Remove dual boot 8.10/9.04

[borislevalle]

I had 8.10 on my computer, to my satisfaction. Since I have a troublesome VPN connection, I wanted to try Jaunty next to 8.10 before doing the final upgrade. I installed 9.04 next to 8.10, played around and got my internet connection to work.

Now I want to remove 9.04 so I can upgrade 8.10 to 9.04. How can I uninstall 9.04? To be sure: 8.10 shouldn't be removed of course. I am not running a Windows/Ubuntu dual boot, so there's nothing I can do via Windows. Also, I do not have separate partitions.
Thanks, Boris

P.S. Ever since I installed 9.04, my 8.10 boot list has become a lot longer. Is that normal?

Simply use Gparted in 8.10 to delete 9.04 partition (unmount it first). (You say you "do not have separate partitions," but you must if you installed them side-by-side, right?)

Then run


sudo grub-install /dev/sda

this will re-write stage1 to the mbr of the disk, pointing to your 8.10 / partition boot menu.

Excuse me for interrupting your thread borislevalle.

logos34, can you explain how to unmount the partition?

Thanks

[logos34]

sudo umount /dev/sdax

where x is 9.04 partition #

or right-click on it in gparted and unmount.

(If it's mounted, which it may not be)
