Dual booting Jaunty & karmic (how to remove Karmic & give the space back to jaunty

[dj-toonz]

Hi all, Just found out by my mistake after dual booting Jaunty & karmic (while installing Karmic) that the 3G HSDPA modem bug hasn't been fixed yet :( & can't update or even use the internet under the Karmic Partition (only Jaunty) so what I want to do is totally remove Karmic from the laptop & go back to single booting Jaunty. How do I do it & give the space back to Jaunty after removing Karmic & put grub back to normal ? cheers

Insert liveCD, not 9.10, - once at the desktop, start gparted from System>>Administration>>Partition Editor, right-click your Karmic partition(s), unmount them, then choose delete from the menu, then right-click your 9.04 partition, unmount, then select resize, in the pop-up menu resize, then click apply.
