    EDIT: resolved a two day struggle right after I posted here :p. By installing 10.6 on the HD, the system no longer throws out any error messages while trying to install LION fresh from a DVD.

    I'm posting here rather than software forum in hopes that another 2006/07 15" MBP owner can share insight. Just to clarify, it is the model with the ATI X1600 video card.

    I'm helping a friend who is receiving an error message when trying to install LION on his MBP, and also receives the error if he tries to boot via USB to a known good 10.7 HD. Details:

    -MBP successfully had 10.7.1 with oem equipment.
    -he ordered an SSD and began reading about TRIM enabler. Not knowing enough about it he installed and turned it on... with the OEM platter hard drive still installed.
    -immediately after rebooting, the computer stays at the grey screen with the "prohibited" sign flashing. No luck resetting SMC or PRAM.
    -decided to perform a clean install, but now LION will not allow him to install. I advised him to find a known good copy of LION burned on a DVD, which he did at a local Apple service center. NO LUCK.
    -However he is able to install Snow Leopard evidentially.

    Did he screw something up with the Hard Drive's firmware... OR worse; did he screw up something with the MBP firmware or efi?

    I am trying here for any insight at all. The fellas at the service center were stumped, and couldn't offer any solutions short of checking it in for full service.

    EDIT: The error message he receives says "There was a problem installing Mac OS X. Try reinstalling."

    The Lion installer does not require 10.6 to be on a hard drive in order to run. The downloadable installer won't upgrade 10.5, but it's absolutely possible to install 10.7 on a blank drive. Therefore, if this was failing, then there's something else going on.

    Oh definately there was something else going on. The mbp had 10.7 from a clean install before the guy decided to enable trim on a platter hard drive. So we knew his burned DVD of lion dmg was not corrupted. I think he is just very relieved he didn't screw up the logic board firmware.

    I guess lesson learned is don't go messing with TRIM Enabler if you are not using an SSD. Not sure what he expected anyway.
