Hi @Bachir00 

Welcome to the HP Support Community.

Thank you for posting your query.

The "Inaccessible Boot Device" error usually indicates a problem with your laptop's storage device or its connection to the system, preventing Windows from accessing the boot partition. Here are some steps you can take to troubleshoot and potentially fix this issue.

Check Physical Connections

Ensure that the internal hard drive or SSD is properly connected. This typically requires opening the laptop, so proceed with caution or seek professional help if you're not comfortable doing it yourself.

Boot into Safe Mode

Safe Mode loads a minimal set of drivers and might bypass the issue:

1. Turn off your laptop.
2. Turn it on and, as soon as the HP logo appears, press the F8 key repeatedly until you see the Advanced Boot Options menu.
3. Select Safe Mode with Networking.

If you can boot into Safe Mode, you can update drivers or perform a system restore.

Use the Windows Recovery Environment (WinRE)

Accessing WinRE can allow you to perform repairs:

1. Turn off your laptop.
2. Turn it on and, as soon as the HP logo appears, turn it off again. Repeat this process 2-3 times until you see the "Preparing Automatic Repair" screen.
3. Allow the laptop to diagnose the issue. If prompted, choose your account and enter your password.
4. In the recovery options, select Troubleshoot > Advanced Options.

From the Advanced Options menu, you can try the following:

• Startup Repair: This tool can fix certain system problems that might prevent Windows from starting.
• System Restore: Reverts the system to a previous state without affecting personal files, useful if the issue started after a recent change.
• Command Prompt: You can run commands to repair your system.

Run Check Disk Utility

In the Command Prompt, run:

chkdsk /f /r C:

This will check the disk for errors and attempt to fix them. Replace C: with the correct drive letter if your Windows installation is on a different drive.
