Here I found this webpage.http://www.sevenforums.com/tutorials/68 ... epair.html
"Startup Repair is located on the System Recovery Options menu, which is on the Windows 7 installation disc. If your computer manufacturer (OEM) has preinstalled recovery options, Startup Repair might also be installed on your hard disk."
Check your hard disk for Start-up repair is a starting point I guess...
Sorry I couldn't be more helpful at this point, but I have nothing better to do this evening so I guess I can look around a bit for you.
