Welcome to Geeks to Go
My keyboard won't work for selecting any options at that menu or boot-up
I appreciate you say - or at boot - after first post screen will it allow you to enter BIOS setup
If so see if you have there enable legacy usb
If you cannot get in to that or to F8 advanced startup and then repair your computer, you will have to obtain, if you do not have it, the windows 7? disc and try a boot from that
It would be helpful if you could post the full details of the computer make and full model if branded eg Dell Inspiron etc
and confirm please the Operating system in full eg Windows 7 Home Premium, Professional etc.
The other approach maybe a chkdsk but I can advise you further when I have some details
