rumpumpel1 Posted February 12, 2013 Share Posted February 12, 2013 I have a primary Ubuntu disk, which has a MBR, where the grub2 bootloader resides. On another disk I have a OS X 10.8 installation. The only way to boot into OS X is to choose the bootdisk with F12 from the BIOS menu. I would like to start OS X from the grub bootmenu. There are already two generated entries for 32bit and 64 bit, but neither of them works. Choosing one of these entries ends with a black screen. The OS X disk shows the following partitions: Partition Table: gpt Number Start End Size File system Name Flags 1 20.5kB 210MB 210MB fat32 EFI System Partition boot 2 210MB 400GB 400GB hfs+ Mountain Lion Can anyone tell me what exactly I have to put into /etc/grub.d/40_custom in order to get a working entry in my grubmenu for OS X ?

rumpumpel1 Posted February 13, 2013 Author Share Posted February 13, 2013 booting OS X shows me a boot-screen with three icons: OS X, Windows and Linux. Starting OS X works. Hitting on the Linux icon starts Windows and hitting on the Windows icon crashes.
