HackBook Pro Posted March 19, 2008 Share Posted March 19, 2008 Currently I have OSx86 10.4.11 installed. I also have Windows Vista and openSUSE installed. I use the Grub bootloader to multi-boot all 3. How can I setup Leo4All and still keep my Grub bootloader setup. And what is EFI, and should I install it? Thanks.

Wayfarer247 Posted March 19, 2008 Share Posted March 19, 2008 I use grub with my Leo install. I just added this entry to the .conf Grub file (or whatever file stores grub info in openSuse, you should be able to find that out): title Mac OS X Leopard root (hd1,0) savedefault makeactive chainloader +1 Where the "root" is where you Leo install is. What I would do is simply install Leo ontop of your Tiger installation. That way you won't have to change anything in grub to configure the new OS. Also, EFI is a must if you want to use the vanilla kernel, which I definitely suggest you do. I installed EFI + MBR, not GUID, and that didn't touch grub at all. If anything happens to grub, boot into openSuse (via LiveCD) and reinstall grub. This worked for me. Link to comment Share on other sites More sharing options...
HackBook Pro Posted March 19, 2008 Author Share Posted March 19, 2008 Thanks, OSX Tiger is set up that way in Grub. I was just worried that Leopard would mess up Grub. Link to comment Share on other sites More sharing options...
wmarsh Posted March 21, 2008 Share Posted March 21, 2008 Thanks, OSX Tiger is set up that way in Grub. I was just worried that Leopard would mess up Grub. For me the chainbooting method stopped working with Leopard. The PC_EFI method does work. http://forum.insanelymac.com/index.php?s=&...st&p=606752 Link to comment Share on other sites More sharing options...
Adamd Posted March 25, 2008 Share Posted March 25, 2008 Yeah triple booting is easy with OSX if you have a secondary drive dedicated but if its on the same drive as your Win and Lin install you might need to rewrite grub to the mbr. Kalyway will overwrite the mbr with the Boot MBR option checked on install. To boot using EFI you can simply place the boot_v8 file where grub is and add this to your grub menu.lst To edit menu.lst type in terminal: sudo gedit /boot/grub/menu.lst Add the following at the bottom: title OSX kernel (hdX,Y)/locationToEFI/boot_v8 X being the hard drive from 0 to n Y being the partition from 0 to n locationToEFI being the folder structure to the file If you do overwrite your Grub with the OSX installer do the following: Boot into your Linux Live CD of choice Get into the terminal Type the following sudo grub find /boot/grub/stage1 #will return a location root (hdX,Y) #use the location returned above setup (hd0) Exit terminal Restart Hope this helps others, ive had to do this a few times myself Link to comment Share on other sites More sharing options...
