spock84 Posted February 3, 2008 Share Posted February 3, 2008 Installed using the kalyway 10.5.1 disc. Got Ubuntu on the main hard drive where the MBR is located (a SATA drive), using GRUB, and installed OSX on a secondary drive (IDE) as a guid partition. The motherboard is an Asus P5KC. This drive seems to have been set up with two partitions by the installer, a 200MB FAT partition and the main HFS+ partition. The FAT partition is flagged bootable. I assume this is the way it should be since the installer did this? Added the HFS+ partition to GRUB with fairly standard lines: name OSX root hd(1,1) makeactive chainloader +1 This is where I just get "HFS+ partition error" when I attempt to boot. Also tried "rootnoverify", but same thing happens. I've tried flagging the HFS+ partition as bootable (using gparted), which makes that error go away, but then the computer just hangs completely, no action at all. The partition looks just fine when I mount it in Ubuntu, no errors. This is probably a common problem, but I'm making this thread since I find the search function on this forum horrible.

spock84 Posted February 3, 2008 Author Share Posted February 3, 2008 Uh, no, that's a nonexistent partition. I've got the partition right.

spock84 Posted February 3, 2008 Author Share Posted February 3, 2008 I'm asking because I want help from someone who actually knows this stuff. Please don't answer if you're clueless. Anyone else? I tried using PC_EFI v8 to boot, but it has the same results.

spock84 Posted February 3, 2008 Author Share Posted February 3, 2008 Just reinstalled, this time with an MBR partition instead of GUID. Now it seems to be working. I thought it would be a problem to have two separate disks with MBR's, but I must've misunderstood the concept.
