I tried using Apple’s Boot Camp to install Windows XP on my iMac with mixed results. I wasted a few hours and ended up removing the Windows partition.
The only Windows installation CD I have is a Dell-specific one, which also happens to be SP1 (Boot Camp requires SP2). I was able to get Windows XP up and running, but it was pretty useless. It wouldn’t recognize the iMac’s built-in ethernet, and the Mac driver disk won’t install in SP1. I also had a SP2 upgrade disk image, so I attempted to update it to SP2. Unfortunately the 8GB partition didn’t have enough space for the upgrade (even though it had a lot more than the installer required), so I wasn’t able to install the upgrade. I finally gave up and deleted the XP partition.
