I use Ventoy[0] for this purpose (multi boot drives). With it you only have to format the drive once. Ten you just copy .iso images to the drive as files and they become available to boot from. It's great.

Nice software. Pity the hosting is so slow (I remember 2400 baud, and it's not that slow, but in the modern world it's slow); wonder if the author accepts donations to make it faster.

That said, the SystemRescue download from sourceforge was slower.. ended up finding a torrent and checking the SHA.

Seconded. It just works.
