Getting UEFI to play nice
i had a issue with uefi and grub2 today, found out a realy simple solution
boot into a live cd (uefi mode)
mount /dev/sda1 /boot
grub-install --target=x86_64-efi --efi-directory=/boot/ --bootloader-id=grub --recheck --debug
grub-mkconfig -o /boot/grub/grub.cfg
found some of the info @ slackware docs
