Documentation Updates

I've been trying to get Debian installed on my Lenovo C630, but after the installation completes and the computer reboots, it doesn't go any farther than GRUB, regardless of whether I follow the DtbLoader instructions (of which, I'm not confident I did right - more on that later). There are some parts of the documentation I'm a little confused by:

• Under "Installation Tips", I think it would be handy to point out that using dd is a fast effective way to get the ISO to boot from a flash drive.
• Also under "Installation Tips", it isn't clear how partitioning should be done. For me, I want to boot off an external drive (for now). I found you need a fat16 boot+esp partition; the Guided option in the installer will do this for you.
• Under "AArch64 Quirks", it isn't entirely obvious that you have to boot into the installer's UEFI shell. Not a big deal, just a little unclear.
• I don't get what I'm doing for steps 3 and 4 in the quirks section. To my understanding, this is what you would need to do if you're dual-booting Windows while installing to the internal SSD, but I can't tell entirely if that's right because I don't meddle with this sort of stuff. I was already able to boot from my external drive without following these steps, but I'm not sure if there's more to it. I say that because whether I followed those steps or not, I never succeeded in getting the laptop to do anything beyond the GRUB menu - telling it to boot Debian just sat there and did nothing. No errors either. I'm sure I'm doing something wrong, but I don't know what it is.

TL;DR: Some adjustments to this guide for booting on an external drive would help solve some of these quirks. I feel like I'm half way there but I don't know what to do when I'm not given any errors.

The document is really meant for installing Debian onto internal UFS disk rather than external drive.
