A friend of mine gave me her old gateway computer that only has about 2 gig hard drive. I wante to format it and install xp. I did that but I messed up the install somehow and now I have 2 installations of xp. One is completely installed and the other just partial. Also my cd drive is not recognized even though I know it is working because I used it to install xp. How can I format the hard drive and start over. Help please!
