This happened because of my lack of knowledge in GRUB I managed to fix this after some research, apparently i didn't know that GRUB use a different kind of numbering of partitions (e.g 1 in mbr means 0 in GRUB)
and after all I did install GRUB into (hd0) as default, and it works fine. Thanks for the great Ubuntu :) * I can't attach the /var/log/syslog and /var/log/partman to this bug since I ahave done a fresh Install again.. -- Installer crashed https://launchpad.net/bugs/73335 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
