    Hey all, my cd rom drive is dead on my first gen MacBook and after a hideous freebsd install I'm at a point where I need to either bless my osx partition so I can see it during boot or completely reinstall it via USB. The problem is I wiped the contents of my USB drive (osx snow) for the freebsd install :/

    Now I have a windows 7 box around, therefore can I place the snow leopard DMG on the USB in windows and format it so that it will be bootable on my Mac? What other ways can I go about this?

    Your time and effort is highly appreciated!

    I believe the USB stick will need to be formatted to the OS X file system.

    Also you have to copy the contents of the .dmg file across to the memory stick and I dont know if you can extract .dmg files on a Windows machine.

    On a Mac you mount the .dmg file and then copy the contents across using the Disk Utility so I think you're going to need a working Mac to do this.

    Yup, generally speaking you need a Mac to prep and create a bootable USB thumb drive. At least that's all that I have read when dealing with this, as most hackintosh users need a bootable OSX thumb drive.

    Thanks for the feedback guys. I was under the impression that a win app such as macdisk would format the drive into hfs+ And ex the file?

    Well I also have a cousin with a hackintosh. Will I be able to format the USB into hsf+, guid it and properly mount the img there with disk util? Not too familiar with the hackintosh. One more, thank you.
