I think if you've already installed SL, your HDD is probably set up as a GUID and I don't know of a way to get XP to install on a GUID drive. So I'm thinking you may have to start with a fresh install of XP, then do SL second. I'd keep looking around to see if anyone has had success going the other way.
If you send me your email address, I'll send you a copy of the OSInstall.zip.
Hey you replied to my post about dual booting XP/SL. I asked about it being a fresh install since I already have SL on my 10v and your guide was meant for a preexisting install of XP. I suppose I can reinstall XP and then follow your guide...just thought there might be an easier way.
After looking at your guide, do you have a working link for the OSInstall file? I looked for it online and found some links, but I want to be sure it's the same version.
