I was trying to install windows on my new ASRock H81M-ITX motherboard and for some reason loading windows 7 pro 64bit to my OCZ agility 2 I got this error message:
Windows cannot be installed to this disk. This computer’s hardware may not support booting to this disk. Ensure that the disk’s controller is enabled in the computer’s BIOS menu.
BIOS saw 60GB SSD, the windows installer tool saw and let me format 60GB SSD, so if you are in my shoes and sounds similar, what I did to fix it was go to BIOS, enable SMART, DISABLE EXTERNAL (this seemed to do it), and enable HOT PLUG (not sure if needed, but I did enable).
Hope that helps!
