some time ago I installed 12.04 from windows xp on a separate "linux" partition via wubi. this partition was allocated 50 GB. my problem now is that obviously the root directory does not have access to the entire volume but only to about 10 gigs which is now not very far from being exhausted.

when I call partition monitor I get this:

the hard drive is divided into 3 partitions altogether: the windows volume (sda1) with 146 gigs, a "save" volume (sda6) for backups and stuff with some 103 gigs and the linux volume (sda5) with about 50 gigs of space however being host of this strange subdivision "loop0" where the root directory seems to be placed (so this 10 gigs of the loop0 division seem to belong to the sda5 partition, at least thats what I get)

my question is: how can I make the ubuntu root directory to have access to the full 50 gigs of the partition instead of being restricted to the loop0 subdivision

to give you some more info heres what the df and mount comments tell me:

knabbits@ubuntu:~$ df -h

as you can notice I yet dont know much bout linux file structure but still thats the issues that make you want to understand it.


See this question about how to free up space in your /dev/loop0 partition. Then, consider migrating your WUBI install to an ordinary system.
