I've Win8/Ubuntu Dual boot. I already have 4 partition so i cannot create a new partition and mount it elsewhere. So, this (How can I increase a partition's size?) question did not help.
Here's a screen shot of my Gparted (run on Ubuntu Live)
How can I extend
/dev/sda6 so that i can make use of unallocated space ?
(w/o failing my current grub)
