How to remove the dual boot option

Post by timbow » Sun Sep 16, 2018 6:18 am

I installed mint 19 alongside mint 18. so I have a dual boot and separate partiions. After a few weeks I am happy with mint19 and I want to remove the dual boot option and reclaim the old partition, deleting mint 18 and the old home folder.

What's the procedure for doing that?

I would
  • install GParted,
  • make very sure that I know in which partition the OS I want to keep is installed, and then
  • use GParted to delete the old partitions and set up new ones.

Thanks. GRUB will just look after itself then?

True but no reason to be too worried, you won't be able to unmount your / root partition while booted from it so you cannot really mess that up.

That said, if you want to resize your partitions currently in use as part of your plan to reclaim the space you'd have to do that from a live USB, in which case the above becomes very good advice again. ;)

But you do not necessarily need to change anything about your partition layout, you could just format that ones from the other OS and use them to store your data instead.

You don't need GParted by the way, you can do all of this via the built-in Disks tool available from the Mint menu.

Either way, after deleting or formatting the partitions, just run

Code: Select all

sudo update-grub
to update the boot menu.
