I made a miscalculation on my Ubuntu install and now need more space for my Windows (NTFS) partition (sda2). The problem is that I allocated ~ 100GiB to what I thought would be a shared media storage directory; this was placed in an extended partition (sda4), comprised of ~ 7GiB in a swap file (sda5) and ~ 100GiB in an ext4 storage partition (sda6), respectively. I no longer require this partitioning and am now looking to allocate this sda6 space more judiciously.
As I understand it, I need to be able to have unallocated space in a partition next to the partition that I would like to add space to. There I have a problem, as I need to move ~55GiB from sda6 (ext4) to sda2 (NTFS). Please note that sda1 is a small NTFS Windows boot partition and sda3 is my ext4 Ubuntu install partition that does not have any unallocated space (at present), and only 22GiB unused.
Lastly, I am presently in GParted off of a USB boot and have a pending operation of shrinking /dev/sda6/ from 99.96GiB to 44.18GiB, but alas, I cannot add to sda2 as was my intention. I have backed up my system, though I would prefer not to undertake anything with a large probability of file loss or grub2 failure. May I please have any relevant recommendations? Thanks so much in advance.
