Than I open the .vmx file with VMware Server.

After this action the new machine is show in the inventory but I could not start it.

Should the machine working I used VMwareConverter to convert the machine to my ESX cluster

I think the correct way is:
Restore the machine image to a NTFS partition(the image was created with VCB + BackupExe12).

Than import the .vmx file to a VMware Server. Start the machine in VMware Server. At this point you have
to ways, first restore at file level or use Converter to import this machine in our ESX-Cluster.

My problem is that I can´t start this restored machine.

This problem machine has 2 volumes.

Other machines with just one volume I can successfully start.
