JonZ Posted May 9, 2008 Share Posted May 9, 2008 I tried the dual boot method from I am...me, it worked. Things got bad when I installed uBuntu 8.04. After the installation, my OSX was no more bootable, I had a black screen with a blinking cursor. I tried to go with uBuntu live CD, I tried to put boot_v8 in the /boot partition, edited the menu.lst and rebuild the mbr. Grub started, but OSX was not found (error 15) and my Vista partition was no more bootable because of partition error. Seems more complicated than I thought. I feel I still can make it work with the Darwin Loader, Just now I was able to recover OSX Darwin with the possibility to load Grub and Vista. But I rather having to boot with Grub. Help?

Here is my guide. http://forum.insanelymac.com/index.php?s=&...st&p=606752 Error 15 is file not found. Make sure that boot_v8 is in the same location as your Linux kernel (usually /boot) and that the path in menu.lst to boot_v8 is the same as the as that to the Linux kernel in the Linux entry.

Make sure that boot_v8 is in the same location as your Linux kernel (usually /boot) and that the path in menu.lst to boot_v8 is the same as the as that to the Linux kernel in the Linux entry. Well, funny thing is I was following that guide before realizing nothing worked at all and make a thread about it. I'm pretty sure to have followed your guide correctly but it doesn't work properly. When I write find /boot/grub/stage1, it says not found. So I assumed the setup would actually take place in the same HD location. as for the boot_v8 file, i'm pretty sure I copied it to the right emplacement, one thing your method doesn't mention is if you have a partitionned boot, which I currently have. With the Live CD, the boot and grub doesn't coexist in the same path. EDIT: OK, After countless hour of try and trials and doc readings, I have found out it almost impossible. The way I am doing it that is. I've learned that once you make a GUID partition and convert the other partition into FAT for installing foreign OS, it become GPT+MBR hybrid partition. Vista doesn't support EFI and GUID partition AFAIK. And GTP+MBR doesn't support more than 4 partition. Sooo, the way I was partitioning was not good because it was not supported by Vista (uBuntu I don't know at this point, but I believe it was since it was still bootable) because I was trying to make more than 4 partition. What happened is once I installed uBuntu with the 3 partition (/. /boot, swap) plus the storage partition, the partition was 'canceling' the MBR and convert the HD into GTP or a dynamic hard drive. Everytime I was doing it, I would loose the Vista (the partition still there but no more accessible). So at this point it is impossible to me to triple boot using GUID/EFI, unless maybe to confine Linux to only one partition by including the swap and the boot and make sure to not make storage partition, which is not really a good practical solution, unless I add another HD which I can't since it a laptop.

wmarsh Posted May 11, 2008 Share Posted May 11, 2008 I don't use guid. But you can do what you want with mbr partition table. Linux boots quite nicely from and extended partition. And your swap and data can also be in extended partitions. In fact that is how I partition: 1 HDD: 1st primary partition: Vista 2nd Primary partition: FreeBSD (with different slices for boot, user, etc.) 2 HDD: 1st primary partition: XP 2nd primary partition: Leopard 3rd primary partition: container for extended partitions for Linux (boot,data,swap) 3 HDD: 1st primary partition: Leopard backup 2nd primary partition: data 3rd primary partition: copy of OS X install DVD (I had to add dev ids to support ICH8r raid mode) will be deleted when I need space.

p_noch Posted June 7, 2008 Share Posted June 7, 2008 i have a completely perfect tri-boot (GUID-EFI) [Leopard 10.5.3, Vista x64, Ubuntu x64] by using ubuntu grub.
