Triple boot?

post #1 of 6
Thread Starter 
Ok, I have been playing around with flash drive distros for a while now and am ready to dive into the real thing. I want to install Ubuntu and triple boot it with my current XP and Vista installs. Just a few questions first. Will Ubuntu overwrite the vista boot loader with grub? I would kind of like to keep the Vista boot loader (yes, I am still somewhat in the grasp of M$), and just have Ubuntu boot from that. Is this possible? Also, I plan to install it on my 1TB drive (not my RAID array). Do I have to make one partition or two? I plan to have about 50GB for Ubuntu, but I heard that I have to have a 1GB partition as well? Thanks for any help! I don't want to screw up my Vista or XP installs.

AFAIK it does not, but that's something someone is going to have to verify... I dualbooted XP + Ubuntu, had Ubuntu installed on a different HD and while groub recognized my XP installation and allowed me to boot it, my XP drive was not affected in any way... if possible, I would recommend having Ubuntu on a separate HD, if you do this just make sure that the Linux HD is set as primary in BIOS so the boot loader will be installed on it (though you can manually specify which drive to install it on, it is an "advanced option" and not the type of thing a user migrating to Linux will want to mess around with).

Windows boot loader can't boot Linux, Linux uses Windows-incompatible file systems (ext3) and AFAIk even if you decide to install Ubuntu on NTFS or FAT32 partition (certainly not recommended), it probably can't do it.

Right, so assuming that you have Windows on this RAID array, as I said before all you need to do is set the 1TB disc as primary and install Ubuntu, the windows partition/bootlooader or the RAID array won't even be touched.

Do I have to make one partition or two?
One will suffice, but it's a common practice to have '/' and '/home' as two separate partitions - makes distro upgrades easier since you don't lose any of your setttings, and even if you decide to try another distro altogether your documents will stay.

That 1GB partition would probably be the swap partition, with 4GB RAM you won't even need it (just make sure you have the 64-bit version, it also performs faster than the 32-bit version). I had Ubuntu on a rig with 2.5GBs of RAM, never saw it go even beyond 700MB even when gamin, Compiz enables & several other apps open (inclluding firefox with multiple tabs). Ubuntu will warn you about the swap partition should you choose not to create one; you can just ignore it, 4GB is more than plenty for Linux.

You should be presented an option to install using LVM during the partitioning section of the installer. If you don't see this, stop and install Ubuntu using the "alternate CD" instead. This will solve your problems with possibly needing a swap partition, separating / and /home, running out of available partitions on the drive, etc.

Make sure you hit the Advanced button during the Ubuntu installation to change the grub options to install it to Ubuntu's boot partition instead of the MBR. Then later you can add an entry to Windows boot loader to boot that partition. (Ask someone else how. I'm not touching that piece of :turd: excuse for a boot loader.)

I'm pretty sure you can use EasyBCD to rewrite Vista's bootldr back in.

Ok, thanks for the replies. One more thing, if I install Ubuntu on my 1TB drive (currently used just for data, no OSes) and my RAID0 dies (it has my Vista/XP installs on it) will I still be able to boot into Ubuntu? I will do what error10 said, and install grub to the Ubuntu boot partition.

Only if you boot from that drive.
