I'chiliad going to walk through the process of making a bootable Mac OS X 10.7 Lion installation bulldoze out of any USB flash bulldoze cardinal. This is similar to the process of making a bootable Lion installer DVD, but I prefer a USB flash drive because it'due south faster, smaller, and I have a MacBook Air then an installation DVD isn't too useful for me.
