the deal is im trying to get OSX running on my pc, ive come pretty close so far and fixed a few issues already such as getting OSX to recognize my sata drive which was said to not be possible with my chipset. my problem now is that i cant use a regular boot dvd to install it any more, i only have the ISO image, how can i boot this off a external hdd? if i just plug the external in and try booting (with the correct, i think, bios settings) it tells me NTLDR is missing. what i have been trying to do to fix that is use a program called testdisk (http://www.cgsecurity.org/wiki/TestDisk) which turns external usb drives into dos bootable disks. but i want to replace the dos command.com with the OSX one, theoreticaly turning it into a OSX bootable drive which is what i want. but i dont know how to get that file out of the ISO. am i on the right track? or trying to achomplish something impossibe? any help or insight? any body have a better method of using the external to boot? or does anybody know how i can get the command.com file i need out of the ISO? if i just mount the image and view the files theres only a few files, none that i need, because i think the other files are invisible to windows?
