[SOLVED] Grub finds "unknown linux distribution" on my usr partition

I installed arch linux today and for some reason grub finds an unknown linux distribution on my usr partition. My system is still old-school (Bios and MBR partitioning). As recommended in the wiki, I installed to disk. Note that it works, i.e. I can boot to arch, windows and ubuntu. I just wonder why it finds a linux distribution on my usr partition.

[dean@PsyGeek src]$ LC_ALL=C sudo grub-mkconfig -o /boot/grub/grub.cfg
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img
  No volume groups found
Found Windows 7 (loader) on /dev/sda1
Found Ubuntu 12.04.3 LTS (12.04) on /dev/sda10
Found unknown Linux distribution on /dev/sda7
done
[dean@PsyGeek src]$ LC_ALL=C df -h

Re: [SOLVED] Grub finds "unknown linux distribution" on my usr partition

Did you format that partition when you installed Arch?

Please post grub.cfg.

Well try booting into that unknown distribution first, and post the results.

Re: [SOLVED] Grub finds "unknown linux distribution" on my usr partition

The unknown linux distribution is not in my grub menu anymore. I'm not sure how that happened.
I runned grub-mkconfig again and although it still says it found an unknown linux distribution on /dev/sda7, it doesn't add it to the menu (and/or grub.cfg) anymore. I checked grub-mkconfig manual and there is no debug or verbose flag so I guess I have no way of finding out what happens so I marked the topic as solved.

I formatted all partitions btw. I didn't post my grub.cfg since there is no entry about my usr partition anymore.
