Hi community

I've some backup of Vmware VMs with Backup Exec 2012 Appliance, now i need to restore in another different server, the restore process finish sucesfully, but when i power on the Vm i obtain the message error "Operating System not found" .

These are my scenario:

The VM Source ESXi 5.5.0) is in Vshpere 5.5 

Operating System: Windows Server 2012 R2

2 partitions ( C: et D:) In different datastore

Array Controller : HP Smart Array B320i RAID Controller

The Destination VM is:

ESXi 5.5.0, 

I've only one datastore

Array Controller : HP Smart Array B320i RAID Controller

I need to restore about 10 VMs with the same settings and i've the same message

Thanks
