GRUB_TIMEOUT not working

Hi


I often install other linux systems on this laptop and found after one installation grub failed to show. So I believed I had a corrupted mbr.

So this is what I have done:

I used gparted to clear sda1 by formatting it as fat16 and setting the boot flag.

I deleted all /etc/default/grub.* files and removed /etc/grub.d/.* and /boot/grub/.* to start again.

I used the following command to erase the mbr. # dd if=/dev/zero of=/dev/sda bs=446 count=1

Then:

Code:
# pacman -R grub     
# pacman -S grub     
# grub-install --target=i386-pc /dev/sda
# grub-mkconfig -o /boot/grub/grub.cfg

Ok the grub menu shows on bootup. But even though GRUB_TIMEOUT=5 in /etc/default/grub the menu very briefly flashes onto the screen and immediatly starts to boot into the

GRUB_DEFAULT system which is arch.



/etc/default/grub

Code:
.....................# GRUB boot loader configuration

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="quiet"

I have just cleaned out the keyboard (again) this time given the laptop a thump and low and behold on the first reboot grub worked

It is an older laptop so so it will probably play up again.
