Thanks for your work on documenting grub which I plan to use with my 
installation of GNU/Linux. I have a comment on the GRUB documentation 
posted online for version 1.99.

3.4 BIOS Installation, MBR section says: "there are two ways to install 
GRUB: it can be
embedded in the area between the MBR and the first partition (...), or 
the core image can be installed in a
file system and a list of the blocks that make it up can be stored in the
first sector of that partition."

However, when I look at 3.1 Installing GRUB using grub-install, there is 
no explanation about where the 'core image' is installed or how its 
placement is controlled.

My observation comes from trying to find out if I can boot GRUB if I 
'install' it in a /boot logical partition on an MBR harddrive. I will 
just try it not knowing the particulars and see what happens. I can 
always start over using Clonezilla, which seems to have worked for me 
once. It seems that OEM Windows 7 installed in an MBR format will not 
adapt to the GPT format and I am not paying for MS installation CDs. So 
no GPT for me. Happy Holidays and any religious salutations suitable to 
your self-identity.

The best suitable placement is automatically determined. Block-lists are 
only a fallback if mbr gap is unavailable and should be avoided due to 
reliability and security problems.

As long as you install to MBR and not to partition it's fine.

You need to reinstall bootloader after cloning in any case

Microsoft misinforms you that you need EFI to boot on GPT.
