    My macbook pro leopard needs to be reinstalled. When I first purchased the laptop I made a backup image in .ISO and placed it on a 16GB flash drive.

    How do I boot into this drive to reinstall leopard?

    Disk 2 refuses to work no matter how many times I clean it :mad:

    Isn't OSX on disk 1? Anyway you need to make sure the device is bootable. Try using Carbon Copy Cloner.

    You can only boot off firewire devices I had thought... I know when I ISO'd my Leopard disc, I had to put it on a firewire drive.

    If your disk is bootable, simply connect it to your Mac via USB or FireWire and hold in the Alt key during boot up.

    Yea you can boot onto USB drives.

    The thing is, that I dont think you can boot iso.

    If you used disk utility, you have to use the option thats similiar to restore image or something like that. That will take a dmg/iso, and make it so that its bootable on your usb drive.

    only true with PowerPC macs, intel macs can boot from USB as well.

    you would have had to reformat the Flashdrive to HFS+ with a GUID partition table to be fully bootable.

    either way, you should be able to still mount the .iso and easily install it just as if you had the disk without having to boot at all.

    an iso file is an image, so it is not bootable itself, if first need to be burn (open the iso with disk utility for that)

    but anyway, only the dvd1 is necessary to install mac os. the additional installs on dvd2 do not need to have the physical dvd - just copy the iso to the desktop, then open it. it should mount and been accessible from the desktop exactly as if it was a physical dvd.


    By the way the macbook will actually boot from usb, as long as the usb device holds the right files to allow boot up (ie not an iso file - but a bootable filesystem)


    hope it helps...
