Hi all, I'm having a very frustrating problem with a server and am in dire need of help.

All right, the situation goes like so: I took a snapshot of the virtual server. I then restored an earlier snapshot to try and troubleshoot a problem we were having. Well the earlier snapshot wouldn't boot, so I attempted to just restore the most recent and... it won't let me.

When I try to resture the snapshot, I get an error that goes along the lines of "Failed to restore Snapshot 2 of the virtual machine [computer name]" and "Parent ID (0000000-0000-0000-0000-0000000000) of the medium {path} does not match UUID {long string of characters} of its parent medium stored in the media registry {path}"

When I try to boot off of the current active snapshot, I get an error that litterally says "No Error Info" so currently the machine is non-bootable.

Now... please tell me there is some way to fix this and restore the recent snapshot. Also please don't tell me "Well, you should have..." because I didn't and I don't have a time machine and telling me what I should have done is not helpful and I shouldn't have to say this BUT I post a lot of help threads and this is what I typically get... Anyway, thank you in advance for any helpful replies!

Did you clone or otherwise manipulate the snapshot2 vdi in any way in the recent past? I ask because a parent UUID of all 0000s means that it isn't actually a snapshot, it's a stand alone VDI - which of course explains why attempts to manipulate it like a snapshot fail (at other times the VM will be perfectly happy). Cloning is the only way I know to turn a former snapshot into a stand alone VDI.

If it is indeed stand alone then clone it using CloneVDI, build a new VM around the new copy.

Yes, the parent is the original VDI, but the child snapshot is the one I want to restore. I will try cloning it. Thanks!

Ok, I can't clone the machine. I also count mount it in any program I try, or create a new VHD using the the old VHD as the drive.

The suggestion wasn't to clone the machine - obviously that can't work if the machine is inaccessible. The suggestion was to clone the disk only - and it's the snapshot you need to clone, not the base VHD.

All right, that's good advice, how would I go about cloning the disk only? Thank you kindly.
