when i boot my pc and i try to access safe mode (f8) all it does it ask me which device do i want to use to boot my pc. like my dvd-rw and/or hard drive. no more safe mode? why? it's been like this for awhile and can't figure it out. i HAVE NOT formated and i HAVE updated bios (if that even helps in this matter). what else could i do or even try?
