Need any help with that type of stuff, PM me; I crash my computer close to 3 times a week for the fun of it
I might point out that C_D was almost right.
To format:
1. Reboot your computer.
2. Boot into a DOS Command Prompt (BEFORE WINDOWS LOADS)
3. Type format <drive letter
4. It will ask you if you want to delete the data on removable disk <drive letter
5. Type y (yes).
6. It'll reformat it.
7. When it is done, reboot, edit your BIOS so the first boot device is CD-ROM.
8. Insert WINXP Disc, and reboot.
9. Boot from XP Disc, and follow instructions to reinstall Windows.
PM me if you have any other questions.
