Rebel581 Posted June 15, 2009 Share Posted June 15, 2009 I'm (trying) to run a triple-boot system with Windows XP, Ubuntu 9.04, and OSX86. I've installed them in that order. But now, when I start the computer, it always goes into the Darwin bootloader. The Darwin bootloader shows the XP and OSX installations, but the Linux installation isn't present. When I use fdisk to look at my partitions, it shows Windows XP at disk0s1, OSX at disk0s2, and Linux at disk0s3. I set disk0s3 as the active partition and it still loads Darwin. When I set disk0s1 as the active partition, it loads straight to Windows XP. Why does this keep happening? I would rather use the grub bootloader to control all of my installations, but now I can't even get into the Linux partition of my HDD! How do I fix this?

Well I haven't ever done a Windows/Linux/OSX86 multi-boot (since I'm having trouble even getting into the OSX installer on my computer) But I have done Windows/Linux dual boot before, where this has happened to me. It was when I installed linux first, then windows after. Windows overwrote the MBR to boot straight to windows... What you have to do is get your Ubuntu Live CD! boot up from that, then restore grub to the MBR! Here is a guide, http://ubuntuforums.org/showthread.php?t=224351 If your mac or windows install is not showing up on the boot loader list, you'll have to boot up from the ubuntu live cd again, and change the menu.lst file in /boot/grub So i think you should double check that file, after restoring grub just to save some time in case it does need modifying... Best of luck. By the way how did you install Mac OS X on a partition instead of the whole drive? What order did you install the OS's in? Wait a minute what do you mean by "setting as the active partition"? Are you sure disk0s3 is linux? maybe they are mixed up, try setting disk0s2 as the active partition maybe Link to comment https://www.insanelymac.com/forum/topic/170914-darwin-bootloader-overwrote-grub-bootloader/#findComment-1178656 Share on other sites More sharing options...

Best of luck. By the way how did you install Mac OS X on a partition instead of the whole drive? What order did you install the OS's in? I installed it Windows XP, then Linux, then Mac OS X. I originally installed Windows XP on the entire hard drive. I used Acronis Disk Director to resize my partitions. I installed Linux on that partition. Then I resized it again and installed Mac OS X. I did that by going into Windows XP after I resized the HDD, Control Panel > Administrative Tools > Computer Management. Then I told it to format the unused partition space. I can't remember what the exact options are, but you tell it to format. But then when it bring up the options, you tell it not to format the disk and not to assign a drive letter to it. Just format it as a primary partition without doing anything else. I'm downloading the Ubuntu Live CD right now (I have 8.10, not 9.04). So hopefully this will work.
