution. To do this, we will use the nLite program.
- Go to the official website of the program and download the installer. We download exactly the one highlighted in the screenshot, it is intended for XP distributions.
If you are going to integrate, working directly in Windows XP, then you must also install 2.0 from the official website of the developer. Pay attention to the bit depth of your OS.
- Installing the program will not cause any difficulties even for a beginner, just follow the Wizard’s prompts.
- Next, we will need a compatible driver package, for which we need to find out which chipset is installed on our motherboard. This can be done using the program. Here in the section "Motherboard", on the tab "Chipset" the necessary information is found.
- Now let's go to the page that contains packages that are perfect for integration using nLite. On this page we select the manufacturer of our chipset.
Download the package.
- The archive that we received during downloading must be unpacked into a separate folder. In this folder we see another archive, files from which also need to be extracted.
- Next, you need to copy all the files from the installation disk or image to another folder (new).
- Preparation is complete, launch the nLite program, select the language and click "Further".
- In the next window click "Review" and select the folder into which you copied files from the disk.
- The program will check and we will see data about the operating system, after which we click "Further".
- We simply skip the next window.
- The next step is to select tasks. We need to integrate the drivers and create a boot image. Click on the corresponding buttons.
- In the driver selection window, click "Add".
- Select an item "Drivers folder".
- Select the folder into which we unpacked the downloaded archive.
- We select the driver version of the required bit depth (for the system we are going to install).
- In the driver integration settings window, select all the items (click on the first one, hold down SHIFT and click on the last one). We do this in order to be sure that the required driver is present in the distribution.
- In the next window, click "Further".
- We are starting the integration process.
- Select a mode "Create image", click "Create ISO", select the place where you want to save the created image, give it a name and click "Save".
- The image is ready, exit the program.
The resulting file in ISO format must be written to a USB flash drive and you can install Windows XP.
Above we looked at the option with the Intel chipset. For AMD the process is slightly different.
Conclusion
We have discussed two ways to resolve error 0x0000007b when installing Windows XP. The second one may seem complicated, but using these steps you can create your own distributions for installation on different hardware.
The appearance of a blue screen, designated as BSoD, almost causes a real shock for users. However, in most cases, you can get rid of the problem using several simple methods. But first you need to look at the special stop code in the description. Let's consider the problem of the appearance of BSoD with the STOP code: 0x0000007b (Windows 7) when the system boots. Sometimes the description may also contain the line INACCESSIBLE_BOOT_DEVICE (for systems above version seven).
Error 0x0000007b when loading Windows 7: what is the problem?
The nature of this failure can be determined not only by the stop code, but also by the extended description of the problem presented above. Even if you simply translate the phrase into Russian, it will immediately become clear that the link points to an inaccessible boot device.
Thus, when loading Windows 7, a blue screen (0x0000007b) indicates that there is some problem with the hard drive, or more precisely, with the boot record, which the system cannot access. However, this is only the general case. As practice shows, the problem can be, strange as it may sound, even in an ordinary USB flash drive, which is in the port at the time of boot. In addition, the root causes of failure 0x0000007b Windows 7 when loading the system can be called an incorrectly set operating mode of the hard disk controller, the absence or failure of special drivers, damage to the boot record due to viruses, etc. Based on the above reasons, in each specific case you will have to take appropriate measures. Let's consider the order of actions that it is advisable to perform exactly in the sequence in which they will be described.
Windows 7 crash 0x0000007b on boot: how to fix it, what to do first?
It is possible that the blue screen is due to some kind of short-term failure, such as a sudden power outage when the user does not have an uninterruptible power supply. In this case, you should simply try to restart the computer (maybe even with a preliminary forced shutdown). In this case, it is advisable to completely disconnect all existing peripheral devices and connected drives from the system unit.
During a restart, an automatic system recovery may follow if the failure was indeed short-lived, after which everything will return to normal.
Using special boot options
If Windows 7 failure 0x0000007b appears again during boot, you should restart again, and then quickly press the F8 key several times before the operating system starts loading.
A menu of special start options will appear. First of all, you need to select the start line of the last working configuration. In essence, this is the same restoration or rollback of the system to a previous stable state, when failures and errors were not observed.
Safe mode
In some cases, to resolve Windows 7 crash 0x0000007b at boot, you can use Safe Mode, which can be selected from the menu described for the previous case.
If the system boots normally, the first thing you should do is check it for viruses. To do this, it is best to use portable anti-virus programs, and if necessary, use “heavy artillery” in the form of disk utilities with the general name Rescue Disk, from which you will need to download a virus scanner even before starting the operating system itself, having previously set the appropriate boot priority in the BIOS settings .
Disk check
If the problem reappears in the form of Windows 7 failure 0x0000007b upon boot, you may need to check the disk using the command line. If the system boots at least in safe mode, the command console is called by the standard method using the cmd combination in the Run menu.
If it is impossible to boot, you will have to use any boot or installation disk (or flash drive), in the menu of which you select system recovery, and then call the command line (either from the appropriate section, or by pressing Shift + F10).
In the console you need to enter the check command chkdsk /f/r (sometimes you can use chkdsk /p/r), the execution of which will lead to a full scan of the hard drive with restoration of damaged sectors. When booting from removable media, you must additionally enter the letter of the system partition.
Recovering system files and boot sector
If checking the hard drive does not give results, you will have to use a more complex method. There are two options here: restoring system files and restoring (or completely overwriting) a bootloader that cannot be accessed. But, again, for both methods you will need to make a command line call, as shown above.
In the first case, enter the command sfc /scannow in the console. The process of completing it can be quite long, so you will have to wait.
In the second case, several commands are entered. The first is Bootrec.exe /FixMbr. The second is Bootrec.exe /FixBoot. Once they are completed, you need to exit the Shell and check the system boot. If the result is the same, the console is called again, but the third command to completely rewrite the bootloader is written in it - Bootrec.exe / RebuildBcd. If the failure concerned the boot record, this will give the result in one hundred percent of cases out of a hundred.
BIOS Settings
But the problem may also come from another area. This applies to specialized operating modes of hard disk controllers, the settings of which are located in the primary BIOS input/output system.
When rebooting, you should enter the BIOS and find there something like SATA Mode or SATA Type (the names of the lines, as well as the sections in which they are located, may differ in different BIOS versions). In the settings of the controllers themselves, if the AHCI mode is set, you need to switch it to IDE, then save the settings (F10 + Y), and then reboot.
Hardware and driver problems
It is not uncommon to experience Windows 7 crash 0x0000007b when booting after replacing the motherboard or other hardware. In this case, the user is faced with a situation where the installed motherboard model is not supported by this OS, which causes conflicts, or the system does not recognize it. In this case, the solution will be much more complicated, but if you have an installation disk with drivers, you will only need to install the motherboard chipset drivers yourself or tell the system to select from removable media rather than from its database when installing the driver.
The same, by the way, can also apply to hard drives when special AHCI or SCSI drivers are missing or installed incorrectly. They will also have to be integrated into the system.
If none of the above helps, you may have to reinstall the system with a complete formatting of the system partition, and if the hard drive is physically damaged, replace it. As a last resort, if it is not possible to purchase a new hard drive, you can try to use the HDD Regenerator software package, but this requires that the system boot in at least some mode.
Additional options
As an undocumented method that is used very infrequently, you can use resetting the CMOS settings by first removing the battery on the motherboard for 10-15 minutes. Sometimes it may be necessary to install new BIOS firmware. It is also advisable to check the correct connection of the cables and connectors of the hard drive itself and their integrity. For more serious problems, the computer will have to be taken to a service center for a full diagnosis.
