Rammjet Posted October 5, 2006 Share Posted October 5, 2006 If you set up the hard drive with Disk Utility, you might have a problem. You are installing on a hard drive connected to a PC. BIOS performs the intial boot operations and it depends upon the hard drive to have the MBR partition scheme. Format the drive intended for OSX as FAT32. This will setup the MBR partition scheme with a tiny partition for the boot sectors and a big partition for whatever. When you install OSX, in Disk Utility, select the partition (not the hard drive) and format it to HFS+ (MacOS Extended Journaled). In Disk Utility the hard drive will appear at the top and the primary partition will appear right below it.

Beakster Posted October 5, 2006 Share Posted October 5, 2006 The petition is totally set to active and is Type AF. When I try to boot, I get this error: "HFS+ Partition Error" The SATA hard drive is disabled. Get a linux boot CD and run fdisk on usb drive. Make the mac partition active (bootable) and change the partition type to AF. That did it for me Link to comment https://www.insanelymac.com/forum/topic/29401-unable-to-boot-osx-from-external-usb-hard-drive-i-already-searched/#findComment-202674 Share on other sites More sharing options...
