The actual installation of Vista in using the Bootcamp partition manager is pretty easy. Just put in the Vista DVD and boot off of it and Vista will install. There is no need to delete the EFI partition (you only needed this in the early betas of Vista). About the bootcamp drivers, you MUST download the ATI/AMD graphics driver (for Macbook Pro/iMac) Mobile Catalyst 7.2 from ati.amd.com. I repeat, DO NOT use the bootcamp video drivers, as they are XP drivers and Windows Vista uses a different video driver model. A lot of drivers are automatically detected and installed by Vista, like the chipset drivers, etc. I'm not sure about an iMac, but on a Macbook Pro, the sound drivers must be installed manually by extracting the bootcamp drivers off of the CD and going into device manager to install it. Drivers for Appletime, brightness and iSight do not work (although they may install). Hope this helped.
