[arch-general] BTRFS USB key fails to boot

[Kyle]

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.
