expanding .disk file

[Jeroen De Dauw]

I installed Kubuntu 10.04 a while back from Windows on an 150GiB NTFS partition. The Kubuntu (EXT4 I guess) filesystem is only 30 Gib big, and is located at
D:\ubuntu\disks\root.disk in Windows. Obviously I want to use the whole 150 GiB of my partition, and I also don't want to re-install and lose my current Kubuntu setup. So how do I fix this?

If you are liking Ubuntu, you should consider converting to a full install.

Agostino: Wubi actually wasn’t designed to do long-term installations. The main aim was really to let people try out Ubuntu with confidence. Normally, users that start with Wubi tend to upgrade to a full installation to a dedicated partition at the next release cycle.

You can copy all your /home into the new install. And you can make a list of all installed applications to reinstall in your new install.
