I have a dilemma and I don't know what to do.

Currently I have Ubuntu 14.04 64 bit installed along side Windows 7 64 bit and everything works wonderfully.

I recently started a course about Assembly on Linux and the professor recommended downloading Ubuntu 12.04 32 bit.

I downloaded the iso file and loaded it on to a USB.

When I first installed Ubuntu 14.04, it gave me the following 3 options:

1) install Ubuntu alongside Windows 2) delete Window and install Ubuntu 3) Something Else

I choose the first option. However, when I attempted to install Ubuntu 12.04 32bit along side Ubuntu 14.04 64 Bit and Windows 64 bit, the first option was gone. Instead I was given the following 3 options:

1) Delete 14.04 and install 12.04 in its place 2) Delete both 14.04 and Windows 7 and install 12.04 as replacement 3) Something Else

My question is this: is it advisable to install Ubuntu 12.04 32 bit along side Ubuntu 14.04 64 bit and Windows 7 as the Ubuntu Installer no longer gives me this option? Should I just go ahead and replace 14.04 with 12.04 for the duration of time that I would need it. I don't want to delete 14.04 but I will if need be. I also like the current Dual boot option Ubuntu has put in place so if making a 4th partition through way of "Something Else" would delete that, I would much rather delete 14.04 to make room for 12.04. Again my preference would be to have Ubuntu 12.04 32 bit appear alongside Ubuntu 14.04 64 bit and Windows 7 when I boot my computer, but short of that, I would settle for Ubuntu 12.04 32 bit appearing alongside Windows 7 for the time being. I look forward to your advice.

  • Th installer is only configured to auto setup dualboots. If you want to start adding OS's you'll have to choose "Something Else" from the 12.04 Live CD and manually configure your partitions. A basic config would be: create a drive (ext4, the size you want Ubuntu to be) and Set it be used as / Though, it would be worth it to read through some of the other partitioning posts. – amanthethy Jul 25 '14 at 20:21
  • Amanthethy, thank you for your advice. I'll look into your second post asap. – user309190 Jul 25 '14 at 20:31

    This one covers pretty much any scenario. In the example he creates a separate partition for the Home directory. The advantage there is that your system files would be independent from your personal files, and you could share your personal files between different Linux installs. If you don't need this create the / and the swap only/ That way your OS and personal files get installed to the same partition (which is the default install behavior)

  • If you just want a temporary system for one piece of software it is much more convenient to use a VM in VirtualBox. – bain Jul 25 '14 at 21:08

As @bodhi.zazen said installing different versions of Ubuntu/Kubuntu/Windows/whatever is fine. Most Linux distributions also install the GRUB bootloader so your dual boot will (functionally) stay the same no matter what you install.

How to install Ubuntu alongside the other version:

  • Select the Something else option and click Next
  • The partition manager will open:
    Partition manager
  • Select the partition you want to resize (ideally the one with the most free space)
  • Click on the Change... button (Ändern... in the screenshot)
    • The partition editing dialog will open:
      Patition edting dialog
    • Enter the new size for that partiton next to the New size in Megabytes text
      (Neue Paritionsgröße in Megabyte in the screenshot)
    • DO NOT TOUCH THE REMAINING OPTIONS! (Unless you know what you are doing...)
    • Confirm by clicking OK
  • The partition manager will now show some free space
  • Select the free space and click Add... (Hinzufügen... in the screenshot)
    • The Create partition dialog will open:
      Partion creating dialog
    • DO NOT CHANGE ANY OPTIONS! (Unless you know what you are doing...)
    • Close the dialog by clicking OK
  • Review the new partition dialog and click Install now
    (Jetzt installieren in the screenshot)

You can install as many versions of Ubuntu (or other versions of Linux) as you wish, limited only by hard drive space. grub or your bios will allow you to select an os to boot.

Grub will be able to select as many OS systems in your drive. However, the option you will have to use will be option "3".

However, if you had Windows before and did not resize the partitions, that can be a problem. What you need is space in your hard drive for the new ubuntu partition. If you see http://lifehacker.com/5403100/dual-boot-windows-7-and-ubuntu-in-perfect-harmony in the section "(Only) If Windows is already installed:" you will need to "shrink the partition" (Allocate at least 5 GB for the new Ubuntu partition).

When you try to do the installation again, go to "something else" and you should see free space where you can install the extra ubuntu partition (Please see How to use manual partitioning during installation?.)
