[Jenni32]

Can't get into my computer. Shows Invalid signature detected. Check secure boot policy in setup.

I can hit enter and then it says Boot Device not found.

Hi @Jenni32,

Welcome to the HP Support Community.
 

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

Thank you for contacting HP Support. The message: “Invalid signature detected. Check Secure Boot Policy in Setup “followed by: “Boot Device Not Found”  usually points to either:

• Corrupted boot files, 
• Secure Boot/BIOS boot configuration issues, 
• Or possible SSD/HDD detection failure.
   

To guide you with the correct recovery steps, could you please let us know the exact HP model name or product number of the PC/laptop?
 

In the meantime, please try this quick check:

1. Turn the PC OFF completely. 
2. Turn it ON and repeatedly tap: 
   • F2 → Run HP Hardware Diagnostics 
3. Check: 
   • Storage/SSD Test 

If the drive fails or is not detected, that would explain the “Boot Device Not Found” error.
 

If the drive passes:

• Restart again and tap: 
  • F10 → BIOS Setup 
• Check whether: 
  • The SSD/HDD is listed under Storage, 
  • And whether Secure Boot/UEFI settings were recently changed.
     

Once you share the exact HP model, we can provide the proper recovery steps specific to your device.

I hope this helps.

Take care and have an amazing day!
