Access My Advanced Boot Menu To Start Windows Normally?

Everytime I restart the computer it boots into a repair mode,attempts to repair my computer, and then tells me "startup repair cannot repair this computer automatically". Why it's doing this I don't know,the system was working fine an hour ago.The only change I made was to attempt to make my RAID work, I rebooted, entered BIOS and changed my "Sata Operation Mode" to "RAID",then the problems started happening. I tried turning it back, even resetting BIOS defaults, but no go. During the boot up though I turned my comp off during the middle of windows loading, I wonder if that could have caused the problem?I know it's not recommended but it's something I've always done and never had a problem with.I've been trying to access my Advanced boot menu to start windows normally(perhaps it's stuck in some kind of repair cycle?) but pressing f8 does nothing, I've tried a thousand times.

I put in my Windows 7 disk and attempted a repair through there which halfway worked. When I boot up now it gives me two OS options to choose from, Windows and Windows 7 Home Premium (Recovered).The latter one boots up windows fine but all of my files are gone and it's telling me my copy of windows is not genuine! I had the majority of my data so it's not a huge deal to do a clean install but I would like to avoid that if possible.I'm using an asrock 890fx mobo with AMD processor.
