I just checked for my working USB image and the
boot/grub/grub.cfg contains that line

bzImage --root=31393730-3031-3031-3139-343934363833 
--system=/gnu/store/2j79kbvsxqq7lmzp3isnran1dpcp2z5j-system 
--load=/gnu/store/2j79kbvsxqq7lmzp3isnran1dpcp2z5j-system/boot quiet

but I cannot find that partition either.  It seems to be created by
grub-mkrescue from make-iso9660-image, but I am not sure.

@Calvin: The manual contains this line in section _Building the
Installation Image_ (with Mark’s --system=i686-linux added):

guix system disk-image --file-system-type=iso9660 --system=i686-linux \
       gnu/system/install.scm

If you omit --file-system-type=iso9660, a USB image will still work
and I believe no --root=31393730-3031-3031-3139-343934363833 will be
inserted in GRUB.
