[QUOTE="chscag, post: 1653253, member: 46727"] Do you have a boot disk that you can use? I'm not sure if your 2012 MacBook Pro came pre-installed with Snow Leopard or Lion. You should try booting from an external source if possible. That can be a DVD or a USB flash drive. The fact that Disk Utility says your hard drive is OK does not mean it is OK. Disk Utility does not check everything. If you do have an external source to boot from and it still doesn't boot, try removing the hard drive and see if it will boot. Also check the SATA cable from the hard drive connector to logic board as they are know to fail from the heat build up. [/QUOTE]
