Hi @Siddubaba,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The "UNMOUNTABLE_BOOT_VOLUME" blue screen error indicates that your Windows system is having trouble accessing the boot volume, which is essential for starting up the operating system. This issue can be caused by several factors, including file system corruption, hardware problems, or configuration issues. Here are steps you can take to troubleshoot and potentially resolve the problem:

Troubleshooting Steps

1. Restart Your Computer

• Sometimes a simple restart can resolve the issue, but if it persists, follow the additional steps below.

2. Boot into Safe Mode

• Access Safe Mode:
  • Turn on your computer and repeatedly press F8 (or Shift + F8) before Windows starts loading to access the Advanced Boot Options.
  • Select "Safe Mode" or "Safe Mode with Networking."
• If you can boot into Safe Mode, you might be able to perform additional troubleshooting steps.

3. Use Windows Recovery Environment (WinRE)

• Access WinRE:
  • Restart your computer and interrupt the startup process three times (e.g., by turning it off during the boot process) to trigger Windows Recovery.Alternatively, use a Windows installation media to boot into WinRE.
• Run Automatic Repair:
  • In WinRE, select "Troubleshoot" > "Advanced options" > "Startup Repair" to let Windows attempt to fix the problem automatically.

4. Check Disk for Errors

• Using Command Prompt:
  • In WinRE, go to "Troubleshoot" > "Advanced options" > "Command Prompt." chkdsk C: /f /r Run the following command to check and fix disk errors:sfc /scannow
  • Replace C: with the drive letter of your boot volume if it’s different.

5. Check and Repair File System

• Using Command Prompt:
  • In Command Prompt from WinRE, run: This command will check for and attempt to repair corrupted system files.

6. Update or Roll Back Drivers

• If you can boot into Safe Mode or WinRE, try updating or rolling back recently installed drivers. Corrupted or incompatible drivers can sometimes cause boot issues.

7. Reset BIOS/UEFI Settings:

• Restart your computer and press the appropriate key (e.g., F2, Delete, Esc) to enter BIOS/UEFI settings.:
  • Find the option to restore BIOS/UEFI settings to default. This can help if incorrect settings are causing the issue.

8. Perform a System Restore:

• Go to "Troubleshoot" > "Advanced options" > "System Restore."
• If you have restore points created before the issue started, you can restore your system to a previous state.

I hope this helps.

Take care and have a good day.
