When I start my computer and want to start XP in safe mode by pressing F8 it seems to work but before the safe mode is reached the computer restarts and comes up with the "dos" screen telling me what I want to do (last known configuration, normal start safe mode etc). When I select "normal start" xp boots normal. Also I tried the "/safeboot" in msconfig and this also doesn't work. This is even worse because now I'am not able to start up XP anymore. PS: virus definitions are up to date. Also performed full system scan but no virus. No adware found with AD-aware SE with definitions up to date. Can anybody help me? Xp is running well, but in future I may need safeboot.
