OK, the title pretty much says it. I just popped a 256GB Samsung SSD into my (old) PowerBook Pro1,1 2.16Mhz machine. I used the disk utility to properly partition the drive (1 partition) and set the Scheme to GUID Partition Table successfully. Verified the drive and the disk utility seems to like it. I restarted with the install DVD (10.5.7 from a "13-inch Mac OSX Install Disk" - 9J3050) and it still gives me the old, "You cannot install Mac OS X on this volume" So... the OS is newer than the one that shipped with the machine, and the partition table is correct... what gives?
