How to eliminate an old Ubuntu partition?

  • 772

I installed Ubuntu 12.04 64-bit side by side with my previous 11.10 32-bit.

As everything is working correctly, I want to eliminate the old partition.

According to update-grub:

Found Ubuntu 11.10 (11.10) on /dev/sda1

But according to GParted, /dev/sda1 is the boot partition!

So, how can I discover which partition should be the boot partition for 12.04? Can I safely eliminate the /dev/sda1?

Also, GParted gives /dev/sda5 as file system unknown, it's 2.93Gib and might be the swap partition (just guessing).

12.04

    Follow these procedures:

    1. Delete the /dev/sda1 partition from Gparted

    2. Create a new partition on /dev/sda1 from Gparted and also a new file system by formatting it.

    3. Open a terminal and type this command

       sudo grub-install /dev/sda

    4. Then run this command:

      sudo update-grub

    It should help you to get rid of that old partition.
