Windows 7 installed But...

I went from windows vista 64 to windows 7 OEM, and have been having trouble for days. My latest trouble is that I finally got 7 to install, but when i restart or turn it back on it goes to gateway System recovery options! its been doing this all week. 7 is installed, but it wont boot to 7. I've tried as much as I can, searched the internet endlessly to no avail, if somehow someone can help, its very important as I need the computer to work! already lost all my files , though some important ones are on a hidden drive ( whole other story). If any more info is needed ask!
