I recently had Mint 15 on my laptop but I wanted to upgrade so I just created a new partition and installed Mint 16 and copied all my documents. Then I decided I wanted to try Ubuntu 13.10 so I created another new partition and installed it there so I ended up with a Tri-boot system.
Then I deleted the Mint 15 partition, but it still shows up in the Grub menu. How do I delete it from the Grub menu?
Thanks in advance
