Hi, H.
It sounds like you ran Live Verification, i.e. used Verify Disk against your startup disk while booted from such. One can Verify, but not Repair, the current startup disk.
Run the Procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
If Disk Utility still fails to repair the disk, see the "Disk Utility cannot repair the disk" section of that same FAQ.
Good luck!
