what both sites ,its a google search with a lot of sites ,should give you a idea what to look for in fixing you problem ,may not give exact fix ,but somewhere to start ,
the gist of what i read in most of the links i looked at is the computer is not seeing any boot device
Thank you joelbell, I am with the same problem, and at trying to set the boot option #1 to Windows Boot Manager it says Drive not present, but the drive should be there and not recognized. What can be wrong here? Shall I disable the boot option #2?
