Create Dmg From Windows Mac App Store

I backed up the Lion dmg file when I purchased it via the Mac App Store.

My friend created this Recovery USB and made a DMG file using Disk Utility and sent it to me over internet.

Then using TransMac I burned DMG on my USB stick and was able to recover my macbook from failure.

DiskPart successfully converted the selected disk to GPT format.

I got a prohibition sign when attempting to boot from a USB created through transmac with the GPT.

However, the other option is to use a Virtualbox VM to run OS X temporarily (scroll down for that info).

If youre burning it to a DVD, insert your DVD, select the disk image in the sidebar, and hit the Burn button.

Go to the Partition tab and select 1 Partition from the dropdown menu.

Hit the Apply button when youre done to format your drive (note: it will erase everything on the drive).

Hit the Apply button and it will create your bootable USB drive.
