Hi Support,

I tried to delete a Hyper-V check point in Hyper-V Manager but failed with an error. However I can create checkpoint without problem. Currently the disk is 14.6GB free of 97.6GB. I have two vm running, i can successfully delete checkpoint for the other vm. Please advise how to fix this problem. 

The hosting machine OS is Win 8.1 Enterprise 64bit. 

Error message in Windows-Hyper-V-VMMS-Admin:

'xxxxx' failed to remove checkpoint. (Virtual machine ID 9405BED8-CF63-4497-AD27-0A4F4E01BB06)

Virtual machine failed to generate VHD tree: 'Catastrophic failure'('0x8000FFFF').

Cannot delete checkpoint: Catastrophic failure (0x8000FFFF). Checkpoint ID A28B861B-3F04-41AC-82F5-EABB310DDC91.

Hi fishchips,

I want to ensure that you can not delete a snapshot even if it is created just now .

Also please inspect the disk "chain" (inspect disk in vm settings ).

As a workaround please try to take a snapshost and right click the snapshot then export the snapshot .

After this import virtual machine from the exported files .
