We have a Lenovo desktop that's had 2 new hard drives installed because it appears, to Lenovo, that this is what's needed.
Now on the 3rd hard drive and unable to boot, we want to reinstall Windows 8.1 from an OS DVD.
(We now doubt that there's anything really wrong with the hard drive).
But, the computer won't boot from the DVD.
If we power down completely then F1 and F12 work.
Using F1 to get into the UEFI:
The Secure Boot option is disabled.
The boot order starts with the DVD.
With a cold reboot:
F12 doesn't give us the option to choose the DVD.
Selecting the Windows Boot Manager goes to the hard drive and a never-ending "repair" - which is where we're trying to move past.
If we don't use F12, then the computer goes to the hard drive as well and the same issue is presented.
We really just want to boot from the OS DVD so we can do a clean install of Windows!! How??
