When you use the CD to boot you will see the Windows ssetup..the option to format will be in there. Just have to wait for setup to laod. It will ask if you want to repair dont. Make it do a fresh install. It will then show Keep as is, format with FAT(quick), Format with NTFS(Quick), Format with FAT, Format with NTFS (recommend). It isnt hard to miss just have to wait till after the setup loads files needed. Then about 30-60 minutes for it to install.
