I'm really stuck with this and I can't understand why I sunddendly can't make ANY VM to start succesfully in my system.
I had just one VM, and it was working perfectly, then for some reasons I booted into another system, then came back into WinServer 2012 and couldn't make them start anymore.
This is the traceback:
PS C:\Users\Administrator> Start-VM Ubuntu
Start-VM : 'Ubuntu' could not initialize. (Virtual machine ID 1ECB1603-A320-4BAF-8452-9962768F5D49)
You do not have permission to perform the operation. Contact your administrator if you believe you should have
permission to perform this operation.
At line:1 char:1
+ Start-VM Ubuntu
+ ~~~~~~~~~~~~~~~
+ CategoryInfo : PermissionDenied: (Microsoft.HyperV.PowerShell.VMTask:VMTask) [Start-VM], Virtualization
OperationFailedException
+ FullyQualifiedErrorId : AccessDenied,Microsoft.HyperV.PowerShell.Commands.StartVMCommand
Seems clearly to be a permission issue of course, but I just don't get it, how?
I deleted my previous VM, not before I had it exported, THEN created a new VM, with new ID, using the same disk, same error above.
I even created a new one, without any disk, same error.
Does anyone know what could have happened?
Is there some script or configuration I should look for?
I've searched and searched even on msdn but nothing, I dont get it...
Any help would be greatly appreciated
Many Thanks in Advance!
EDIT
And, if I start it from HyperV's graphic interface, then it shows An error occurred while attempting to start the selected virtual machine(s) 'Ubuntu' could not initialize (Virtual machine ID 'ID')
SECOND EDIT
Following User @Peter Hahndorf suggestion, I ran icacls.exe and this is the output:
PS C:\Users\Public\Documents> icacls .\Hyper-V
.\Hyper-V BUILTIN\Administrators:(F)

It surely is about permissions, but how? I didn't "touch" anything, the folder is now placed under C:\Users\Public\Documents instead of C:\Users\Administrator\My Documents
How can I grant Administrator permission again?
