I need to add unallocated space to my root ext4 partition where my Ubuntu 14.04 is installed.
I've read dozens of tutorials and couldn't find the one working for me.
Most of the tutorials include using the extended partition and moving space left to right or right to left. I don't really understand any of these terms and I'm not able to create an extended partition from my unallocated space.
If I click "Create new Partition" on my unallocated space, I'm only allowed to create it as a 'Primary Partition'.
It is also not possible to boot from live cd as I'm using Grub 2 that somehow does not allow me to boot from iso file and just gives me errors when I try to do so. I've already posted a question about this here and it seems there's no answer.
So, anyway, I need to extend my root partition when it is mounted (I've read that runtime extending can be done without losing the data).
Here's my GParted window screenshot:
My root partition is dev/sda8. It sometimes shows a mount point like on the picture (/,/var/lib/docker/aufs) and sometimes like this: / (don't really know why).
Could anyone please explain to me how I can add my unallocated space to the /dev/sda8 partition (in the most simple words possible, step-by-step for an absolute dummy in all this)?
PS: maybe it will be safer to extend my partition from Windows?
