cloning fails, wrong startup volume

[zuz242]

at first i installed leo on an external usb drive. then i copied the patition internal with acronis.

now i got this problem: i cant boot the external install. i can choose the hd via bios boot menue,
darwin bootloader starts but loads into the wrong system. i tried to switch the startup volume in
sys config, but there are no partitons to choose from. (only network boot)

how do i get a running backup system?

thanks
