[arch-general] Installation_Guide - fix concerning bootloader config reference

[David C. Rankin]

Guys,

  One place the Installation_Guide could be improved is regarding the bootloader
install and config. Currently the "Configure system" section has a
circular-reference back to "Install a bootloader" section. It reads:

-------------------------------------------------
 Install a bootloader
GRUB

    For BIOS:

# pacstrap /mnt grub-bios

<snip>

Configure system
...

Configure the bootloader: refer back to the appropriate article from the
bootloader installation section.
-------------------------------------------------

  Above, the reference back 'to the appropriate article from the bootloader
installation section' sends the reader back to an area with NO additional
information. It would be far better to simply refer the reader to:

https://wiki.archlinux.org/index.php/Beginners%27_Guide#Configure_the_bootloader

or just include the bootloader config steps from Beginners_Guide. Bolding
"Configure the bootloader:" would also help.

  That will emphasize the fact that grub2 is not configured at this point and
the user needs to complete grub-install and grub-mkconfig before rebooting.
Especially for user seeing grub2 for the first time with an install from the new
2012 media.

  That's just a suggestion for readability. Thanks.
