I think there shouldn't be problem with reading sectors of image because ntrld+grub4dos can load quite large files (like linux kernel and initrd) from the drive without any corruption.
But I'm very confused why loading HD image via memdisk don't work. Image that I'm loading use standard geometry and mbr/dbr placement and memdisk should provide own int 13h services for it but doesn't work. It's very time consuming make this tries when you must encapsulate more images together upload and reflash it...
