I have a virtual 2003 server that runs on win 7 virtual pc. Removed virtual machine additions. Rebooted several times to assure no problems booting. Server has been updated. Coppied vhd file to hyper-v server. Went throgh the wizard to create a virtual machine. When i try to connect,on boot I get "A disk read error has occured Press Ctrl+Alt+Del to restart". I run other VM's without issue. Hyper-v is windows 2008 r2 standard 64 bit.
