[SOLVED] Grub Entry to boot via UUID

I'm trying to get my system booting by UUID but I am having issues with the grub entry as it won't boot. The following is the non uuid one that works:

# (2) Arch Linux

title  Arch Linux sda5

root   (hd0,4)

kernel /boot/vmlinuz-linux root=/dev/sda5 ro

initrd /boot/initramfs-linux.img

And below are the two that I have tried for uuid:

title  Arch Linux by UUID (sda5)

uuid   857136db-0356-46bd-9fff-0126b575218b

kernel /boot/vmlinuz-linux root=UUID=857136db-0356-46bd-9fff-0126b575218b

initrd /boot/initramfs-linux.img

and

title  Arch Linux by UUID (sda5)

uuid   857136db-0356-46bd-9fff-0126b575218b

kernel /boot/vmlinuz-linux root=/dev/disk/by-uuid/857136db-0356-46bd-9fff-0126b575218b

initrd /boot/initramfs-linux.img

Can someone point out which bit is wrong?

Thanks

Re: [SOLVED] Grub Entry to boot via UUID

Try:

title  Arch Linux by UUID (sda5)
kernel /boot/vmlinuz-linux root=/dev/disk/by-uuid/857136db-0356-46bd-9fff-0126b575218b
initrd /boot/initramfs-linux.img

You may need the root   (hd0,4) line as well.  I think that is required to tell Grub where to find it's intermediate files.  It would go in front of the kernel line.

Edit:  I assume, of course, that your UUID is correct   You might check that.

Re: [SOLVED] Grub Entry to boot via UUID

Yeah first thing I checked was that the uuid was correct.

You were correct and adding that line in got me up and running. Should've tried that first.
