Hi chipsnblip
Yes u possible can do it with that d3scription in ur link. I'm wondering if anyone has successfully burnt a big gig pi image with games and boxart tge lot onto an external drive and it worked.

I've been chatting around on forums for past few weeks and talking about this and alot of people have said no u can't boot the image off ex hdd u need a 64gb 128gb or 250gb sd card. As it's not possible to run it off external.

Just done it myself in about 5 simple steps. With help and info from Internet of course

Just wondering as I've made my own image with games art and stuff put it on external and plugged into pi and powered on and it booted up and works.

Has anyone else tried it instead of going the long way round and inputting lots of data into the pi terminal to format scan re partition and to auto mount the usb drive.
