I would like to note that prior to your virtual machine disk extension I recommend to back up the virtual disk. After that, the size of your partition will be increased. By default all available space will be offered to increase the disk size.

Select the partition you want to increase and click Extend Volume.

All of your disk partitions and unallocated space added will appear

Select Storage -> Disk Management in the left pane.

Open Server Manager -> Tools -> Computer Management.

I then used it to create a larger partition (30GB) and then used disk utility to restore the drive from that image. I decided to resize the disk, by creating an image of the disk, (in disk utility, and then used the boot camp utility to remove the partition. since the drive is only 120GB with 70GB free. When i created the partition, i set it for 15GB.
