Open Disk Utility & select the hard drive from the list (not the name of the volume indented under it).
At the bottom of the window, you will see a line of info that tells you the Partition Map Scheme of the drive. It should be "GUID Partition Table."
Is it?

In Disk Utility select the volume & click the Verify Disk button.
If it reports any problems, follow the instructions at the top of the window to restart from your installer disc & run the Repair Disk step.

Also post your specs plz like tattooedmac asked, it will make it easier for us to give a proper response.

Also, I'd advize you that if this does not work, check what the update is doing for your system, like in big important
If it doesn't have them, consider skipping this one and hold out for the next one.
A lot of people are experiencing issues after this update
