[arch-general] Reconfiguring grub 2

[Csányi Pál]

Hi,

I just reverted my ParabolaGNUlinux into ArchLinux.
First, I set the Arch mirror list.
Then update the whole system:
# pacman -Syyu

Then replace the linux-libre kernel with 3.15.3-1-ARCH kernel.

Then reboot, but grub 2 want to boot system with linux-libre kernel.

I edited the grub entry so I can to boot the system with the new kernel.

But, how can I generate the new Grub config?

I tried followings:
# pacman -S grub
# grub-mkconfig -o /boot/grub/grub.cfg

Still, when reboot, I get the Grub menu es it was before, when did
using linux-libre kernel.

What must I do to solve this problem?
