You can also do bootable USB drive images with GRUB (not GRUB2, unfortunately)
with something like this added to standard ext2 image for drive FS:

============================
HDDIMG = "${DEPLOY_DIR_IMAGE}/${IMAGE_LINK_NAME}.img"
IMAGE_POSTPROCESS_COMMAND = " \
        dd if=/dev/zero of=${HDDIMG} bs=512 count=63; \
        dd if="${DEPLOY_DIR_IMAGE}/${IMAGE_LINK_NAME}.ext2" of=${HDDIMG} bs=512 seek=63; \
        head -c 8388608 /dev/zero >> ${HDDIMG}; \
        cat ${WORKDIR}/sfdisk.one_partition | /sbin/sfdisk ${HDDIMG}; \
        echo -e "device (hd0) ${HDDIMG} \n root (hd0,0) \n setup (hd0)" | qemu-i386 ${IMAGE_ROOTFS}/usr/sbin/grub --device-map=/dev/null --batch ; \
        rm "${DEPLOY_DIR_IMAGE}/${IMAGE_LINK_NAME}.ext2" "${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.ext2"; \
        "
============================

where "sfdisk.one_partition" is

==========================
# partition table of test
unit: sectors

    test1 : start=       63, size=         , Id=83
    test2 : start=        0, size=        0, Id= 0
    test3 : start=        0, size=        0, Id= 0
    test4 : start=        0, size=        0, Id= 0
==========================

A bit hacky-whacky may be, but works good here for USB installer images.
