Remove OS from Linux Dual-Boot

Question

I'm currently dual-booting two Linux-based operating systems on my laptop, Jolicloud and Ubuntu 10.10. How do I remove Jolicloud completely?

Answer 1

Theoretically all you have to do is

1. Backup to at least 7 1/2 armored and padlocked locations around the world, in at least 6 different continents and pray to the unicorns that your data loves you.
2. Boot into Ubuntu and run gparted and delete the Jolicloud partition.
3. Apply changes.
4. Run sudo update-grub and reboot.

Which sounds way too easy. But should work.

Answer 2

Remove it from /boot/grub/menu.lst and use gpartd to delete the partition and re-create it as something else.
