How to install an OS from a .dmg without burning it?
I have a .dmg image of OSX Server I want to install, but I dont have a dual layer DVD-R to burn it to
Theres a few suggestions here
which seem to say that if you put the .dmg on another partition or extract it there, you can boot from that partition as if its a CD
How do I do that?
Ive tried just copying the image to the partition, and also mounting it in OSX and then copying it to the partition, but when I boot and hold the option key, the only partition it lets me boot from is the one with OSX on it, not the one with the .dmg
Is this possible? What am I doing wrong?
