Multi Rom :

Multi ROM is a multi-boot solution for several devices

It can boot any Android ROM as well as other systems like Ubuntu Touch, once they are ported to that device. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.
