ISO image???

[cracked]

i think i know what to do, but i want to get it straight. if i sound like an idiot, then please tell me the right info.

an iso image that is downloaded, when burned to a cd, makes a cd that is exactly like a cd you would order or buy from the same people, am i right? i think this is right but im not sure.

Correct. But if its a bootable CD like Windows XP/2000 then you have to set the options to bootable in the burner software.

"A Linux iso is a file containing a cdrom disk image of a Linux distribution. This cdrom disk image is an exact copy of a Linux distribution on a cdrom. Think of it as the equivalent of a screen capture, but instead of capturing the information on a screen, this image captures all of the information on a particular Linux distribution's cdrom. When burned as a disk image, the .iso file is turned into a duplicate cd of the original cd. If burned as a file, instead of a disk image, the cd becomes a copy of the downloaded .iso file, and not a bootable cd with accessible files and directories."

That's not quite true, when creating an iso, the bootable part is apart of it. Then you don't need to mess with that or you will make it becaome unbootable unless you use the boot image from the cd-rom, Which eitherway adding another isn't the best idea.

Yeah, the ISO might be understood as a complete bit by bit copy of the original CD, but certain copy protection schemes will result in blowing the ISO full of errors. Creating an ISO means copying the source data, but if the data is arranged so as to appear to be corrupted data, the ISO creation program will try to correct what looks like corrupt data, which alters the deliberate data structure into something else and thereby ends all usefulness. Something like that.
[EDIT] There is still more but that gets the idea across. [/EDIT]
