    Default How To Make a OS X Lion Boot Disk

    The first question that popped into my head after it was revealed that Lion would be a download only upgrade was "what if I need a boot disk?"

    I've had too many hard drives crash, and had to reinstall too many operating systems to do without a physical boot disk. Plus I've never been one to tote around an external bootable hard drive. Thankfully creating a Lion boot disk is quite painless.

    Egg Freckles posted the following instructions earlier today.

    1. Purchase and download Lion from the Mac App Store on any Lion compatible Mac running Snow Leopard.
    2. Right click on “Mac OS X Lion” installer and choose the option to “Show Package Contents.”
    3. Inside the Contents folder that appears you will find a SharedSupport folder and inside the SharedSupport folder you will find the “InstallESD.dmg.” This is the Lion boot disc image we have all been waiting for.
    4. Copy “InstallESD.dmg” to another folder like the Desktop.
    5. Launch Disk Utility and click the burn button.
    6. Select the copied “InstallESD.dmg” as the image to burn, insert a standard sized 4.7 GB DVD, and wait for your new Lion Boot Disc to come out toasty hot.

    Now you know how to make your very own OS X Lion boot disk once Lion is available. You will be able install it on any of your Lion compatible Mac's like you did before the digital download revolution. And for the Macbook Air or Mac Mini server, which lack an optical drive, users can utilize Disk Utility's Restore function to image the Lion boot disc onto an external drive to perform a clean install.

    Unless you've got an early build of Lion, bookmark these instructions, copy them, or store them away in your photographic memory for future use when Lion is available next month.

    I haven't tried the lion beta yet. But I am going to assume that once it creates the recovery partiton you can launch it and clean install the OS.
    Anyone have any input on wether or not it works this way?

    Yay!!! I knew someone was going to figure this out... Just didn't think it would be one day. Lol

    I hope Apple doesn't change this. I've been running a Hackintosh for quite sometime now...

    Not to make this sound or come across trolling, as i can see were some will want a bootable disc, but.

    Lion as Apple state's in the features article on the webpage,
    Built into Lion
    OS X Lion includes a built-in restore partition, allowing you to repair or reinstall OS X without the need for discs.

    Browse the web with Safari

    Recovery mode now includes the Safari web browser, so you can check your email or browse the Apple Support site.

    Reinstall OS X

    OS X can be reinstalled on your Mac from recovery mode.

    Restore from a Time Machine backup

    Use recovery mode to restore your Mac from a Time Machine backup.

    For the hackintoshers...Isnt Lion 64bit only? I run a dell mini10v and would like to go to Lion but I recall someone saying on mydellmini that lion is only I wrong?

    I would really hate to have to download this over my 3G aircard as I get capped at 5GB/mo.

    FAIL for not selling discs.
