grub2 can't find kernel with dual boot

[Foxy]

I have Ubuntu 9.04 Jaunty as my main OS, where I have upgraded GRUB to GRUB2. I have also installed Ubuntu 9.10 Karmic on separate partitions. I am trying to boot Kramic, I have a message that I need to load kernel first. It looks like GRUB2 cannot find kernel. Probably the problem is that I have /boot on a separate partition.

This is my config:

/boot/grub/grub.cfg (Karmic entry):

menuentry "Ubuntu karmic (development branch), kernel 2.6.31-2-generic (on /dev/sda6)" {
    set root=(hd0,7)
    linux /boot/vmlinuz-2.6.31-2-generic root=UUID=6ad1f928-50b9-4aea-9495-95df46d08d58 ro quiet splash
    initrd /boot/initrd.img-2.6.31-2-generic
}
