Triple Booting
Wednesday, December 13, 2006
Triple booting can be a tricky issue. But, with the right preparation, it can be done. This post is inspired by a reader who left a comment on the message board, I will try my best to answer it.
for every operating system you want to boot. First line denotes the title you want the entry to have. The second line specifies where the OS is present. The third and fourth address where the boot image is found, and the fifth and sixth finish it up.
Do get a better idea of what to enter, Google is your friend. Search editing GRUB boot entries, or GRUB. Ask around at forums, to see what exactly to put for you specific distro.
Another option is to reinstall GRUB.This is not as difficult as it may seem. A good guide to follow is on the GRUB page. This process uses the "Alternate Install" on the Ubuntu CD. You can also use the Super Grub Disk. Read up on how to use it @ the Super Grub Disk Documentation Page.
Another great article to reference is on the GRUB page. This fairly detailed and easy to follow HOW-TO, shows you how to add multiple Linux OS's to GRUB, and have them boot/ appear properly. Although not exactly pertaining to this question, it is helpful in learning how to edit GRUB.
Also, learn how to backup/ restore GRUB. Having a backup is always very helpful in situations like these where a single OS overwrites the MBR or GRUB configuration. Learn how to back up GRUB @ the GRUB page.
I really hope this helps. If not, look around at forums, and see what others tell you to do. THE BEST THING TO DO IS TO TAKE EVERYTHING SLOWLY. DO NOT DO ANYTHING THAT YOU HAVE NOT THOUGHT THROUGH FIRST. YOU DON'T WANT TO LOOSE DATA.
Good luck, and fill me in on how everything goes! If you supply the specific OS's that you have on the rest of your disk(s), I may be able to help more. But this should give a good start.
Do you know anything about triple booting? i installed backtrack on a 3rd partition and it took over... no other os's bootedThe best thing to do in this case is reload GRUB, or add the other OS's to the boot loader from the OS currently running. The MBR or GRUB configuration was likely over written by the BackTrack installer. To get the other operating systems to boot, first try to find ways to add boot entries from your OS that can boot. There is often a tool present somewhere in the OS to et you do this. If not.... well then you will have to manually edit the menu.list file. Add the information for you operating system to this list, you will have to add something along the lines of :
title Ubuntu Edgy Eft
root (hd0,5)
kernel /vmlinuz root=/dev/hda6 ro quiet splash
initrd /initrd.img
savedefault
