I ran out of space on a virtual disk for my exchange server so i expanded the size of the disk in hyper v and now the virtual server will not boot it gives the error:
The chain of virtual disks is corrupted. There is a is match in the virtual sizes of the parent virtual hard disk and differencing disk.
My VM is running exchange and has 2 virtual disks, one for the OS and one for exchange 2010. I accidentally expanded the vhd (the parent disk) and then did the second one. Now I get the above errors. I do not have a snapshot of the server or a backup.
