I would like to install Ubuntu, Lubuntu and Edubuntu all as if I were dual-booting, except I suppose it would become tri-booting. How should I go about doing this ? Are there any special steps involved other than simply installing them ? I install them via USB, by the way. I have also just tried dual-booting and Ubuntu, Lubuntu and Edubuntu all won't detect each other when I get to the Installation Type screen in the installation

  • Is this because you want to compare the versions in some manner? – Charles Green Jul 03 '14 at 15:11
  • Yes, that's right – Mr. Stark Jul 03 '14 at 15:16

    if you want to compare them the EASIEST method is to install 1 OS (your main) and then use VirtualBox to install the others. – Rinzwind Jul 03 '14 at 15:19
  • Aside from performance issues, it may be much easier to do this in virtual machines. – Charles Green Jul 03 '14 at 15:19

    @Rinzwind Great minds... – Charles Green Jul 03 '14 at 15:20
  • What would the hard method be ? – Mr. Stark Jul 03 '14 at 15:20
  • Getting them to do triple boot. I use VirtualBox (I use the Oracle PPA for this) and am running WinXP,7, 8.1, Android, and a test Ubuntu. While my main Ubuntu remains stable, I can play to my hearts content in the virtual machines. – Charles Green Jul 03 '14 at 15:22
  • The hard way: install all 3 in separate partitions. Well it is not that hard but grub needs to play nice from the get go ;) did it have windows 8 on it? if so: check BIOS and disable fast booting. – Rinzwind Jul 03 '14 at 15:24
  • It originally had Windows XP, but that's long gone. I have disabled fast booting a few minutes ago though and am trying it now – Mr. Stark Jul 03 '14 at 15:33
  • Would using Unetbootin to put the operating systems on flash drives be easier ? I simply used startup disk creator with iso files I got from the download sites – Mr. Stark Jul 03 '14 at 15:40
  • There is software out there that can just boot all three from a USB stick. http://www.pendrivelinux.com/tag/boot-multiple-isos-from-flash-drive/ – Richard Jul 03 '14 at 19:52

If they aren't automatically being detected, you may have to turn UEFI boot mode and/or Secure Boot off. When your computer first boots you should see an option to go into the UEFI and change these.

You may also select "Something else..." and manually set up your partitions.

  • I don't see anything about UEFI. At startup, the BIOS tells me F2 for setup and F12 for boot menu. I've already been to setup and saw nothing UEFI and the only boot menu option I haven't tried is Boot to Utility Partition – Mr. Stark Jul 03 '14 at 15:31
  • Okay, then manually setting up your partitions would be the way to go... see http://askubuntu.com/questions/343268/how-to-use-manual-partitioning-during-installation – Richard Jul 03 '14 at 16:10
  • What do I do if I'm running Ubuntu already, instead of windows or a blank disk like it is listed ? – Mr. Stark Jul 03 '14 at 16:36
  • Unless you can tell me how to make a blank disk – Mr. Stark Jul 03 '14 at 16:36
  • @Mr.Stark You can still access the "something else" menu, create three etx4 partitions for each system, and one swap partition of decent size. – Richard Jul 03 '14 at 16:50
  • Will all of them use the same swap partition then ? – Mr. Stark Jul 03 '14 at 16:53
  • I have 3 partitions made in ext4 format and one partition made in linux-swap format. When I press Install Now, a message pops up saying "No root file system is detected. Please correct this from the partitioning menu." – Mr. Stark Jul 03 '14 at 17:16
  • You have to select the desired partition and click "Change...", then make sure the mount point is simply /. – Richard Jul 03 '14 at 19:47
  • Should all the partitions be mounted at / – Mr. Stark Jul 03 '14 at 21:59
  • Just the one that you want to install on. Do this for each Ubuntu installation. – Richard Jul 03 '14 at 23:46

Just install them normally to separate partitions, they will automatically update grub to include all usable systems
