For reference, always follow: Gentoo Handbook.

Access the PC in any (Linux) way, like:

• Existing Linux distribution (mostly anyone will do)
• Burn Gentoo installation ISO to a CD or a USB key

Once inside, you will need to be root for all the subsequent steps.

Create a folder /mnt/gentoo:

 > mkdir /mnt/gentoo

Download Gentoo Stage 3 tarball from same link as installation ISO, then decompress it:

• From Gentoo boot ISO, you can use <b>links</b> from text mode.
• You will need to setup network, if not available. See the handbook above.

 > cd /mnt/gentoo
 >
 > tar xvfp stage3.blah-blah.tar.zy <-- note that the "p" is VERY important!

Prepare the chroot environment:

 > cp /etc/resolv.conf /mnt/gentoo/etc
 > modprobe efivarfs
 > for i in dev dev/pts sys run proc sys/firmware/efi/efivars; do mount /$i /mnt/gentoo/$i -o bind; done
 > chroot /mnt/gentoo /bin/bash
 > mkdir /boot 
 > mount /dev/sda1 /boot

Accept licenses, put this into <b>/etc/portage/make.conf</b>:

ACCEPT_LICENSE="-* @FREE @BINARY-REDISTRIBUTABLE @EULA"
