Boot Camp is a Leopard tool that lets you run Windows on your Mac.
It partitions your hard drive so you can dual boot to more than one OS, in this case Leopard and Windows.
This page is not a tutorial on Boot Camp, but rather just a few things I have learned that may prevent others from having issues.
When you get to the step where you do the Windows install, make sure that Windows lets you select the installation drive.
And be sure you select the right drive (partition).
I have seen many posts about people who have loaded Windows over Leopard.
I have installed Windows with Boot Camp twice.
One of the times, when the Windows install was ready to start, I did not have the selection option.
Had I continued with the install, I would have installed Windows over Leopard.
In that instance I shut the machine off and restarted.
I am not sure why this happens, but I have read enough about it to know it happens quite frequently.
If you install Windows XP using the Fat32 file system, you can copy files back and forth between partitions when in Leopard.
This can, of course, be very handy.
However, do not delete files from the Windows partition from within Leopard.
I have learned that the trash processing in Leopard can create invalid file names (using invalid characters) in your Windows partition.
This puts garbage in the Windows partition and creates future problems for Leopard trash handling (since it looks at the Windows partition).
It is best to only delete files in the Windows partition from within Windows.
Be sure you run Apple Update from within Windows before doing major Windows upgrades.
This will help ensure your Windows partition continues to work properly with Boot Camp.
