Ubuntu – Increase partition size on which Ubuntu is installed

The official Wubi page lists 2 options:

• Using LVPM (but the site states that it wouldn't work with 10.04, so I guess it won't work with 10.10)
• Moving your /home to a new virtual disk using the wubi-add-virtual-disk script. You can install if from the Wubi page.

I would suggest using the second option. Note that it will move your /home to another virtual disk, if you were short on space in another folder you might have to move that folder instead of /home.

You expanded the disk, but you still need to expand the partition and filesystem. Here's one way to do it:

1. Boot the VM with a live CD ISO.
2. Run GParted.
3. Expand /dev/sda2 and /dev/sda5 as big as they'll go.
4. Apply changes.
5. Remove the live CD ISO and reboot into the system.

Instead of using GParted, you can also use fdisk, pvresize, lvresize, and resize2fs (in that order) to manually resize everything.
