<p>If you have tried to repair the boot volume before in Mac OS X before, you’ll undoubtedly have found the “Repair Disk” option is grey and unavailable within the Disk Utility tool. While this is still the case while booted in OS X Lion, you <em>can</em> repair the Mac OS X boot disk thanks to Lion’s Recovery Partition, preventing the need from using an external boot drive to repair the disk.</p>

Once booted into Recovery mode you’ll find the limitations on Disk Utility’s repair function has been removed, here’s how to do that.</p>
