I'm currently running Snow Leopard at home and boot Windows 7 when I'm at work. I'd like to upgrade to OSX Lion so that I can take full advantage of iCloud. If I go thru the Lion install will that change what I've already got going on my other partition? I would think not, but I'm just not sure how Bootcamp deals with that. Also, due to some issues at work which are too long to explain here I'm also going to need to make some changes to my Windows partition at work. This involves getting rid of 7, installing XP, then re-installing 7 again. I saw in another post that you can't install XP with Bootcamp if you're running Lion. I assume then that I need to do these windows OS installs before switching to Lion? Any help is greatly appreciated! Thanks!
