I installed Maverick in an old machine. I then decided to see if there is significant performance gain if I installed Lubuntu instead. So I created a dual boot with Lubuntu 10.04 in another partition for testing. Now I want to remove Lubuntu and give the whole hard disk back to Maverick
If I just delete Lubuntu with gparted (using a live usb) I think I would run into problems because I need to restore grub2 to maverick. I read about it briefly but forget how to do it (haven't done that before)
Please tell me what the proper procedure is. Thanks.
