Just got my first Mac last night, MBA 2.13/128SSD. So far it's been a questionable purchase, the two things I need it to do I cannot do with Mac OS X and Safari. Need to use a digital ID for law school which won't install in safari and can't watch Real Player lectures as I cannot enter log in info. Installed Vista Ultimate using Parallels (have not tried VM Fusion) and it works but the videos lag. I partition 10G in Boot Camp and tried to install (1st) Vista Ultimate, (2nd) XP, (3rd) XP SP2, (4th) Windows 7b, none of them worked. After I set the partition and select to install, the Mac reboots and then the gray Apple screen appears with an Apple Logo and Folder. I've searched for hours on Google and I can't find a single article that answers my question as to why this is happening and how to avoid. I realize I cannot use XP, but Vista Ultimate and XP SP2 and possibly W7 should have done something.. Thanks for your help I really don't want to return this thing but I'm regretting it thus far.
