More information about my initial problem: I was able to take a picture of part
of my screen using my phone, and Google is telling me that GRUB is loading into
rescue mode with an error that says something about "unknown filesystem."
Sorry, I can't get much more detailed than that, because the text conversion
wasn't exactly perfect. My /boot/grub/grub.cfg is inserting the btrfs module,
so I am at a total loss. Maybe I need to take out all the if syntax and only
search for the UUID. i realize this is a somewhat nonstandard install, as I am
trying to get a bootable USB key with a BTRFS filesystem using the Arch install
media that I have written to another USB Key in a computer that is running
Windows XP, but I do hope this is possible. Note that since this is a USB boot,
I'm not at all concerned about booting the Windows XP OS on the hard disk,
because I can boot it as long as I don't choose USB boot or remove the USB key
from the computer. I hope I have provided enough information.
