Perhaps not safe mode as it seems you have a problem with your disk drive but the recovery console is accessible via the XP CD. Just press R or F10 when you get to the screen asking you if you would like to use the recovery console. It may not find a Windows installation if your hard drive has indeed gone bad.
A quick fix that sometimes solves hardware issues is to remove the power cable from the back of the machine for a while and then reinsert it and start up the computer.
