According to your logs, you tried to install grub to /dev/sda and this can not be done because it is partitioned with GPT and you are booting in bios mode, but have no bios_grub partition. If you wish to install grub to /dev/sdd, then choose the "something else" option, configure your partitions, and select /dev/sdd as the location to install grub to.
