which gives an error: mkisofs: No match

First I thought the directory name [BOOT] was weird so I changed this to
BOOT. Running mkisofs -r -J -b BOOT/Bootable_HardDisk.img -hard-disk-boot
-o raid.iso /data2/tmp creates an iso, but when I burn this to a cd it
doesn't boot.

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?



Strange thing also is the fact that the original iso has the size of
~17MB, but the created iso by me is ~10MB. So it seems I'm missing some
files.

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.
