Need to resize Ubuntu partition under VirtualBox. As per other posts, have resized VirtualBox from 8GB to 16GB. Have booted Ubuntu 16.04.1 from DVD.
I started gparted and see four partitions:
/dev/sda1 [ext4] which is 7.5GB [this is the partition I want to enlarge],
/dev/sda2 [extended] which is 510MB,
/dev/sda5 [linux-swap] which is 510MB,
followed by unallocated 8GB.
Unfortunately, selecting the sda1 partition and attempting Resize/Move shows no chance to enlarge. Selecting the sda2 partition and attempting Resize/Move does show the ability to consume the unallocated space, but this is not the partition I want to enlarge. Ditto swap.
How to get gparted to enlarge the sda1 partition? Thanks. GParted screenshot
