boot livecd/usb to a network connection, mount the gentoo partitions, enter the chroot, nominally: mount /dev/sdc3 /mnt/gentoo mount /dev/sdc1 /mnt/gentoo/boot cp -L /etc/resolv.conf /mnt/gentoo/etc/ mount -t proc none /mnt/gentoo/proc mount --rbind /sys /mnt/gentoo/sys mount --rbind /dev /mnt/gentoo/dev chroot /mnt/gentoo /bin/bash source /etc/profile export PS1="(chroot) $PS1" when done working in the chroot, make a graceful exit: exit cd umount -l /mnt/gentoo/dev{/shm,/pts,} umount -l /mnt/gentoo{/boot,/proc,sys,} reboot
