Hey Nate,

You might also be able to fix that by just setting the active/boot
partition on your drive back to your linux install.  You can do this
using fdisk in linux or diskpart in windows.  Hopefully, once the
active/boot partition is set back to linux the MBR code should jump to
the right bootloader.
