The problem ist that setup-storage creates a new partition table.
If you write a hook to restore the old signature it will work.

save signature:
dd if=${WINDOWS_BOOT_DEVICE} of=${BACKUP_PATH}/${WINDOWS_BOOT_DEVICE_SIGNATURE_NAME} ibs=1 skip=440 count=4

restore signature:
dd if=${BACKUP_PATH}/${WINDOWS_BOOT_DEVICE_SIGNATURE_NAME} of=${WINDOWS_BOOT_DEVICE} obs=1 seek=440 count=4
