Before chrooting, I do (mind you, this is from a livecd environment) vgscan vgchange -ay mount /dev/lv/ide /mnt/gentoo mount /dev/hde7 /mnt/gentoo/boot mount -t proc proc /mnt/gentoo/proc chroot /mnt/gentoo /bin/bash (where /mnt/gentoo is the root of the to be installed linux system) If that isn't the right thing to do, then how do I do it right ? Many thanx already, hope I can get some more help. best regards Mark <--- previous mail follows from on here ---> "Heinz J .
