bootcamp and when i try to load up vista it wont even go past the vista
loading page thing. even in safe mode. what it does is just get to the
loading page thing then the loading bar goes away (as usual) then the
BSOD flashes it doesn't stay it just flashes then turns off. so if
somebody can help me. btw i dont have the installation CD for vista so
i cant do the repair thingy but since i have it on my mac i can access
everything on the hard drive.
