Hi, I have a Sony Vaio GRX520 laptop that has a 30 GB hard drive installed in it. The drive appears to be divided into two partitions as there is a both a C: and D: for the hard drive. Windows XP Home edition came preinstalled on the machine. However, I would like to use Windows XP Pro for some things that I can't do with WinXP Home. But, I want to keep XP Home on the machine. My question is, can I simply install XP Pro on the second partition and just do like a dual-boot setup? If so, is it as simple as installing XP Pro on the second partition and that's it? If I can't do it, why not? Thanks a lot!
