installation say complete but at the same time fatal error while creating boot loader.
I tried to reinstall Ubuntu after I was not allowed to update (it said there is not enough space which is not true so I though the installation was corrupted and reinstallation was needed)

Your disk is partitioned with GPT but you are in a bios booting computer. This requires you to create a 1 mb bios_grub partition.
