I am looking for what the best method would be to accomplish the following:
- Boot DOS 7.1
- Boot FreeDOS ISOs
Currently I manage a bootable USB key that uses DOS 7.1. Recently we've been given BIOS updates in the form of ISO files that work exclusively on FreeDOS. The USB key uses DOS 7.1 for program compatibility reasons and we can't just abandon it. I know there are a bunch of different methods to multiboot but I have no real experience with any of them. So I was hoping that there was a way I can retain the existing system and add the ability to alternatively choose to boot the FreeDOS ISOs.
I saw in the tutorials about booting WinPE based ISOs but I don't know if would be the same. Unfortunately I am unable to redistribute the FreeDOS ISO files.
Oh one more thing, I need a solution that allows for business use, as this isn't for personal/home use.
