How do I Make A Bootable OSX Image

I would like to learn how to make a bootable dvd and a bootable hard drive(you can never be to careful). Can I use my internal hard drive or does it have to be external?

@Voyn1xUsing disk utility you can restore it to another drive or partition. It won't be bootable on it's own as the bootloader is held in the mbr. After restoring it, you can download and install the chameleon bootloader to the drive. FYI, it's also possible to boot a drive using the install dvd's bootloader. Just start from the dvd and…

Hey Voyn1x(or anyone else)
where can i find the mach_kernel file so that i can make a copy of it before i upgrade to 10.5.6. i double click on the osx partition and i get 4 folders(applications,users, system and library). where do i go from there?
THANX

@zuz242the kernel file resides in the root directory of the osx partition, but is hidden. best way to back this up (and the kexts) is to use osx86tool

is this osx86 tool part of osx86 or is it a program i would have to download? if it comes with osx86 where can i find it? if not where can i download it from? what do i do when i get open this tool?
THANX IN ADVANCE

I got it working by installing the chameleon bootloader just like you said Voyn1x

EVERYTHING IS A OK

do you want to boot it from a disc or an external hdd?
