Here's a very simple solution...wipe your drive completely. this will get rid of anything hindering the installation and operating of the OS. When you first install XP it should tell you what and how many partitions you have, also this same screen allows you to make new partitions. Delete the old ones format your HD and make new ones. this should solve your problems. PS: if you have an MS DOS disk use it. after your PC starts off this disk type, slate 1 on the command prompt, this will erase the drive completelty and leave it ready for a fresh install, plus it gets rid of half of the steps above.

Ask me a question, and I'll give you an answer.
