    Triple Boot Startup Problems

    I just configured my machine to run Max OS 10.5 (Leopard), Windows 7 64-bit, and Ubuntu 9.10 64-bit. It took some trial and error, but the process I ended up using was to take a clean install of OS X, use bootcamp to partition and install Windows, then reboot back to OS X and use Disk Utility to split the Mac partition to make room for Ubuntu. All three operating systems are running pretty well, but it's kind of a hassle to boot to the different operating systems.

    If I restart the computer GRUB starts and gives me the following options:

    Code:
    Ubuntu, Linux 2.6.31-14-generic
    Ubuntu, Linux 2.6.31-14-generic (recovery mode)
    Memory Test (memtest86+)
    Memory Test (memtest86+, serial console 115200)
    Mac OS X (on /dev/sda2)
    Windows 7 (loader) (on /dev/sda4)
    This works well for both Ubuntu and Windows, but if I select Mac OS X, I get a lot of console output that eventually ends in:

    Code:
    AppleIntelCPUPowerManagement: initialization complete
    Still waiting for root device
    If I let it sit longer, it continues to loop on the "Still waiting for root device" message and never boots. In order to boot to OS X I have to hold the option key during startup where I'm presented with a choice between "Macintosh HD" and "Windows".

    I tried rEFIt and didn't see any change to startup.

    I would like to get a single boot screen where I can select between Windows, Ubuntu, and OS X. Something like this:



    If I could do this in GRUB, that would also be OK. I would greatly appreciate any help on the matter.

    It would be interesting to see what "code" is executed when the mac option is choosen in grub.

    Either find the mac os x entry in /boot/grub/grub.cfg (in your linux system) yourself, or run:

    sudo cat /boot/grub/grub.cfg | grep "Mac OS X" -A 10

    in linux and paste the output here.

    Re: Triple Boot Startup Problems

    Sure. Here's the entry:

    Code:
    menuentry "Mac OS X (on /dev/sda2)" {
    	insmod hfsplus
    	set root=(hd0,2)
    	search --no-floppy --fs-uuid --set 51dbbfe84a7d03e3
            insmod vbe
            do_resume=0
            if [ /var/vm/sleepimage -nt10 / ]; then
               if xnu_resume /var/vm/sleepimage; then
                 do_resume=1
               fi
            fi
            if [ $do_resume == 0 ]; then
               xnu_uuid 51dbbfe84a7d03e3 uuid
               if [ -f /Extra/DSDT.aml ]; then
                  acpi -e /Extra/DSDT.aml
               fi
               xnu_kernel /mach_kernel boot-uuid=${uuid} rd=*uuid
               if [ /System/Library/Extensions.mkext -nt /System/Library/Extensions ]; then
                  xnu_mkext /System/Library/Extensions.mkext
               else
                  xnu_kextdir /System/Library/Extensions
               fi
               if [ -f /Extra/Extensions.mkext ]; then
                  xnu_mkext /Extra/Extensions.mkext
               fi
               if [ -d /Extra/Extensions ]; then
                  xnu_kextdir /Extra/Extensions
               fi
               if [ -f /Extra/devtree.txt ]; then
                  xnu_devtree /Extra/devtree.txt
               fi
               if [ -f /Extra/splash.jpg ]; then
                  insmod jpeg
                  xnu_splash /Extra/splash.jpg
               fi
               if [ -f /Extra/splash.png ]; then
                  insmod png
                  xnu_splash /Extra/splash.png
               fi
               if [ -f /Extra/splash.tga ]; then
                  insmod tga
                  xnu_splash /Extra/splash.tga
               fi
            fi
    }
    Let me know if there's anything else you need to know.

    Re: Triple Boot Startup Problems

    Thats a lot of code! I believe this OS X entry did it for me (I don't have the same setup anymore, so I can't check):

    Code:
    menuentry "MacOSX (verbose mode)" {
      # Set the root device for Mac OS X's loader.
      root=(hd0,2)
      # Load the loader.
      chainloader /usr/standalone/i386/boot.efi -v
    }
    Otherwise there are a couple of more alternatives on this site:
    http://grub.enbug.org/TestingOnMacbook

    (they're all a lot shorter, if nothing else )

    Re: Triple Boot Startup Problems

    Unfortunately both the one that you provided and the ones at the link you sent me give an error ("Invalid signature" for the one you provided and "Unspecified search type" for the one on the other page).

    I noticed that both methods refer to "/usr/standalone/i386/boot.efi". When I checked my file system, there isn't even a /usr/standalone/ dir, let alone a boot.efi file. Am I missing something?

    Re: Triple Boot Startup Problems

    Double-checking here - has anyone been able to boot Mac OS X in GRUB 2 (1.97 beta) yet? This is kind of my Holy Grail at the moment. Then I can worry about cleaning up GRUB to look the way I want.

    Hmm, interesting. It worked without problems for me (but I don't have that dir either, strange).

    I was using the EFI-boot described at the link I gave you, I guess you were using the MBR variant?

    Only by EFI-booting grub2. But I couldn't boot linux properly that way (graphics problem) so it's not anything I'm using

    Re: Triple Boot Startup Problems

    Aah, it just struck me:

    It first sets root=(hd0,2), so its in your os x file system you should look for /usr/standalone.

    Also you probably need to add insmod hfsplus (and possibly insmod vbe, telling from your old entry). So maybe try something like this:


    Code:
    menuentry "MacOSX (verbose mode)" {
      # insert modules:
      insmod hfsplus
      insmod vbe
      # and possibly something more...
      # Set the root device for Mac OS X's loader.
      root=(hd0,2)
      # Load the loader.
      chainloader /usr/standalone/i386/boot.efi -v
    }
    I chose the hfsplus module when I compiled grub, thats why I didn't need it.


    You've noticed that you can press 'c' and 'e' in the grub menu, quite convenient when experimenting with different options.
