Sorry, but another Error 15 boot problem...

I've scoured the forums and google about Error 15 problems and I can't find anything to solve my issue. 

   Device Boot      Start         End      Blocks   Id  System

/dev/sda10          11540       24321   102671383+  83  Linux

sda1,2,3 are windows
sda4 is an extended partition with:
    sda5,6 ubuntu swap, root
    sda7,8,9,10 arch /boot, root, swap, /home (I realise after the fact that the second swap is redundant)

When I installed arch, I accidentally hosed my ubuntu root partition, so I finished my arch install, then reinstalled ubuntu root, which built the following grub menu.lst for arch

title        Arch Linux [/boot/vmlinuz26] (on /dev/sda7)
root        (hd0,7)
kernel         /boot/vmlinuz26 root=/dev/sda8 ro
initrd         /boot/kernel26.img
savedefault
boot

Are there any overt issues that I am not seeing?  I've been working on this for a bit and just can't figure it out.  Thanks for any help!

I'd say reformat the mbr with grub with Arch's install cd, configure the menu.lst within arch to include your windows and ubuntu partitions, then you all set.

Re: Sorry, but another Error 15 boot problem...

If you put Ubu's grub in mbr you can use that to boot Win and Arch too, if you put Arch grub in /root(hda8).  You seem to have a boot partition in sda7 which is unnecessary--and would work if it were a primary partition which you probably don't want. With Ubu grub in mbr and Arch grub in sda8(hd0,7)(/root) you can add Arch entry to Ubu's /boot/grub/menu.lst using configfile method:Title Arch
                                                                                                configfile  (hd0,7)/boot/grub/menu.lst
The configfile must include vmlinuz and initrd(which the Arch one does).  Then when you reboot you would see Arch entry in grub menu. The Ubuntu forums give several tutorials for making those menu.lst entries, including the chainloading method.  (The configfile.. is a 2nd line under the Title line)
The reverse with Arch grub in mbr and Ubu's in /root would also work.
And yes the swap closest to the center of the hd would be best and faster supposedly.  Swap on a 2nd hd is another matter.
Good luck and have fun with Arch:)

Re: Sorry, but another Error 15 boot problem...

Your ubuntu-generated boot for arch is wrong! (but not ny much!)
Remember that sda8 will be your /boot-directory, but at the time of loading it is only 'root' (as per "root (hd0,7))
So - the correct should be:

title archlinux
    root (hd0,7)
    kernel /vmlinuz26 ro root=/dev/sda9
    initrd /kernel26.img

My personal preferences (and thank you for asking) - I just lump any distro into _one_ partition - unless you are playing at the edge of your hardware, there's no point in splitting it all up (the one exception of course - you need a seperate /boot-partition if you want to use ext4 on the rest - which is a pain in the posterior!)
I have one common boot-partition where all I do is to chainload - it doesn't even get mounted anywhere (unless to edit it - ie a new distro) and one common swap-partition.
