Hacking OS X Boot CD's
In response to my lamentations about blowing away a perfectly good partition table in my last post, jschimpf mentioned a link where I could have fixed it if only I had consulted Google and poked around a bit more.
The solution was so mind bogglingly cool that I had to write a bit more about it. Here is the link:
Basically, you need to use the Disk Utility (available when you boot from your OS X install disc) to make a new image file of the restore disk. Then, now get this, you can MOUNT THIS DISC AND MAKE CHANGES. Then burn it to DVD again.
How cool is that?
I suppose I can do that under Windows, but I’ve never heard of a way to modify an ISO image that I mount so I couldn’t begin to enumerate the steps involved. Under Windows, volumes that I mount from an ISO are generally read-only.
Thanks jschimpf

I'm flattered that you think my humble solution is mind-bogglingly cool :) I felt that I had to clear up a point though: When you're creating the image file on a Mac, you can pick from a few different formats like "compressed" and "read/write". All of the formats are read-only with the one obvious exception.
I'm pretty sure apps like MagicISO (magiciso dot com) can edit ISOs on Windows machines too, it's just a little more involved.. Another reason to go buy a Mac! :P
