Hello, Just the other day i was getting the status bar showing on the boot screen, and very s.l.o.w. boot times. After a number of re-boots my imac 2011 10.7.4 would not boot at all. I ran Disk Utility/ Repair disk and was told it could not be repaired, so I was forced to reformat and restore my HD (original internal 500G that came with computer). It's working fine now, and I'm glad I belong to the camp of "backs their stuff up semi-regularly." Anyways, I just noticed that the Recovery Partition does not show up at all when I boot while holding down 'option' key. It's as if it was never there. When I did the restore, I used Super Duper, and I only reformatted/restored the main partition, not the whole HD. any suggestions to remedy?
