What is 0x0000007b?
0x0000007B: INACCESSIBLE_BOOT_DEVICE
The stop error 0x0000007B, also known as INACCESSIBLE_BOOT_DEVICE, is a common Blue Screen of Death (BSOD) error in Windows operating systems. It indicates that the Windows operating system has lost access to the system partition during startup. This means that Windows cannot find the hard drive or other storage device it needs to boot from.
Common Causes:
- Boot Device Issues: This is the most frequent cause. Potential problems include:
- Faulty or loose data cables connecting the hard drive to the motherboard (e.g., SATA or IDE cables).
- Damaged or failing hard drive.
- Incorrect BIOS settings related to the boot device.
- Driver Issues: Incorrect, outdated, or corrupted storage controller drivers can prevent Windows from accessing the boot device. This often happens after major hardware or software changes. The <a href="https://www.wikiwhat.page/kavramlar/Driver%20Issues" >Driver Issues</a> are often the reason behind this error.
- File System Corruption: Damage to the <a href="https://www.wikiwhat.page/kavramlar/File%20System" >File System</a> on the boot partition can also trigger this error.
- Hardware Incompatibility: A newly installed hard drive or storage controller might not be fully compatible with the system.
- Virus Infection: Rarely, a virus can corrupt the boot sector or critical system files, leading to this error.
- BIOS Issues: Problems with the <a href="https://www.wikiwhat.page/kavramlar/BIOS" >BIOS</a> configuration or firmware can sometimes cause this error.
- Storage Controller Problems: A failing or misconfigured storage controller can block access to the boot device.
Troubleshooting Steps:
- Check Hardware Connections: Ensure that all data and power cables connected to the hard drive are securely fastened.
- Verify BIOS Settings: Access the BIOS setup and confirm that the boot order is correctly configured and that the hard drive is detected. Make sure the storage controller mode (e.g., IDE, AHCI, RAID) is set appropriately.
- Boot into Safe Mode: Try booting into Safe Mode. If you can boot into Safe Mode, it suggests a driver or software issue.
- Update or Roll Back Drivers: If you suspect a driver issue, try updating or rolling back the storage controller drivers. You might need to boot from a Windows installation disc or recovery media to do this.
- Run CHKDSK: Boot from a recovery environment and run the
CHKDSK /f /r command to check and repair file system errors.
- System Restore: If you've recently made changes to your system, try performing a System Restore to revert to a previous state.
- Hardware Diagnostics: Run hardware diagnostics to check the health of your hard drive and other components.
- Reinstall Windows: As a last resort, you may need to reinstall Windows. This will erase all data on the boot partition, so back up any important files first if possible.
- Check the <a href="https://www.wikiwhat.page/kavramlar/Boot%20Order" >Boot Order</a> in BIOS.
