boot-installer accessability: edit in installation-guide

[Holger Wansing <hwansing@mailbox.org>]

Hi Samuel,

I would like to recommend some proofreading for your latest installation-guide
commit.

I have added some formatting tags (like <keycap>&enterkey;</keycap>) for the 
keystrokes and some other minor things (like avoiding the three-times use of
"just" in one sentence).

A diff is attached.


I can also push it, if you want.


Regards + Merry Christmas to you and your family!


Holger
