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

well, i got into my usb system by using the "rd=diskXsY" boot flag.

but now i think i kind of invalidated my "com.apple.Boot.plist"...
i tried to insert the flag via terminal but copied afterwards between the two installs.
for achieving this i had to set permissions for the folder (in finder).
now the .plist no longer shows the plist icon and i assume it is not loaded as the rd= flag
does not work automatically.

any ideas how to fix the .plist (why the need to use sudo nano in the first place anyway?)

edit:

adding flag to .plist worked (using nano), i got 2 seperate installs now.
setting startup volume in sys config does not work...
