Step 2. Burn the Mac drivers disc. Boot Camp will prompt you to insert your blank CD/DVD to burn the Mac drivers disk. These drivers will make your Mac's video card, Bluetooth, iSight, wireless and IR remote work in Windows, so this is also a crucial step.
Sep 3. Partition your Mac's hard drive. Using the Boot Camp Assistant, you'll set exactly how big you want your Windows partition to be. I chose 20GB, but it depends on how much space you need to work in windows. Keep in mind that a partition larger than 32GB cannot be formatted as a FAT volume (but can be NTFS.) FAT volumes can be written to within OS X (while NTFS volumes cannot), but FAT is considered less reliable than NTFS.Note: Please close all the applications and windows before click the partition button.
Step 4. Now after you have partitioned, insert Windows Xp CD and wait for Mac to recognize it and then Click Start Installation and it will start the Installation of Windows Xp.
Step 5. Insatall Windows Once your partition's created, insert the Windows installation disk and hit the "Start Installation" button in the Boot Camp Assistant. Your Mac will reboot on the Windows XP disk and begin the OS installation.
Two things to know when you're installing Windows XP:
When it comes time to select the partition to format, choose the C: partition. One false move here and you could wipe out your entire Mac.
You'll have a choice between the NTFS or FAT Windows partition format. NTFS is recommended, though FAT is ok too.
Complete the rest of the Windows XP installation as usual.
Step 6. Install the Mac drivers. Once you're completely booted into Windows, eject the installation disk and insert the Mac drivers CD you burned earlier and let Autorun take over. Once these drivers are installed, Windows will recognize your Mac's devices (like Bluetooth, the video adapter, iSight camera, and wireless receiver.) You'll have to reboot to finish this installation.
You're done! You now have the choice to start either Mac OSX or Windows XP on your Mac. To make that choice, hold down the Option key when you restart your Mac, and choose your boot partition.
