I have 4 OSes installed:
Windows XP on sda1 Backtrack on sda5-6 Ubuntu 11.04 on sda7-8 Ubuntu 10.10 on sda9-10
I want to remove Ubuntu 11.04 (partitions sda7-8). I tried using GParted from Ubuntu 10.10, but it says that I have to unmount logical partitions with a number higher than the one being removed.
What can I do?
