Hey Everyone,
I was wondering if anyone was having the same issue as I am installing this service pack for Vista 64-bit. I keep getting "100%.... reverting changes", come to find out the error code (0x80004005) came up to be that if you have any bootloader (grub, chameleon, etc...) other than the windows on initial install of Vista, the service pack updates will fail.

I was wondering if anyone ran into this issue and has a way to bypass it.

Haven't experience the problem, but my advice: Booot into the BIOS, disable the drive that has chameleon/osx on it. (Assuming you have 2 drives) Then, boot up with only the windows disc and it should work.

The service pack won't install if you have your OSX drive in the pc, just unplug it, install the service pack then plug your osx drive back in. If you have Vista and OSX on the same drive then I don't know.

Unfortunately i have 3 partition on one drive each with vista ubuntu and osx. I am still trying to figure it out.
