Product: HP ProBook 450 G2
Operating System: Microsoft Windows 10 (64-bit)

I had the Black Death screen on my laptop. I am trying to use a bootable DVD to reinstall or repair my OS. I cannot access my operating system at all. I decided to reset my computer but get this message that says, “The drive where Windows is installed is locked. Unlock the drive and try again.” 

Where do I go from here? 

Thanks for any help in advance!

Hello @Tee_McBride 

 

You get this message because something is using your drive (something has locked it), for example BitLocker encryption. TPM information may also have been cleared. I recommend that you perform fresh clean installation by booting from new USB installation media - do not attempt repair/refresh.

 

Follow the instructions in the enclosed PDF file below - use Media Creation tool, create a bootable USB drive, boot from it and install (reinstall) Windows 10.

 

Hope this helps. Let me know how it goes
