    Have you tried booting from the pendrive with lion on it? If you had Sierra on the MBP and then boot from the internal Recovery partition (command + r) then it will be for Sierra.

    I think you need to boot from the bootable Lion drive, erase the whole internal drive, then install Lion.

    EDIT: BTW, it would be helpful to include which model MBP you have when asking for help with problems. I don't know if your MBP will even support Lion.

    Which model MBP do you have?
    If the pen drive was made to be bootable, then restart the MBP, hold down the option key, and select the pen drive.

    The Late 2012 13" MBP does not support Lion (10.7). The oldest OS it will support is Mountain Lion (10.8).

    What was the reason for your wanting to downgrade to Lion?

    It sounds like from your first post that you already erased the OS. Your only startup option from the internal drive is the Recovery partition (command + r) now.

    If the problem is the internal drive than no software (OS install) will fix a hardware problem.

    If the internal drive has not failed;
    Have you thought of using Internet Recovery (command + option + r) which download and install the OS your MBP shipped with (10.8).
    Here is a list of startup key combinations.

    It sounds like you you do not have a bootable Mountain Lion pen drive. How did you create it?

    Maybe because people only discuss problems on MacRumors forum, but I have never seen anyone report making a successful USB boot drive using Transmac on a PC.

    Good luck on your Internet recovery. :)

    The drive should be journaled to install and run the Mac OS.

    I have never encountered not being able to erase and selecting journaled. I'm wondering if you are having an issue because your internal flash drive is core storage.

    How specifically did you erase the internal drive? Did you use Disk Utility and select the top drive model name and not the volume name (normally the default would be "Macintosh HD")?

    What specifically is the "another error"?
