1. Boot into Windows Recovery Environment (WinRE)
- Interrupt the startup 3 times to enter WinRE.
- Navigate to Troubleshoot → Advanced options for recovery tools.
2. Repair Boot Configuration
- Open Command Prompt in WinRE.
- Run:
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd
- Restart to check if Windows can boot.
3. Run CHKDSK for Disk Errors
- In Command Prompt, type:
- chkdsk C: /f /r /x
- Restart to repair disk corruption.
4. Update or Reinstall Storage Drivers
- Boot into Safe Mode with Networking.
- Open Device Manager → Storage controllers.
- Update drivers or uninstall and reinstall them.
5. Reset BIOS/UEFI Settings
- Enter BIOS/UEFI during startup (Del, F2, Esc).
- Restore Default Settings.
- Ensure boot mode matches disk configuration (AHCI/IDE/UEFI).
6. Restore System Files (SFC & DISM)
- Open Command Prompt (Admin).
- Run:
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
DISM /Image:C:\ /Cleanup-Image /RestoreHealth
- Repairs system files that affect boot access.
7. Perform System Restore
- Go to WinRE → System Restore.
- Select a restore point before the BSOD occurs.
8. Replace or Reconnect Faulty Hardware
- Check hard drives and SSDs for physical damage.
- Reseat SATA/SSD cables.
- Replace failing drives if necessary.
9. Clean Windows Installation (Last Resort)
- Backup your data.
- Perform a clean installation to restore boot access and system integrity.
The 0x0000007B (INACCESSIBLE_BOOT_DEVICE) BSOD signals that Windows cannot access the system partition, often due to boot corruption, storage driver issues, or disk errors.
To fix the issue:
- Repair boot configuration and system files
- Check and update storage drivers
- Reset BIOS/UEFI and reconnect hardware
- Scan disks for errors and restore the system if needed
If unresolved:
- Replace failing drives or storage controllers
- Ensure correct BIOS/UEFI boot mode
- Perform a clean Windows installation for long-term stability
Prompt troubleshooting prevents repeated boot failures, safeguards data, and restores reliable system access.
