everytime i try to boot installation a message appears saying 'you need to restart your computer. holddown the power button until power is off then press down power button again'. i read that it was a kernel panic. cant boot into any modes but recovery mode with disk utilities but my wireless internet says no wifi hardware installed and sometimes startup manager. this just started after i erased the hard drive and had it overwritten with zeros. its a macbook pro 7,1. bought it in 2011, i think it was made in 2009. it has 320 gb of empty space right now and nothing ive tried seems to work. please help!!!! there is also no os x installed right now due to me zeroing out the hard drive how do i repair it so it will boot to installation?? i can also enter single user mode but do not have root access?

MacBook Pro
