I have a strange problem with my VDI based drive in VirtualBox, which is that the drive does not expand and this has for some reason also resulted in my x not being able to load.

df -H

Filesystem      Size  Used Avail Use% Mounted on

/dev/sda1       4.3G  4.3G     0 100% /

udev            1.1G  4.1k  1.1G   1% /dev

tmpfs           421M  750k  420M   1% /run

none            5.3M     0  5.3M   0% /run/lock

none            1.1G     0  1.1G   0% /run/shm

none            105M  8.2k  105M   1% /run/user

overflow        1.1M     0  1.1M   0% /tmp

And the drive size:

Is there a way for Ubuntu to reallocate its actual space?

By using GParted i simply copied the partition i wanted to resize and pasted it into the unallocated partition and resized it. It started copying the partition over and problem was solved.

Since i have already done this i am unable to viualize by screenshots, but there is an copy and paste function when you right click on a partition, so the procedure is simply:

Right click on the partition you wish to expand and click on Copy

Right click on the unallocated partition and click Paste.

A screen should popup where you can set the new size

GParted will start copying the partition into the new resized partition

Test the new partition before deleting the old one.

An image of the right click menu:

As you can see on the image above /dev/sda1 is the old partition that was too small. The new partition which i am booting from currently is /dev/sda3.

If you delete your old partition, you will need to install grub in the new one (no, it isn't copied together with your data). Boot with a live CD and run the following commands:

sudo mount /dev/sda3 /mnt  

sudo grub-install --root-directory=/mnt /dev/sda
