Is it possible to extend the disk space available to a wubi install?
I have ubuntu 10.04 installed inside Windows 7 through Wubi. I need to increase the size of /root or root.disk. How can I do this? wubi-add-virtual-disk does not work since root.disk is already present.
Found this information on the wiki:
So, essentially you do need to create a new disk, move your data over to it (it seems like this script might do that for you, but I'm not completely sure) and then remove the backup image when you're satisfied.
