The loop of recreating a bootable USB drive for every reinstall or troubleshooting became unbearable for me. I switched to a Ventoy drive a long time back, and it's saved me so much time. Before that ...

I've got a 4 Gigabyte flash drive that I'd like to make bootable. For right now, I need it to boot DOS or DS linux. I'd like to have it boot to grub or something similar so I can select either one.
