Windows won't start after trying to use Norton Power Eraser - eMachine Windows 7 64 bit

I tried to install norton antivirus suite, but received an error (boot.cidox) which directed me to use Norton Power Eraser.  After trying to use power eraser,  Windows will not boot in any mode.

Please, help,  I need this computer back up asap..

I've seen it fixed for another user... back in 2012.
