[SOLVED]Cant find my ubuntu kernel

So I installed Arch on my comp last night as an Ubuntu/Arch dual boot setup.  Ubuntu is on sda1 and Arch is on sda3.  I mounted the Ubuntu partition from Arch and copied Ubuntu's /grub/menu.lst to Arch's but for some reason whenever I try to boot Ubuntu from Arch's grub I keep getting the error that /dev/disk/by-uuid/######### does not exist.

From what I understand, grub is looking for Ubuntu's kernel but cant find it where I specified.  Can anyone help me? My computer is a very essential possession of mine and I really need it up and running again soon!

Re: [SOLVED]Cant find my ubuntu kernel

Did you shrink your Ubuntu to install Arch?  If so the UUID for that partition is now different.  You can find out what the new UUID is by booting into arch and doing an

ls -l /dev/disk/by-uuid
total 0
lrwxrwxrwx 1 root root 10 2009-03-08 20:42 0c98c784-a797-4795-ba6e-d7c4ff8f7aa3 -> ../../sda6
lrwxrwxrwx 1 root root 10 2009-03-08 20:42 38cecaf3-3322-4606-85e2-3921e89bae9d -> ../../sda2
lrwxrwxrwx 1 root root 10 2009-03-08 20:42 7ee098fd-53e3-4c60-b565-a08e1fd213d5 -> ../../sda1
lrwxrwxrwx 1 root root 10 2009-03-08 20:42 ad0b2784-dc92-4567-afef-bb64e16933ca -> ../../sda7
lrwxrwxrwx 1 root root 10 2009-03-08 20:42 f9884b2a-b4d6-4ac8-bbc8-1b0a36b9f802 -> ../../sda5

This (on your system) will tell you what you need to change the UUID to in your menu.lst and Ubuntu's /etc/fstab

Thanks for the reply! I checked out the uuid I had in Arch's menu.lst, Ubuntu's menu.lst, and also ubuntu's fstab.  All three matched the uuid output for sda1 from ls -l...

Re: [SOLVED]Cant find my ubuntu kernel

you can also use the drive names like /dev/sda1. See if that works.

what do you mean?

here, let me post a copy of my /grub/menu.lst:

title     Ubuntu 8.10, kernel 2.6.27-11-generic
root     (hd0,0)
#uuid   d38232e9-8c7a-45ae-8db0-13b5207b404a
kernel  /boot/vmlinuz-2.6.27-11-generic root=UUID=d38232e9-8c7a-45ae-8d$
initrd    /boot/initrd.img-2.6.27-11-generic
quiet
