Reading these comments I feel obliged to mention the Android app 'DriveDroid' which lets you store multiple disk images on your phone and then acts as a bootable USB disk. I've got GParted, CloneZilla, Alpine, Debian etc live disks always in my pocket. All I need is a micro-usb cable (which most modern homes seem to have laying around) to boot into various OSs and tools.

No affiliation, I just think it's a cool free app and it's proven very handy for me loads of times.

That sounds super useful! I wish it was free software and available in F-Droid though. Looks like the normal version even has ads.

Never heard of it, but it sounds really usable.

Thanks for the tip!
