Thema: LX3 - multoboot plugin not working - bootloop

Hi,
I'm trying to prepare multiboot system on my LX3 with OpenATV and multiboot plugin, which appeared in downloadable plugins few days ago (AFAIR 1.0.0.5 ver).
Unfortunately whatever img i would try to install on usb stick using it, effect is still this same: new img appearing in multiboot menu, but after choosing it, it starting to load and after reaching 33% it starts continously restarting and booting.
Any tips how to make it work?

Best regards,
chrisjan

Do u have the internal HDD installed ?
