Ok. Ive struggled for 3 days

and now I need the help of my fellow locks...
Long Story short... My windows folders were corrupted to the point that not even safemode would boot it and the XP install/repair is completely unaccessible.
*Sigh* I need to format my harddrive, but I cannot figure out how to do so without starting windows... and I CANT seem to get anything to cooperate.
What I need is some sort of bootable CD to format my drive. All attempts at 'tech web sites' were met with a "WHAT A JERK! SOUNDS MALICIOUS" etc... All I want is my baby to get better!
Any advice/tips/suggestions are GREATLY appreciated!
Oh. Windows XP, not vista.
(All I want to do is grind out that last level for my flyer

)
