You should be able to use the dd of the partition as an initrd,
if you have enough free memory (and the filesystem driver in the kernel,
not a module). Or use an initramfs:
ln -s sbin/init /init
find / -xdev ! -wholename /rd -print0 | cpio -o0Hnewc | gzip -9 > /rd

In both those cases, you'll have to have a correct /etc/fstab, or fix
the boot process to use a correct one.

Or an initrd that boots the hdd image via nbd, nfs, etc.
