HI @Othisdede,

Welcome to HP Support Community.

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

Enabling Secure Boot can sometimes trigger a repair mode loop, especially if there are compatibility or configuration issues. Here’s a step-by-step guide to address and resolve the issue:

1. Check Windows Compatibility:

1. Verify Secure Boot Compatibility:
   • Ensure that your version of Windows 10 is compatible with Secure Boot. Secure Boot is supported on Windows 8.1 and later. Since you're on Windows 10, this should generally be compatible, but make sure your version is up to date.

2. Update BIOS/UEFI Firmware:

• Go to the motherboard or laptop manufacturer's website and check for the latest BIOS/UEFI firmware updates for your model
• Download and install any available updates, following the manufacturer's instructions. An updated BIOS/UEFI firmware can resolve many compatibility issues.

3. Verify UEFI and GPT Configuration:

• Ensure that your system is set to boot in UEFI mode and not Legacy/CSM mode. You can check this in the BIOS/UEFI settings.
• Make sure your SSD is partitioned using GPT (GUID Partition Table). You can verify this in Windows using Disk Management:
  • Press Win + X and select Disk Management.
  • Right-click on your system disk (usually Disk 0) and select Properties.
  • Go to the Volumes tab and check if the Partition Style is GPT.

4. Check for Drive Integrity:

• Open Command Prompt as an administrator (Win + X > Command Prompt (Admin) or Windows PowerShell (Admin)).
• Run chkdsk /f to check for and fix file system errors on your drive.
• In the same Command Prompt window, run:
• After it completes, run:
• These commands will check and repair system files and the Windows image.

5. Reconfigure Secure Boot Settings:

• Restart your computer and enter the BIOS/UEFI settings (usually by pressing F2, F10, F12, or Delete during startup).
• Look for the Secure Boot option under the Boot or Security tab and enable it.
• Ensure that the boot mode is set to UEFI and not Legacy/CSM.
• Save your changes and exit BIOS/UEFI.

6. Check Boot Configuration:

1. Boot Configuration Data (BCD):
   • Sometimes, the Boot Configuration Data can cause issues. You might need to repair it using the Windows installation media:
     • Boot from a Windows 10 installation media (USB or DVD).
     • Select Repair your computer > Troubleshoot > Advanced options > Command Prompt.
     • In Command Prompt, run:

7. Perform a System Restore:

1. Access System Restore:
   • If the issue persists, you can try performing a System Restore:
     • Boot from Windows installation media and select Repair your computer.
     • Go to Troubleshoot > Advanced options > System Restore.
     • Follow the prompts to restore your system to a point before you made the changes.

8. Consider Reinstalling Windows:

• Before considering a reinstallation, make sure to back up any important data.
• If none of the above solutions work, you might need to perform a clean installation of Windows 10.

I hope this helps.

Take care and have a good day.
