Why the error 0x0000007b appears?
Very often, error 0x0000007b
appears in Windows XP when installing the operating system (OS). The causes can be:
1.- The connection to SATA configured incorrectly.
2.- Important drivers are missing in the installation files.
3.- Data corruption when creating boot devices.
The consequence of these reasons
is the appearance of error 0x0000007b when starting the computer with the operating system just installed. But often there are cases when a problem manifests itself due to another cause:
1.- Have a mechanical damage to the hard disk.
2.- The presence of bad sectors.
3.- Incorrect operation of the system registry.
4.- Change the BIOS settings.
5.- Have damage to the boot sector.
6.- Lack of drivers to start up.
What is error 0x0000007b and how to fix it?
The blue screen with STOP 0x0000007b error in Windows XP at boot is removed by modifying BIOS settings or adding prerequisites to the installation image. Also, in the second case, the operation can be performed directly at the time of installation or in advance using special software.
A.- IDE mode configuration in BIOS
At the time of the Windows XP release, the IDE standard was used to determine connected drives, which is considered obsolete. Modern computers use ACHI settings by default. Because of this, the installer cannot read files from the device, resulting in an error.
To fix the problem, you will need to manually change the parameters in the BIOS, for this you need:
A.1.- When the computer starts up, press Del, F2, Esc → F10, depending on the motherboard manufacturer or laptop model, to access the BIOS.
A.2.- Once in the entry and exit utility, go to the Advanced section.
A.3.- Change the SATA Configuration parameter to Compatible.
After changing the parameter, you must save the changes. To do this, you need to press the F10 key and confirm the action in the dialog box. After following the instructions, you can restart your computer and start running the operating system installer.
Important Note.- The names of the sections and the parameters may differ depending on the BIOS version. So, advanced will be called Integrated Peripherals or Main, and SATA Configuration - OnChip SATA Type, SATA RAID / AHCI Mode, or SATA Mode.
B.- Load drivers during installation
Before performing the operation, the Windows XP installer offers to load the necessary drivers to successfully complete the task. This requires a floppy drive and the corresponding utility written on the floppy. Windows XP cannot work with modern USB drives and CD / DVD drives.
If the necessary components are present in the complete set of the computer, then to fix the error 0x0000007b, you will need:
B.1.- Insert the floppy disk into the drive.
B.2.- Start the computer from the installation unit.
B.3.- At the beginning of the installation, press the F6 key.
B.4.- Wait until the process of reading and decompressing the necessary files is completed.
Upon completion, the installer will continue to work automatically and you will be prompted to proceed to the next step.
C.- Add drivers to installation
If necessary, you can embed the missing drivers directly into the operating system installation image. This will require three components:
C.1.- NLite Utility.
C.2.- SATA controller with AHCI support.
C.3.- Image of Windows XP.
NLite Utility NTLite is a tool that allows us to create personalized and unattended Windows installation discs so that each user, without too much technical knowledge, can create their own versions of the operating system in terms of programs, drivers and settings.
To use this tool, the first thing we must do is download it from its main website and install it on our system. NTLite is a free application although it has a paid version with some additional features.
The installation is quick and clean, we can even choose if we want the program to be installed "portable". Once installed we execute it and we will see a window similar to the following one.
TO DOWNLOAD NLite Utility
For integration with NLite you will need:
1.- Unpack the driver and the operating system image.
2.- Start nLite and specify the path to the directory with the Windows XP files.
3.- In the "Integrate" block, select the "Drivers" option and in "Create" - "Bootable ISO image".
4.- In the "Mode" drop-down list, specify Create image.
5.- Select Overview, in the file manager window, select the folder to create an image of the modified system.
6.- Wait until the ISO file is created.
In the future, the image should be written to a USB flash drive through which to install Windows XP.
Windows XP startup troubleshooting?

B.5.- Change the value of the parameter of the same name in the same way.
After completing the steps, you need to restart the computer, enter the BIOS, and change the SATA connection mode as described above.
C.- Reset BIOS settings
The appearance of the error 0x0000007b, can be affected by an incorrect configuration of the parameters of the input and output utility. It is required to replace the configuration of the GOD to the standard one. (Each version of BIOS has its own unique interface, so the instructions may differ.)
Step-by-step guide to change:
