If this is depending on the name "[BOOT]", there are
two ways to deal with special characters in file names,
if you need to specify them on the command line:

a) use escape sequences:
	-b \[BOOT\]/Bootable_HardDisk.img

b) use quoting:
	-b "[BOOT]/Bootable_HardDisk.img"

Also read "man mkisofs" about the boot-related
options, especially -b, where

	If  the  boot image is not an image of a floppy, you need to add
	one of the options: -hard-disk-boot or  -no-emul-boot.   If  the
	system should not boot off the emulated disk, use -no-boot.

is mentioned. Maybe consider using -G instead of -b?

You can mount the ISO you've generated and look inside
to find out which files may be missing, or if there are
differences in file sizes.
