Is known, everywhere I go i read that if i want XP64 and XP32 in dual boot I have to install 32bit first and 64bit after. Is true, this works, I did try in the past. My problem is that I installed XP64 and now i woke up that i need XP32bit for Avid Xpress Pro that won't install on 64bit. How can I install safely XP32 now to have dual boot without loosing anything from my already installed 64bit? Anybody can give me a guide on this?
