Recently, I started up my computer only to receive an "NTLR is missing"-message. No problem, I figured, I´ll just go into recovery. After a couple of frustrating minutes, I found that I couldn´t, for some strange reason. After a bit more work, I now find that my computer doesn´t seem to recognize any of the drives. At least that´s what I assume, since the only visible option in the Boot Priority menu is "Bootable Add-in Cards", as well as any external drives I plug in. Can anyone offer some help?
