I have a strange problem about loading with grub2 and efi on gentoo. Maybe I've missed something, but I'm trying to do this:
# mkdir /media/gentoo
# mount /dev/sda8 /media/gentoo/
# mount -t proc none /media/gentoo/proc/
# mount --rbind /dev/ /media/gentoo/dev
# mount --rbind /sys/ /media/gentoo/sys/
# chroot /media/gentoo/ /bin/bash
# env-update
>>> Regenerating /etc/ld.so.cache...
# source /etc/profile
#
...
# parted -l

But after the reboot I see Window 8 loader again. How can I figure out, what's going wrong (any logs, or debug messages)? Or maybe you can see, that there is some stupid error? I've already asked this question on the gentoo forum, but maybe I'll have better luck here.
UPD: The option "Secure boot=Enabled" was a culprit.
