Edit Not Available Because Checkpoints Exist For This VirtualMachine - HyperV Manager Not Showing CheckpointsIf you have a Microsoft HyperV Checkpoint / Snapshot that has come disconnected from the Hyper V Manager console, then you need to manually merge the VHDX and AVHDX files.   Fortunately, this not generally very difficult:

  1. Shut Down the VM in question – This is not technically required but it will be faster and will reduce the likelyhood of data loss
  2. How To Merge AVHDX When No Snapshots Appear in HyperV ManagerIn HYPER V MANAGER, click EDIT DISK from the actions pane on the right
  3. BROWSE to the .AVHDX file for your VM (not the .VHDX) and click NEXT
  4. Select MERGE and click NEXT
  5. Select TO THE PARENT VIRTUAL DISK and click NEXT then FINISH

If this fails with Failed To Merge The Virtual Disk 0x80070032 as shown in the screen shot to the right, go through the process again but this time select SOLVED: How To Merge AVHDX When No Checkpoints Appear in HyperV ManagerTO A NEW VIRTUAL HARD DISK at the end.  Once that is done, you will have to delete the old VM and recreate it pointing to this merged VHDX.  If you try to just change the VM’s SETTINGS > VIRTUAL HARD DISK to point to the new VHDX you will see it errors out with a MERGES PENDING message.

Remember that you can do all of this using PowerShell if you want.  See THIS Microsoft Merge VHDX article for details.

Try deleting the snapshots if they aren’t needed and once completed, that should start the merge process for the duplicate avhdx files.

Instead of completely deleting the old VM you can just remove the old hard drive pointing to the avhdx file and add a new hard drive pointing to the parent. You can do this both in 1 commit rather than removing, clicking apply and adding then click apply. For both IDE and SCSI disks I keep the drive ID the same, just in case the OS/BIOS boot isn’t reading disk labels.
