I don't know what's going on, but I would try to manually boot the Debian kernel from GRUB2 console. As you're using GRUB2 from Ubuntu, you could try these steps: https://help.ubuntu.com/community/Grub2#Boot_a_Specific_Kernel_Manually > I check the UUID (via GRUB2 -> ls) it is identical as the one specified > in the GRUB parameters. Maybe what can't find is the root disk/partition (hdx,x). Besides, it can be an error coming from GRUB2 itself, that's why I still suggest that you try to boot your Debian system from SuperGrub2Disk which is distribution-unaware. As a side note, when using a multi-boot configuration I prefer to install the bootloader of every operating system inside its own partition, whether possible (windows does not allow this, I guess, it puts its NT loader on the MBR we like it or not). But on linux and bsd systems you can install both, Ubuntu and Debian, and each of them with their own GRUB2.
