What do I do?

lol

dont use gentoo
use debian

preferbally ubuntu

but you apparently have some ****e dup disc

if you're asking yourself questions like that, i recommend you use ubuntu. it will help you get your feet wet in linux without the hassle. then as you learn about linux with it, you'll feel more ready to move on to distros like gentoo, or you may just continue to use ubuntu, since it's a very capable distro itself.

I recommend Microsoft windows xp.
