I don't think the partition is damaged. You just have to reinstall grub 2 (because you changed the partition order). Start your pc from ubuntu live cd. Then install grub customizer on this temporary system (some procedure as you did on your installed system). Choose your ubuntu partition. Then run File -> install to mbr. Restart. Then the boot menu should appear.

Can you help with this problem?
