Running win 7 on a 3 year old Dell Inspiron. Left the machine on overnight Tuesday. Wednesday morning it was showing the enter password login screen. I assumed it downloaded updates overnight & rebooted. Would not accept password & when I clicked forgot password it said to install the floppy or USB device that contained the password record. That's when I noticed it was showing drive d instead of c. Restarted, F12, changed boot order to hd, save, exit. Aaaand it's still showing drive d. Repeated steps many times with no difference. When I hit F2, it shows the hd in first place. When I hit F12, it shows floppy/USB in first. Win7 repair disc finds no problems. Tell me I don't gotta reinstall.
