Penguinshome Posted August 13, 2009 Share Posted August 13, 2009 Well, I just set up my new unibody macbook pro to triple boot into OSX, Windows 7, and Ubuntu 9.04. All of my operating systems work, but when I click either the windows or linux icon it goes to the grub bootloader. Any ideas on how I can have rEFIt link to the proper OS directly? Solution: In ubuntu type this into terminal: sudo dd if=/dev/zero of=/dev/sda2 bs=446 count=1 It should pt grub in the right place. When you restart there will be 2 linux icons in rEFIt. Both work and link to grub. Then all you need to do is pop in your windows disk and repair the boot files for windows. After you do that the extra linux icon will disappear.

SticMAC™ Posted August 13, 2009 Share Posted August 13, 2009 I think if you remove the Timeout in the com.apple.Boot.plist it wont show! there should be an option to do that in Ubuntu as well!?

johnlocke2342 Posted August 13, 2009 Share Posted August 13, 2009 Hi. I assume you just installed Ubuntu without customizing the install. The problem is that on a mac, you have to install GRUB on the partition on which Linux is installed. You should boot into Ubuntu and re-install GRUB on your Linux partition and type this into a terminal: sudo dd if=/dev/zero of=/dev/sda2 bs=446 count=1 it will delete GRUB from the mac MBR and you should be able to boot into the 3 OS as it should.

Penguinshome Posted August 15, 2009 Author Share Posted August 15, 2009 I figured it out. I did install grub on the wrong partition. What I did to fix it was to move grub to the right partition using some terminal wizardry. Then I popped in the Windows 7 disk and used it to repair the boot files. Everything fixed. Thanks all.
