I installed Backupmenu and it came with Bootmenu 1.12. I have NitDroid installed by the automated installer, but I'd rather not mess with multiboot as the last time I tried it it messed up with the kernels and I had to reflash the stock kernel (I later installed the power one). After reflashing and losing Multiboot I can't boot NitDroid anymore. I'd like to use the newly-installed Bootmenu to gain this ability back.

I understand all I need to do is add an .item file that'll boot NitDroid from the internal memory; I've Googled but I only found instructions to do so from a microSD, which involves creating partitions and whatnot.

How should I proceed?
