Resize the VHDX file

The following process changes the VHD file size using the power shell (run as administrator).

1. mount-vhd <vhdname> –passthru | get-disk | get-partition | get-volume
• This will mount the virtual hard disk in the management operating system, and let you know the drive letter that was assigned to it.
• Ex: mount-vhd F:\MYVHD.vhdx –passthru | get-disk | get-partition | get-volume
2. resize-partition –driveletter <driveletter> –size <newsize>
• This will resize the partition inside the virtual hard disk.
• Ex: resize-partition –driveletter I –size 60GB
3. dismount-vhd <vhdname>
• Dismount the virtual hard disk after shrinking the partition.
• EX: dismount-vhd F:\MYVHD.vhdx
4. resize-vhd <vhdname> –ToMinimumSize
• Now shrink the virtual hard disk to match the new size
• EX: resize-vhd F:\MYVHD.vhdx –ToMinimumSize
