Kim, If it still booting into Mac OS X Utilities, then try this. Turn off your Mac. Hold down Command + Option + P + R keys and then turn on your Mac.
If that didn't work, then restart and hold down Command and R keys and this will boot into Mac OS X Utilities. Select Disk Utility in there. In Disk Utility, select your hard disk in left column, under First Aid click Repair Permissions. Then click Verify Disk and if asked, click Repair Disk.
Then restart your Mac. Please let me know how it goes.
