Please help! I have a Toshiba Satellite C655-S5132 that just shut down & now will not boot Windows 7. Just goes to black screen w/blinking cursor then goes to 'startup repair' (which I'm postiive this is a virus of somekind) & will not allow me to do anything. Just repeats itself. I downloaded Windows 7 repair to a CD-R, chgd BIOS settings to CD/DVD to boot first, saved changes, and will NOT pull/boot up from disc. I've tried 2diff repair discs, both do not work. 'F8' does not do anything for me, not able to get to 'safe mode'. Computer is only 2yrs old.
