I was originally running just XP Pro (and still use as my main OS) on C:. Installed Vista (didn't activate it yet and it's past 30 days) on Drive G:. Installed Ubuntu on D:. Installed Windows 7 RC1 son S: (in that order). When I start my puter, Windows 7 is the Default OS. I can't change the default OS to XP in Windows 7 (it only gives me the option for Vista). When I start in XP it shows Windows 7 (7 and xp only options) as default and when I try to select XP as default it jumps right back to 7. I'm thinking I may have to activate my Vista and do it thru Vista... [all OS run perfectly no issues at all] Thoughts? Ideas? Trying to save time... Thanx!
Easy method is to download and install this program, EasyBCD and you can change the default OS and even choose XP. And it's also pretty neat because it allows you to change the names of the OS's on the Boot Manager.
