    Hello
    I was messing around with mountain lion and then i decided to downgrade back to lion i googled it and i found a way using the recovery mode,i erased macintosh hd and i clicked reinstall mac os x but it said that i'm not connected to the internet,so i turned it off so i can turn the wifi on but it didn't turn on because i erased the hard disk.

    Now what i need to do?

    Sounds to me like you will need an install disk. You do have the Lion or iMac recovery disks don't you?

    reinstall

    1. Turn you iMac on
    2. Insert your recovery disk in the drive
    3. Press and hold the C-key on the keyboard until your mac boots up.

    4. Have cookies and milk during install to celebrate. :D

    If the iMac isn't powering on, you should completely unplug it from power for around 5 minutes. Plug it back in and it should be fine. If not, then try it again, but while it's unplugged, remove the RAM. Wait a minute, then reinstall it, and then try it. That has happened to me once where it would not turn on, but after unplugging it and removing/reinstalling the RAM, it was golden. It resets something, but I don't remember exactly what.

    Good point! And thanks for the correction.

    Valid. Think I was reading a bit to fast for my own good. You are correct that resetting the ram can also be the culprit. Also, I am not familiar with the innards of the newer iMacs, but unplugging, pulling the PRAM battery or equivalent might not be a bad idea as well, that way bad ju-ju that might be saved in a persistent state is also wiped clean.
