When Flashing New ROM onto Device, Can the Original Still Be Used?

Question

I've recently rooted my phone and I was thinking about adding a custom recovery and ROM. However, my original OS still must be accessed. Is this possible?

Answer

MultiROM should be what you're looking for, though it's only limited to a few of popular devices that support it / has it ported over, e.g. Nexus series, Redmi, etc. Look up in XDA-Developers if your device has a port.
