nixos manual: recommend use of dd for writing the image

Browse Source 
Unetbootin works by altering the image and placing a boot loader on it.
For this reason, it cannot work with UEFI and the installation guides
for other distributions (incl. Debian and Fedora) recommend against
using it.

Since dd writes the image verbatim to the drive, and not just the files,
it is not necessary to change the label after using it for UEFI
installations.

vcunat: tiny changes to the PR. Close #14139.

a USB stick. For non-UEFI installations,

will work. For UEFI installations, you should mount the ISO, copy its contents
verbatim to your drive, then either:
a USB stick. You can use the <command>dd</command> utility to write the image:
<command>dd if=<replaceable>path-to-image</replaceable>
of=<replaceable>/dev/sdb</replaceable></command>. Be careful about specifying the
correct drive; you can use the <command>lsblk</command> command to get a list of
block devices.</para>
<para>The <command>dd</command> utility will write the image verbatim to the drive,
making it the recommended option for both UEFI and non-UEFI installations. For
non-UEFI installations, you can alternatively use
