For your viewing pleasure I have attached some pics of my BIOS, which I flashed to the latest (1703) - see attached evidence.
Also, pics of other relevant settings.
Now before you jump to the rather tempting conclusion that I am
Brilliant Beyond Description, please allow me to be perfectly honest.
I have no idea what the hell I did right!
At any rate I did Startup Repair several times (within Startup Repair - yes, I know that makes zero sense), tried taking the OS Setup DVD out of the drive and again encountered the same error message: Please insert proper yada yada ...
OK, then instead of using Binary Decision Tree Logic, I used Magic and Witchcraft (I can explain how to do so later.
)
I rebooted, this time leaving the setup disk in the drive. I sat there and just waited. And Bingo! A menu came up that asked me what OS I wanted to boot to. How about that! OK, so I chose the only one offered (Win 7) and it booted nicely.
Now, because I have become somewhat fearful, I have not tried to do a restart to see if Win 7 would come up as it should.
Any suggestions as to how to proceed?
