I have a Lenovo w/ Vista Busines installed but it's so loaded with trialware so I plan to wipe it out and use my own CD. I also want to put on XP. The HD is 200GB so should be big enough. My question is which OS should I install first. Also, if you have a 3000N Lenovo series, which software is really needed after you install all drivers? I heard about a software called VistaBoot. Do I really need it? Thanks for all inputs.
