SilverZero Posted April 18, 2009 Share Posted April 18, 2009 I have GRUB installed on hd0, OSX on hd1, and I can boot into OSX from GRUB using the PC_EFI_v9 method detailed by wmarsh around here. Look him up, look for his guide. I actually modified it a bit, and I'm now tinkering with a new installation, so I'll check in next weekend when I've got my ducks in a row to see if I can help more. For now, look to wmarsh. He's got it dialed. The key, I think, is that GRUB needs to pass off the boot process to something that can emulate or initiate EFI, and then OSX has what it needs to boot. I may be wrong, but I know it works for me. Link to comment Share on other sites More sharing options...
