I have a Macbook (from 2007) running Tiger OS X 10.4.11 Im trying to install Boot Camp onto the computer, but Tiger did not come with Boot Camp installed. Because of this i had to download Boot Camp 1.3 Beta. This is old, and has expired, but i changed the system date to be 2006, and this has made it work. When im partitioning the disk, this message comes up: Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again. I have already Backed Up and the computer is already formatted as Mac OS Extended (Journaled), but this message still comes up. Disk Utility has Greyed out the Erase section for Macintosh HD so i cant re-format it. Any suggestions?
