I am still seeing only Debian and Windows 7 in GRUB. Try running update-grub on the Ubuntu partition. If these are on partitions on a single disk then make sure that you don't writ this Ubuntu results to the MBR. You just need to regenerate grub.cfg for Ubuntu. Then do the same for Debian but tell grub to write to the MBR. If these are on separate disks then have the ubuntu update write to the boot partition on the disk that it is installed on. Then have debian write to the MBR. I expect that the MBR is on a Windows 7 disk that is mounted as your start up disk as Win7 does not play well elsewise. If possible you have these on separate disks then change the boot sequrence in you system bios to have your Debian disk as the first boot disk. I have such a setup. Debian, Ubuntu, Linux Mint, Windows 7 pro in that order, Each on its own disk. frosty -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

[SOLVED] Debian's grub doesn't detect Ubuntu (was: Re: Debian's grub doesn't detect Ubuntu)
Hi, This issue is now solved. I wondered why Debian's GRUB doesn't detect Ubuntu, but Ubuntu's GRUB detects Debian at #ubuntu-fi-offtopic on freenode and I got answer that Debian doesn't have os-prober. I noticed that that package is available on Debian repositories, installed it and ran os-prober and update-grub as root and then GRUB found Ubuntu. signature.asc Description: OpenPGP digital signature

You could, most likely, enter it by hand into the grub configuration; it should then be available on your next reboot.
