Unraid 7.3 Beta: Convert Your Server to Internal Boot
Unraid 7.3 Beta is here, and with it comes one of the most requested features yet: internal boot. No more relying solely on a USB flash drive to run your server.
In this video, we take an existing Unraid server that's already set up and running, upgrade it to 7.3, and convert it from flash boot to internal boot. We'll cover how to safely clear data off a pool drive using mover, convert that drive into a boot pool through the onboarding wizard, move your data back, and transfer your license from the flash drive to TPM so you can remove the USB entirely.

This is beta software. Please test on non-production servers and report any bugs you find.
