[Solved] New Arch install boot problems. Error 15: File not found

hello all,
Another Arch noob here....:rolleyes:
Would appreciate some help with what appears to be a Grub installation problem:

I have used the 'Install from Existing Linux' part of the wiki, to install 64bit Arch on my second hard drive.
1st hard drive has Ubuntu 9.04 on it. I want the Arch disk to be able to boot on it's own so that I can do away with the Ubuntu later.
I formatted the Arch drive partitions to ext4: (my first mistake?)

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0001ba55

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1       25496   204796588+  83  Linux
/dev/sdb2           25497       60799   283571347+  83  Linux
/dev/sdb3           60800       60801       16065   82  Linux swap / Solaris

In /boot of the second drive I can see:

drwxr-xr-x 2 root root    4096 2010-07-17 14:46 grub
-rw-r--r-- 1 root root 8330488 2010-07-17 14:25 kernel26-fallback.img

-rw-r--r-- 1 root root 2107872 2010-07-06 05:46 vmlinuz26

And in /boot/grub I see

-rw-r--r-- 1 root root    197 2010-07-17 14:28 default
-rw-r--r-- 1 root root     45 2010-07-17 14:27 device.map

-rw-r--r-- 1 root root  12872 2010-07-17 14:28 xfs_stage1_5

In /boot/grub/menu.lst I have:

# general configuration:
timeout   5
default   0
color light-blue/black light-cyan/blue

# (0) Arch Linux
title  Arch Linux  [/boot/vmlinuz26]
root   (hd1,0)
kernel /boot/vmlinuz26 root=/dev/sda2 ro
initrd /boot/kernel26.img

When I boot I get:

Filesystem type is ext2fs, partition type 0x83
kernel /boot/vmlinuz26 root /dev/sda2 ro
Error 15: File not found
Press any key to continue.....

I have tried using root /dev/sda1 in menu.lst as well and neither works.
I am wondering if my boot partition has to be ext2? Or do I need to use Grub2?
All comments appreciated

It doesn't have to be ext2 (although) a safe choice. I really don't like grub2 its been incredibly slow for me (at least from the debian system that installed it) to the same point I've see it run just fine on a netbook so there is something else going on.

root   (hd1,0)

you sure thats the right HD?

Wow that was a fast reply thanks
I want to use my BIOS boot menu (Alt F11) to boot Arch.
HD(0) (/dev/sda when on Ubuntu)has a bunch of Ubuntu partitions on it.
HD(1) (dev/sdb when on Ubuntu) has arch installed.
So I assume that from my BIOS's point of view, Arch is on the second disk in the system, which is HD1, right?

EDIT: When I set it to HD0 it boots Ubuntu

I belive thats correct, although I'd have to take another look at the [wiki]grub[/wiki] wiki. have you tried vareattions such as (hd1,1) (hd1,2) to see if one of those is correct

/dev/sdb2   ==    (hd1,1)

so I assume that would mean that the first one would be (hd1.0)
still worth a shot tho

edit: n/m fixed it
sda3 =! sda2
not really helpful now

Re: [Solved] New Arch install boot problems. Error 15: File not found

Got it.

# (0) Arch Linux
title  Arch Linux  [/boot/vmlinuz26]
root   (hd0,0)
kernel /boot/vmlinuz26 root=/dev/sdb1 ro
initrd /boot/kernel26.img

This works. /dev/sdb1 seems to be hd(0,0), but I don't really understand it. Maybe hd0 is relative to Grub. I'll go and read Grub wiki again.
I am learning even as I type this
Thanks for the help

Edit: what I've learned:
hd0,0 is the first partition relative to where the grub that boots is installed.
/dev/sdb1 is the same partition, which as it happens in this case, is the second HDD on the system.
Now I can boot either and still be free to change one distro without killing the other by means of BIOS boot menu.:lol:
