[SOLVED] Ubuntu not booting after Switch to Arch's Grub2

Hi, hoping someone can help with this. I changed the grub2 on my /dev/sda to Arch's version, instead of Ubuntu's, and now I keep booting into the initramfs prompt whenever I try to use Ubuntu. The automatic OS detection won't find it when I run the mkconfig command on grub2's wiki, and I currently have the following in Custom:

enuentry "Ubuntu Linux" {
set root=(hd0,3)
linux /boot/vmlinuz-2.6.35-23-generic
initrd /boot/initrd.img-2.6.35-23-generic root=dev/sda3 ro quiet
}

Which according to my partition layout, and a double check on gparted, is correct. Do I need to flag it as boot or something else? I tried putting Ubuntu's grub2 back on with the live cd but it kept saying /dev/ was busy.

Cheers,
Ben.

I ran into the same issue. I think the easiest way to fix it is to install os-prober from AUR and re-run grub-mkconfig -o /boot/grub/grub.cfg.
