I spent a torturous day yesterday installing Bootcamp on my new dual core mini. Some lessons that I learned along the way:

• Reformat your partition. Although the bootcamp utility creates a FAT partition for Windows before you begin the XP install process, you must reformat that partition during Windows setup or you will get Bad Disk errors. I personally went with FAT for the reformat.
• Pick the right partition. It’s so easy to gloss over Apple’s instructions that you might miss the part about having to search for C: on the partition list. Fortunately, I caught myself right before I almost reformatted my OS X partition.
• Check your sounds. On my Intel core duo, the Realtek drivers would not install. I ended up spending hours trying to figure out why the “Microsoft Bus Driver” wasn’t working. In the end, I had to update my PCI devices as follows: Right-click My Computer. Choose Properties -> Hardware -> Device Manager -> System Devices. There was an incorrectly installed PCI Device (with a yellow caution symbol next to it). Double-clicking that let me re-install that driver. (At this point, Windows complained that I had overwritten original Win XP SP2 files, but I cancelled its complaint and kept the ones that had been installed on the Mac drivers CD.) The Realtek driver can be found on your C: (local disk) drive, in Program Files : Macintosh Drivers for Windows XP 1.1.2 : realtek. Double-click Setup.exe to install.
