I have been trying to set up a windows partition using Boot Camp, But i keep getting an error saying it cannot be partitioned because some files cannot be moved. I have been fighting with it for a while to try to clear it up, but to no avail. So I was going to wipe my hard drive and reinstall Snow Leopard, this is where my question comes in. I bought the $29 SL upgrade disk when it came out, and did a clean install. But now that I want to wipe and reinstall will I be able to, with the upgrade disk, seeing that leopard is no longer installed. In short can I erase my HDD and install SL from the $29 disk?
