KrakenChaos Posted March 5, 2011 Share Posted March 5, 2011 I made triple boot on my Lenovo T410. I installed OSes in this order on a single harddisk - boot snow leopard with ModCD (tried [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], but can't boot after installed) - partitioned everything from snow leopard installer - installed snow leopard to 2nd partition (1st is EFI) - Able to boot Mac with Chameleon (installed along with mac from ModCD) - Installed Windows 7 - Chameleon is gone now - Windows itself can't boot either - Installed Ubuntu - Update everything - Installed gptsync - synced MBR with GPT - Now can boot Ubuntu and Windows from Grub GRUB display this menu - Ubuntu - Ubuntu safemode - Memtest - Mac OS X 32bit - Mac OS X 64bit - Windows 7 (loader) But I can't boot from Mac. A blank screen is displayed and restarted. Help? Any kind soul out there? Quote Link to comment Share on other sites More sharing options...
dake22 Posted March 5, 2011 Share Posted March 5, 2011 Hi! Since you say you've installed Ubuntu I assume you have GRUB2 as default bootmanager. I've found this tutorial, maybe it can help you to check everything is fine in the grub config: http://maketecheasier.com/create-a-mac-ent...rub2/2010/02/12 One hint: make a backup of any GRUB files you're about to edit!! This way if anything goes wrong you can restore them Salutes! Quote Link to comment Share on other sites More sharing options...

hotKoffy Posted March 6, 2011 Share Posted March 6, 2011 You should install OS in the following order : 1 windows first, as it will refuse to install or erase other boot loader... 2 OSX + chameleon or other like 3 Ubuntun, but pay attention at the end of the installation wizard to setup grub to install on /dev/sdax (x is the partition number where linux is installed) instead of /dev/sda (the MBR !).
