Sorry if this is not in right sub-forum

I have a 2012 MacBook Pro. Whenever I try to boot from my bootable USB( OS X Lion), it displays a stop sign.

Also, I have wiped off the HDD, and whenever it turns on, it shows a folder with ?.

Solutions? Thanks

A 2012 MBP shipped with OS 10.8 Mountain Lion, so OS 10.7 Lion is not supported.

You could restore to OS 10.8 using Internet Recovery (hold keys command+option+r at startup).

Which version of 2012 MacBook Pro do you have? The non-retina models, and the 15" retina, will start up from 10.7.5, but the 13" Retina (late 2012) requires 10.8.1.
As suggested in the above post, try internet recovery.

In that case, there's probably something wrong with your USB installer. How did you create it?
I used this USB lion to install before on another mac and it works. But i don't know why it doesn't works on this. I'm starting to think it's the hard disk that's faulty. Also I have the issue whereby whenever I used internet recovery to download reinstall OS X, it says request time out.

Thanks everyone for chipping in. I found the solution after a call to Apple. Apparently, I got to create another partition, and this is done so within disk utility. Seems strange to me when I thought it's possible to just install on it after erasing the whole HDD. Thanks
