The best way to install Gentoo is to use have the manual up on one computer and then install Gentoo on the other
One can also mention using qemu and kqemu
to have a virtual installation runing within linux. So you can
still read the manual on a single pc
(Am saying that because sabayon supports it, and I suppose the
live cd of gentoo would as well).
I do not have vmware, but same would apply I imagine
if I ever deceieded to go Gentoo without going offical, I'd use Sabayon.
I can "confirm" this. I have been looking for a while into an
easy gentoo way to discover gentoo.
Taking the plunge in the next few days with Sabayon
(after quite a bit of reading, I decided this was my best option)
