Unable to resize VHDX on Hyper-v 2016 guest

First of sorry if this is in the wrong section.

 

I had a 30GB Dynamically expanding volume that was causing me space issues. So i converted it to a "fixed" 60gb volume and the VM booted as expected.

 

The volume is still 30GB, but in disk manager (on the VM) i can see the extra un-allocated 30GB space. I wanted to "expand" the partition of the c:, but i can't as its a "boot" volume.

 

Any ideas? I wasn't expecting it to be so much of an issue.

 

cheers all.

You can expand a boot volume as long as there are no other drive letters using the virtual disk. I.e if you only have a C drive you should be able to expand the C Drive, if you have a C, D, E drives on the same virtual disk then you won't be able to extend the volume. Have you tried using diskpart?

 

Run a CMD prompt:

Diskpart

List Volume

Select volume X (where X is the volume number of the C drive)

Extend

 

^^ that should extend the volume to use up all unallocated space on the virtual disk.
