Add note about bootme flag:
        The bootme flag is used to indicate which partiotion should be booted
        by UEFI boot code.

Fix a typo, and make a couple of minor wording improvements.
I resisted the (very weak) impulse to Americanise some spellings ...

Use Fx/Nx.

clarify that alignment is the number of bytes to align to.

Explain what suffixes are accepted when specifying a size.
Spelling

add information about how to boot from gpt.  mostly taken from the wiki.

if a new map entry doesn't fit, be more verbose about the sizes.
