I've created a partition of 50GB to my Ubuntu on my SSD (using Win10 with 200GB), I want to expand my Ubuntu's space by say, 20GB. So I've de-allocated that space from my /sda2 (ntfs) partition.
Now I would like to merge the unallocated space with /dev/sda5 which is an extended partition.
I've tried using AOEI software on win10 but it said it doesn't take care of extended paritions. Tried to unmount sda5 (with --force or -f too, and with -l too), and it just made my system laggy, couldn't do anything and had to restart, and eventually the key stayed.
I guess the steps should be to unlock the extended parition and then move the unallocated space down, and then I would be able to extend my Ubuntu's space, but I'm not able to do it.
