I'm trying (in vain) to install Windows XP on my Mac Pro but I'm hitting a brick wall so far. Basically I used Boot Camp to partition my boot drive and I put in my Windows CD and rebooted, holding down 'c' to start the Windows installer. It loads up fine, but whenever it comes to selecting where you want to install to, I select the correct partition but then I am told that 'Windows needs to install some startup files' on one of my other drives, but it can't because it doesn't contain a valid Windows partition. Why is the installer wanting to write files to completely different disc? Basically I'm stuck. I don't want Windows writing anything anywhere but the partition I created for it using Boot Camp. For information, my Mac Pro has 5 internal hard drives and 2 Externals. (2 internals and 2 externals are used for an OS X Raid Array, the other two internals are just general storage and the last internal is my boot drive with the Boot Camp partition created on it). Could anyone please help me out? I'd be eternally grateful.
