I have a PC running Windows XP SP2, and I face a problem in it and need my PC to boot in safe mode.
But when I choose safe mode from the boot menu, my PC restarts automatically!
So what's the problem?
You should get a linux livecd (SystemRescueCD or Parted Magic) and see if you can mount the hd. If you can, back up your data before you start trying to fix anything.
