Yeah totally go with Ventoy. I had an external device that basically did the same thing but it was a pain in the ass. Little screen and you pick an iso on the drive and it simulated a CD rom. Ventoy is so much simpler. My only complaint is there isn’t an installer that works on a Mac so I have to use Windows. But other than that it’s awesome.
It must have gotten better than the last time I tried to use Ventoy. Maybe 5 years ago? It kept complaining that the USB drive I was using was bad when it worked completely fine with other tools.
