    I have Lion installed on my 2011 Macbook Pro and was trying to boot the computer from a 10.5 disk and get some kernel errors on the screen when doing so. This was booting while holding C at boot and also via the installer and reboot when in Lion. Does anyone know if this is possible? I'm trying to boot it up via the 10.5 disk so I can install 10.5 on a USB flash drive.

    Thanks.

    I don't think 2011 MBP supports booting from 10.5 installation media.

    No it doesn't support 10.5, you have to use 10.6 (the grey disk it came with) or 10.7 with it. If you need to make a 10.5 boot disk you are going to need to get an older Mac that supports 10.5.
