I have an issue with Ubuntu since Quantal, Raring is concerned too. After the Install I can't boot to the system. I have no Windows on my PC, I just have Ubuntu on both partitions : One as main system and the second for testing. Precise was the version I could install and be able to boot after. Grub says : Reboot and insert a proper boot device ... I tried all I could find but still have the same issue. The only Option I know will work now is installing Precise, but I DON'T WANT THAT ( just to be clear ).
I tried BootRepair without any success. Here is the logfile created by BootRepair after some attempt.
After Install, trying nothing, Bootrepair produced this log : http://paste.ubuntu.com/5604883/
After Reinstalling, separating the boot partition :http://paste.ubuntu.com/5604927/
After letting Bootrepair Install grub-legacy instead of Grub2 which reported one error: http://paste.ubuntu.com/5605140/
I can't use my computer at all without the Live USB.
Worth mentioning too, my Computer is not UEFI compatible, so no uefi here.
Update : Today I tried grub-emu from the live USB, I did as folow :
sudo mount /dev/sda1 /mnt sudo mount --bind /dev /mnt/dev grub-emu -d /mnt/boot/grub
and I can see that grub-emu sees my grub Infos. But when booting from the HDD I still get the same issue.
