Hi, let me get to the point:
Friend brought over an HP All in one 20-b323w. Boot up message says:
So I went inside its Recovery, and ran Automatic Repair multiple times to no avail, so I went to disable Secure Boot, and tried this:
The Boot configuration data for you PC is missing or contains errors.
Error code: 0x000000f
But the result is this:
Also, I think C: is not marked as active, but it says I can not mark it as active.
I don't know much about UEFI at all, and it was so much easy with the old BIOS MRB fixes with just a few commands.
What can I do, and what kind of more info would you need?
