When I boot from a Lion DVD on a MacBook Pro 9,1 I always get the anti sign. The same DVDs will boot other MBPs just fine, and I can boot this machine from a Mountain Lion DVD.

Not too much info to go on... however, if you boot your MacBook Pro 9,1 with a Lion disk prior to 10.7.4 it will not boot. It will, however, boot from versions of Lion 10.7.4, 10.7.5, and of course Mountain Lion.

Well as Lion was not produced on a DVD, where did you get it or make it?

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

Ah. Is there any legitimate way for me to get a 10.7.5 installer? Or will Apple force me to do the .torrent route? I'll bet that's the issue.

Maybe a good question would be...where did you get the Lion and Mountain Lion installer you currently have?

Why not just install Mountain Lion or do internet recovery?

$20 direct from Apple - link.

Have no clue what version is downloaded.

I cannot be held responsible for the things that come out of my mouth.
In the Windows world, most everything folks don't understand is called a virus.
