Extending VHD / VHDX Volume

I have prepared the VHDX (or VHD in some cases) and it’s SYSPREP.  Now my C Drive is only 60GB but I would like to extend the hard disk to 100GB, to enable for me to install other applications on the C Drive.

I’m going to share how I do it.

My VHD is in the external drive (USB connected Hard Drive). 

Location E:\VHD\Demo. 

The VHD File is WIN81-ENT-x64-SYSPREP1.vhdx

I mount the drive to check on the space

As you can see it’s about 60GB. I’ll unmount and show the steps using DISKPART command

The command as follow :

• Open Command Prompt with Administrator rights
• Key in DISKPART
• Next key in Select the Disk of where your VHD is located. For me is located at E Drive.  Therefore I key in as select vdisk file=”E:\VHD\Demo\WIN81-Ent-x64-SYSPREP.vhdx” 
• Next to expand the TOTAL size of the VHD. I key in as expand vdisk maximum=100000
• Next key in attach vdisk
• Then key in list disk to view. If it’s not online then key on ONLINE DISK. It should be online automatically.

• Next key in list volume
• As you can see the volume shows as still 60GB
• I key in as select volume 6
• Key in extend
• Key in list volume to see the new size

• Opening up the attach disk, now it’s close to 100GB

Now I’m done, I would like to detach the VHD

Back to the DISKPART command prompt

• Key in detach vdisk
• Key in exit to quit diskpart from command prompt

In summary, I’ve keyed in as follow :

• DISKPART
• select vdisk file=”E:\VHD\Demo\WIN81-Ent-x64-SYSPREP.vhdx” 
• expand vdisk maximum=100000
• attach vdisk
• list disk
• list volume
• select volume 6
• extend
• list volume 
• detach vdisk
• exit 

Command in diskpart is in GREEN, you change those values in PINK 

Hopefully the steps are helpful.
