Edoir Posted September 12, 2012 Share Posted September 12, 2012 Hi there, I have change my old macbook 3,1 for a Sony vaio SVS13 I want to have a triple boot on this computer. So i have fully format my hdd then put it in external usb slot and connect to a Macbook air to set up Mountain Lion. Then i have put back the hdd to my Sony Laptop to set up Windows 7 pro X64. Then after all i have set up Ubuntu 12.04 X64. Ubuntu has detected Windows and Mac Os X so Grub 2 (in UEFI mode) has all the OS at the starting. So my hard drive is like that EFI | Macintosh HD | Microsoft Reserved | Windows 7 | Ubuntu. The problem is that i can't boot Mac Os... I have created a /Extra/Extensions with fakeSMC.kext inside i have also a DSDT file in /Extra I have try to edit the boot script in grub with xnu_kernel64 /mach_kernel boot-uuid=${uuid} rd=*uuid -x -v but nothing... Here is where i have found the info http://www.tonymacx86.com/mountain-lion-laptop-support/62142-mountain-lion-guide-2012-sony-vaio-s-series-svs.html#post415354 The fact is I want to boot with Grub and not chainload with an other bootloader.

rockinron_1 Posted September 12, 2012 Share Posted September 12, 2012 You have to chainload (or to keep things simple you should), use chameleon as your bootloader, set ubuntu timeout to 0. Edit: Extensions go in /System/Library/Extensions - /Extra/Extensions is depreciated after SL Link to comment Share on other sites More sharing options...
