    That error indicates either your PC cannot find the boot drive or the Windows boot configuration is corrupt.

    Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down

    Do this twice

    On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt... etc.

    Please try each option one at a time, then see if Windows will boot up correctly.

    1

    Go to Troubleshoot - Advanced Option - Command Prompt

    Run this command and press Enter.

    bootrec /FixMbr

    Run this command and press Enter.

    bootrec /FixBoot

    Run this command and press Enter.

    bootrec /ScanOs

    Run this command and press Enter.

    bootrec /RebuildBcd

    Then reboot your System to see if Windows will boot up normally.

    2

    Go to Troubleshoot - Advanced Option - Startup Repair

    See if Windows startup can repair itself

    3

    Go to Troubleshoot - Advanced Option - System Restore

    Check to see if you have a restore point you can go back to

    The Stop error code 0x0000007B, also known as INACCESSIBLE_BOOT_DEVICE, typically occurs when the system cannot access the boot disk. This can happen due to various reasons, such as hardware changes, corrupted drivers, or issues with the Boot Configuration Database (BCD). Here are some steps you can take to troubleshoot and potentially fix this issue:

    1. Restart in Safe Mode: Boot your computer in Safe Mode. This can help revert any changes to driver settings that may be causing the issue. In Safe Mode, the system will load only essential drivers.
    2. Check Hardware Connections: Ensure that all hardware components, especially the hard drive, are properly connected. If you have recently changed any hardware, revert those changes to see if it resolves the issue.
    3. Run Disk Check and System File Checker: If you can access the Windows Recovery Environment (WinRE), run the following commands in the command prompt:
      • chkdsk /f /r OsDrive: (Replace OsDrive: with your actual OS drive letter)
      • sfc /scannow /offbootdir=OsDrive:\ /offwindir=OsDrive:\Windows
    4. Verify Boot Configuration: Use the bcdedit command to check the Boot Configuration Database for any incorrect entries. Ensure that the device and path entries point to the correct device and boot loader file.
    5. Use Startup Repair: If the above steps do not work, you can try using the Startup Repair tool available in the WinRE. This tool can automatically fix many common startup problems.

    If these steps do not resolve the issue, further investigation into the specific hardware and software configuration may be necessary.
