looked around a lot online and never really found my specific problem.
I contracted one of the many fake antivirus trojans on my computer. I restarted so that i could boot in safe mode, use rkill and then run my antivirus to clean.
when restarting, my toshiba screen comes up, fans all whir including hd and cd, but the next screen is just blank witha blinking curser.
I can get to the startup menu by hitting F12, but not the safe mode menu or anything else.
i do not have a backup disc, i do have a free windows seven upgrade cd that came with the pc when i bought it, so i think i may be able to reinstall that via the boot menu and selecting cd, but i dont want to lose my hd if it isnt the problem in the first place.
