So now:

grub2-install --no-floppy /dev/sdg
/sbin/grub2-setup: warn: Your embedding area is unusually small. 
core.img won't fit in it..
/sbin/grub2-setup: warn: Embedding is not possible.  GRUB can only be 
installed in this setup by using blocklists.  However, blocklists are 
UNRELIABLE and their use is discouraged..
/sbin/grub2-setup: error: will not proceed with blocklists.

What do I do now! Embedding area???
