(SOLVED) Grub2 won't boot lvm on gpt

Question

When i try to boot arch the grub screen comes up for a second and then my computer restarts. I followed this tutorial to the letter: http://www.youtube.com/watch?v=69X9ZYA41xU
I've been at this for a couple days with no luck.
Thanks

Answer 1

Well i managed to get arch to boot by editing the /boot/grub/grub.cfg directly. For some reason, running the command grub-mkconfig -o /boot/grub/grub.cfg
and grub-install won't update anything from my /etc/default/grub file or anything from my /etc/grub.d folder. What i have to do:
grub-mkconfig > /boot/grub/grub.cfg
Then append my menu entries
# DO NOT EDIT THIS FILE
# It is automatically generated by grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
### BEGIN /etc/grub.d/00_header ###
insmod part_gpt
insmod part_msdos
if [ -s $prefix/grubenv ]; then
load_env
fi
set default="0"
if [ "${prev_saved_entry}" ]; then
set saved_entry="${prev_saved_entry}"
save_env saved_entry
set prev_saved_entry=
save_env prev_saved_entry
set boot_once=true
fi
function savedefault {
if [ -z "${boot_once}" ]; then
saved_entry="${chosen}"
save_env saved_entry
fi
function load_video {
insmod vbe
insmod vga
insmod video_bochs
insmod video_cirrus
set menu_color_normal=light-blue/black
set menu_color_highlight=light-cyan/blue
insmod part_gpt
insmod lvm
insmod ext2
set root='lvm/arch-rooti'
menuentry "Arch Linux 3.2.2-1 [Primary]" {
insmod lvm
insmod ext2
insmod part_gpt
set root=(arch-boot)
linux /vmlinuz-linux root=/dev/arch/root vga=795 ro
initrd /initramfs-linux.img
menuentry "Arch Linux 3.2.2-1 [Recovery]" {
insmod lvm
insmod ext2
insmod part_gpt
set root=(arch-boot)
linux /vmlinuz-linux root=/dev/arch/root ro
initrd /initramfs-linux-fallback.img
This does work  but i lose a lot of functionality
