The day before yesterday, I received my new iMac. The first thing I did was partition the hard drive (one HFS+ volume for Mac OS X, one FAT32 volume for Windows XP and one HFS+ volume for all sorts of stuff) and reinstall Mac OS X. Today, I wanted to install Boot Camp to install Windows XP on the FAT32 partition I had created earlier. Alas, when trying to run Boot Camp, I get the following error message: "The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows." Fine, I thought, Boot Camp is only intended to partition your drive and to burn a cd with Windows drivers anyway. So I extracted the disc image with the drivers from the Boot Camp application package and burned it to a cd. Then I went ahead and restarted my iMac from a Windows XP SP2 install cd. And then the troubles arise. The Windows XP installer gives me a couple of options for where to install, but none of the options make any sense. There's an unpartitioned drive or something (can't remember the exact wording) and a drive with a size that doesn't correspond with any partition I made. Really weird stuff, if you ask me. In some old pre-Boot Camp-days manuals for installing Windows on an Intel Mac, I read that if you can only choose an unpartitioned drive or volume during the installation process, you should partition it (but should not REpartition it). Then, after a restart and back into the Windows XP installation process, you actually should see a partitioned drive and your Mac OS X installation should not be gone. But I don't want to risk losing it anyway. I mean, how do I know I won't overwrite the HFS+ volumes? Can anyone help me with installing Windows XP this way? Or should I just repartition my hard drive (this time with only one volume) and reinstall Mac OS X? That way, Boot Camp will surely work. The point is, I have just finished setting up the installation and installing all applications I use regularly. And, using an extremely slow and flaky internet connection, I have installed all Apple software updates. I really don't want to do all that again if I don't have to. Anyone? Help! And, oh yeah, I partitioned my drive using the GUID partition scheme. Should be correct, right?
