dualboot ubuntu-arch

after i've installed yesterday arch linux i can't login into my ubuntu that i've mounted in other partition, because when i choose to run ubuntu from grub it gives me "error 15: file not found", here there's my menu.lst, anybody can tell me how can i do to make ubuntu work?

You have a typo. You're missing a / in from of dev where you specify root.

Change root=dev/sda3 to root=/dev/sda3

Re: dualboot ubuntu-arch

You also have the same root specified for both Arch and Ubuntu.

For arch you have root (hd0,3) which does correspond to kernel paramater root=/dev/sda4.

For ubuntu you have root (hd0,3) again but you have root=/dev/sda3. If kernel parameter root=/dev/sda3 is correct for ubuntu then you have to change to root (hd0,2).

Re: dualboot ubuntu-arch

Can you please just install GAG to MBR, and always install grub to _root_ ( i.e. boot) partition. Then, you'll have non of these problems in the future with mixing linuxes / BSDs / WinXP...
