$ grub2-install /dev/sda
Installing for i386-pc platform.
grub2-install: warning: File system `ext2' doesn't support embedding.
grub2-install: warning: Embedding is not possible. GRUB can only be installed 
in this setup by using blocklists. However, blocklists are UNRELIABLE and their 
use is discouraged..
grub2-install: error: will not proceed with blocklists.

/dev/sda does not have a partition table and is used entirely as an ext* filesystem which does not have a dedicated area for GRUB's core image (unlike btrfs). You could force installation of the core image in a regular file using blocklists with --force but this is considered unreliable. IMO the boot drive should have a partition table.
