disk management - How do I give Ubuntu more space (when installed inside Windows 7 (via wubi))?

I had installed Ubuntu inside Windows XP but then I formatted XP and installed Windows 7.

EDIT1: I used Wubi for the same.
I want to know which one of the two will solve my problem? creating a virtual disk or resizing root? Also is resizing root possible as the 4GB ext4 partition is already in a NTFS format Hard Drive partition.

At the time of installation I had allocated only 4GB of space to Ubuntu. I want to increase that size as I keep getting a low disk space notification.

I have surfed through a lot of similar questions but this is not a duplicate.

Because I want to know a little about the file systems. In order to solve my problem,do I have to increase the size of root.disk? Or will it be solved by creating a virtual disk?

Also I want to know the difference between creating a virtual disk and just increasing disk space of root.I'm new to Ubuntu so I don't know how the file systems function.

EDIT2:I have created a virtual disk of 10gb ,but I'm still getting the same notification.Is there anyway to install all further applications on the virtual disk I created?

Additional virtual disks are only useful if you're able to split the filesystem (eg putting /home/ on it) so aren't much use if you've installed a ton of stuff. You can split things like /usr/bin but it can get really messy, really fast.

Have you not seen a link to this post on your travels? You'll need a LiveCD or LiveUSB to action it, but it's very simple once you're at that point. Here are the main points:

• mount your windows partition (where the Wubi install sits)


• fsck the Wubi filesystem to make sure it's okay. If you don't do this and it has corruption in it before resizing, bad things can happen.


• resize2fs the Wubi filesystem to increase its size.


• Have a snack, chill out, high-five yourself... You've just increased the partition size.

Those aren't the full commands, I'll leave those in that thread because it seems to be well maintained.

Failing that, installing Ubuntu only takes a few minutes. If you like it, perhaps you should consider a proper install (disk performance is better too).
