1. I ran VHDResizer going from 3GB to 4GB.
2. Did a "vhdmount /m /f <path> v".
3. Ran diskpart, selected the disk, selected the partition, extend, exit.
4. Ran "vhdmount /u all" then renamed the old and new .vhd's.

When I tried to start the VM, I got the "NTLDR is missing...press Ctrl-Alt-Del to restart" error. This is on MS Virtual Server 2005 R2 SP1. Is VHDResizer not compatible, or is there some other problem?

 Thanks, John.
