Tips and tricks: (not I do not have a working Lion install yet, but this is how I speed up the process of figuring out what went wrong if I was to do my install)
-Follow the instructions from the xMove tutorial on the main tonymacx86 page, up through the part where you partition your disk(s).
-Make a 3rd partition, call it Lion Tester (I made mine 15 GB).
-Continue with running xMove, and instead, install fresh onto Lion Tester.
-Try different things with MultiBeast
-When you find a working combination (idk about you guys, but when I did my 10.6 install, I had one hell of a time getting my stuff to work) then install Lion from the Installer partition, which you left on the disk!!! and run the same MultiBeast settings you did in Lion Tester
-Enjoy your tested install
My rig: 60 GB OCZ SSD with SL and Installer partition, and my 500 GB WD Caviar Black with a clone partition, a data partition, and a Lion Test partition. Notes on all my hardware in the sig below.
