Not able to boot up in legacy or CSM mode to upgrade from Windows 8.1 to windows 10

[08jmooney]

When I tried to boot my laptop in Windows 10 it gave the error message "the selected boot device failed. Press enter to continue" after searching I found the solution was to switch to legacy boot mode however my laptop doesn't have that option, is there a version of the bios that will allow me to do this or any other way to fix the problem?

Thank you for joining HP Forums. 

I'll be glad to help you 🙂 

As I understand the device isn't booting into windows due to the error-"boot device failed",

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Did you perform a hard reset to release excessive static off your device?

Have attempted to reset the BIOS to defaults?

While you respond to that, Please follow the below steps to identify and resolve this concern: 

Step 1: Perform a hard reset 

HP Notebook PCs - Performing a Hard Reset or Forced Reset 

Step 2: Restore BIOS default settings 

Step 3: Test the hard drive using HP PC Hardware Diagnostics UEFI (In your case, Skip to Step 4) 

Step 4: Reseat the hard drive (here's a video that shows how to re-seat the drive: Click here) 

Step 5: Perform an HP System Recovery 

  

If none of the above actions resolved the error condition, back up your personal data and then perform an HP System Recovery on the notebook. See one of the following documents for instructions:
