    Is it possible to install Snow Leopard from a disc image on an external drive?

    Just put the DVD into your drive and boot off that.

    Thats the problem, my internal DVD drive is failing and I don't have access to an external. But I have access to another Mac and an external drive. Before I buy snow leopard, I want to make sure I have a way to install the software.

    I asked pretty much the same question in another thread. Unfortunately no help thus far. I remember reading about people doing it from flash drives, so I'd assume an external hard drive is easily doable.

    Well if it helps any, I mounted the leaked 10.6 onto an external drive then installed to my MBP.
    Considering its the same build, I don't see why it wouldn't work. :)

    PS Just waiting for my 10.6 disc to get here...

    Of course it's possible, you format the hdd in Mac OS X extended, then create an image of the SL DVD, restore it to the HDD and boot on it. Then you'll be able to install SL from the hdd. I did it. Google is your Friend.:)

    1/ Put the DVD in the other Mac

    2/ Connect both macs via FireWire

    3/ Shut down your Mac (the one you're installing onto)

    4/ Reboot the other Mac, holding down "T" as you do, until you see a yellow firewire screensaver

    5/ Startup your Mac, holding down [OPTION] (also labelled 'alt') key, until you see the other Macs DVD icon listed - click the arrow in the circle directly underneath it, and you can start the install
