How do you generate a USB stick manually? What does that even mean?

UNetbootin only works with some distros, it is not a universal solution
like hybrid ISOs. IMO it is redundant now we have hybrid ISOs and in my
experience, very few distros are not hybrid nowadays. So forget
Unetbootin.

Because they create the stick in different ways, and there are several
different types of USB device to emulate when doing so. If the only ISO
that will boot from your computer on a USB stick is System Rescue Cd, use
that. It's one of the best distros for installing Gentoo anyway.
