Hey guys, need some help. My gf got the ups virus and now I can't get to the boot screen or bios screen. It's basically stuck on a black screen with just an underscore. Tried pressing f8 but no luck. I tried using usb recovery for windows 7 but it wont read the usb stick? I tried by turning it on and holding option, which popped up mac drive and windows drive, but no usb? I can locate the virus from logging into osx, but from osx the windows drive is read only? Can I change it to read/write so I can get rid of the virus? Any other ideas?
