How to uninstall one of two dualboot operating systems

Asked by Ross Pine

I installed Ubuntu14.10 AND Linux Mint 17 on my acer laptop. How do I uninstall Linux Mint 17?
I think my computer should run better with only one OS.

You uninstall an operating system by removing the partition where this OS is stored.

What is the output of the following terminal commands:

uname -a
lsb_release -a
sudo fdisk -l
sudo update-grub

Thanks Manfred for the response. This looks far too complicated for me. I do not know how to find or remove the partition.
Following are the outputs of the commands that
 you suggested.
I find that I like ubuntu better than linux mint and was hoping to regain some disk space.
Thanks, Ross

The layout of your hard disk has the partition for Linux Mint in front of the partition for Ubuntu. So there is no easy way to remove the Mint partition and to extend to Ubuntu partition to the space that was used by Mint.

If you have not created much files or installed lots of additional applications, the easiest way to remove Mint and to provide all disk space to Ubuntu would most probably be a new installation of Ubuntu, using the whole disk.

Don't forget to create backup copies of all your important files to an external medium before you start changing anything on your disk layout.
