Once I had the Mountain Lion up and running on my HP Envy 15t-J001 machine, the next step was to setup a boot loader, so that I can boot it without the USB every time.
I was using Clover, and it has pretty good support for the EFI Motherboards. However, my only concern was I didn’t wanted to loose the HP Recovery partition by accident or incorrect configuration. Plus I wanted to keep the current boot loader, but still somehow boot to OS-X without using USB…
