Do you have 2 CD/dvd drives? I had the same problem, like ross said, ithought i was booting from disk but wasn't. I was confused when reading people talking about "f8 to accept eula" when booting from cd because even though it said "press any key to boot from cd" and i did, it just kept loading windows. there never was a eula page that required f8 It took me two days to figure out that it was searching the wrong disk drive for my cd. I put the windowsxp cd into my second drive and it took me to setup, eula agreement, etc. and let me reformat. hope this helps anyone looking for info. I know im 3 years too late for the OP, but i couldnt find the solution anywhere online. so maybe this will help someone else looking for help.
