How Can I Create Bootable USB for Mac OS X Mountain Lion?
My dad's old iMac 2007 was broken and replaced with a new hard drive. This Mac comes with Mac OS X Mountain Lion when it was shipped. How can I create a bootable Mountain Lion USB on a Windows PC so ...
I have encountered similar problems before, and I want to install the system on an old Mac. To create a Mountain Lion boot disk on Windows, UltraMDG is a good choice. You just need to download this tool, plug in the Mountain Lion installation package and 8GB USB drive you have prepared, and then use UltraMDG to write the boot disk.
I followed this guide and succeeded!

Compared with other complicated methods, this tool saves a lot of trouble, I recommend you to try it!
If you are going to create Bootable USB for Mac OS X Mountain Lion, the "dd" command or createinstallmedia in Terminal is your friend here. If you're not entering the commands correctly (like having typos or wrong paths), it's just not gonna work. Spend some time getting comfy with that Terminal—trust me, it's a lifesaver! After you've done all this and made your bootable USB, always double-check it works before you actually need it. Boot your Mac from the USB and see if it takes you to the install screen. Better to discover issues now rather than in a crisis!
- This method sounds very practical, but to be honest, I am still a little unfamiliar with using Terminal, especially when using the dd command or createinstallmedia, I am always worried that I will accidentally make the wrong path or spell the wrong command. I wonder if you have encountered similar problems? In addition, after making this bootable USB drive, how can I check whether it can really be used? I feel that it will save a lot of trouble if I can find the problem in advance.
