    An error occured while attempting to start the selected virtual machines

    "...." failed to start

    Microsoft Emulated IDE controller (instance ID -[propert......avhd" . error: 'The chain of virtual hard disk is inaccessible. ehter was an error opening a virtual hard disk further up the chain.

    Failed to open virtual disk

    'D:\VMs\prop\prop\.... avhd' . A problem encountered opening a virtual disk in the chain of differencing disks, the size of the virtual hard disk is not valid

    Did you expand the base VHD when you had snapshots of it?

    If so, I don't think there are any recovery options -- you should have merged the snapshots first

      it actually looks like he's uisng Differencing Disks - ie, it writes the differences to a separate disk. Which, I guess is sort of like snapshotting..

      I'm with ossian - hope it wasn't a prod. server

        It was the AVHD reference that I took to be snapshots -- which are a form of differencing disk anyway

        Lets wait for more information, although if it was a production server, it would obviously be fully backed up so restoration would be a doddle
