Re: Boot problem : Operating System not found.
It would've been helpful not to have snipped the drive partition info section! :) You have a gpt-labelled disk but sda1 isn't OK. As File system, it should have BIOS Boot partition. Boot sector type and Boot sector info cannot be right but I don't know what they should be. The two looks at sector seem *very* wrong. OK, hereafter I added the drive info produced by boot_info_script.sh. I'll also try the SuperGrub2Disk ASAP. Bye.

I suppose this is an interesting info. What happened ? How to correct this ? 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.

Debian is installed) :
