Well, I realize this is an old thread, but I am having the same issue.
I AM using RAID, and an official Windows 7 Ultimate x64 DVD. I made a backup of my system when one drive in my array went bad (RAID5), then decided to go to 2 SSD's in RAID0.
First I found that the backup I made is incompatible because the backup was made using an EFI BIOS. When I first installed Windows 7 I don't recall there being an option, so I assume the motherboard was set for it or something.
Finally, after all weekend trying things and looking stuff up on the internet, I have reverted to a USB DVD, which when I look at the boot menu it is in there twice, once as a 'normal' slim drive and once as a 'UEFI' slim drive.
I of course chose the UEFI because that is what my backup is on and got the system recover options is not compatible ....
Now I NEED to have my Harddrives plugged in because my backup is on one. Disconnecting drives is a stupid option, in my opinion. Is there a patch or fix that will fix these show-stopper problems? I mean an average person with a computer will NEVER figure
this stuff out.
