I want to install Ubuntu 12.04 and 14.04 on the same drive.

I have already installed Ubuntu 12.04 and I have manually partitioned the drive.

300 MB boot; 20 GB root; 400 GB Home; 5GB Swap

500 GB is unpartitoned. (left for 14.04)

Now I want to install 14.04. How do i go about partitioning the remaining 500 GB for 14.04.

I will create another Home and root partition, but do I also have to create another boot partition? I don't want to have any grub issues. I just want both the installation to be separate and neat.

  • You do not need to create another boot partition. During install of 14.04 you have the option of installing alongside 12.04 Aug 31, 2014 at 12:47
  • I actually didn't want to do alongside installation and do it manually. Thanks for the help though. Sep 3, 2014 at 4:07

I have found a better way to do this. I have partitioned the drive as follows.

ext4 - 25GB; ext4 - 25GB; swap - 4GB; ext4 - remaining [to be used to store data]

So now I have 2 operating system in the 25gb partitions and use the data partition as a common data drive. I have written a complete tutorial if anyone is interested.
