My computer can boot a CD… Can I boot the iso off of a floppy disk or a flash drive?
You can’t boot the iso off of a floppy drive, it would not fit, nor does Ark have floppy images. There is a way to boot the CD via a floppy disk, however. You can do this by getting a copy of FreeDOS. You can copy this image to a floppy disk using a program like rawrite for Windows or the follow command in Linux: dd if=fdos1440.img of=/dev/fd0 obs=128k using fdos1440.img and /dev/fd0 as placeholders for the file and the floppy drive, respectively. If you do not have a floppy drive and/or your computer supports booting from a USB drive, you can try the Installing from a USB memory stick section of the ArkWiki.
