Ok, I downloaded Ubuntu 13.10, for a eMachines G640 with 64-bit AMD-processor, making it dual-boot with Windows 7 with a USB not CD.

Didn't had problem installing it, booted nicely into Ubuntu but when I transferred some files from my 1TB External-HDD, to my PCs 320GB Hard-drive, I got the error message saying "there is only 103,3 GB space left" and told me to "delete some files to get more space".

What's the problem, and how do I fix it? is it the partition? the OS? My PC?

EDIT: Right, a friend of mine said it is the partition, and I should extend the Ubuntu Partition, because he says it's only 20GB out of the 320GB hard-drive, and he doesn't know how to do that. Help.

the partitions are set up like this.

Thanks, Dash_plus_Java for the instructions you gave me.

It really helped me out a lot. Hoof-pump /)

Can you add the output of this command to your question please? Open terminal and run sudo fdisk -l . This will show us how your system partitions are set up. – Paul Tanzini Nov 29 '13 at 22:21
so this is how your partitions are set up: sda1(Hidden Windows): 13Gb, sda2(Windows System): 100Mb, sda3(Windows 7): 269Gb, sda5(Ubuntu): 19Gb, sda6(Swap): 2Gb. sda4 just contains your Ubuntu partition and swap. It looks like you have about 20 Gb of space for Ubuntu on your computer. Did you set up the partitions manually? 20Gb is enough to run Ubuntu, but not enough to be copying over media files to it. – Paul Tanzini Nov 29 '13 at 22:53
You need to shrink the /dev/sda3 partition then extend the Ubuntu partition (/dev/sda5). See here for more info:… – minerz029 Nov 29 '13 at 22:59
what is the output of mount? – Braiam Nov 29 '13 at 23:03

Thank you for giving me some more information to work with Bent. If you want to give more space to Ubuntu than 20Gb you will have to shrink the size of your Windows 7 partition. This can ruin your Windows 7 install easily; so if you haven't already Back Up Your Files!

First, you want to be sure that you have enough unused space in Windows that you can shrink the partition without causing problems. In Windows open the explorer and check the properties of the C: drive. If the drive has enough unused space to give up then move to the next step. Otherwise, remove files until you have enough space.

Second, run a disk defragment on Windows. This will group up all the files so it will be easier to move them if they must be moved when resizing.

Third, boot up a Ubuntu live DvD/USB and run Gparted. This program will let you resize the partitions on your computer. Right click on the swap partition on the very right and select swap-off. This will let you work with the partitions.

Right click on the large Windows 7 partition and select resize. Subtract the space you wan to give to Ubuntu from this partition.

Right click on sda4 and select resize. drag it to the left so that there is no gap between partitions. Now resize sda5 (Ubuntu) and do the same.

Once everything is done click the green check mark to apply the operations.

Cross your fingers. If everything worked you should now have the extras space on Ubuntu.

I bet you have a massive hard drive (something about 1.5-2TB), and Ubuntu is simply calculating the percentage that is left in the filesystem (5-10%) and issue an alert because the space is exhausting. For now you can ignore the message (or ask to do not show it again). There isn't a way to "solve" it (I look up the dconf keys and the preference was nowhere to be found, maybe hard coded).
