Hi, I have an early 2008 IMac running 10.7.5 that I'm upgrading the hard drive on.  I used Carbon Copy Cloner to clone the original 320gb drive to a new

Seagate Barracuda 7200 1 TB 7200RPM SATA 6 Gb/s NCQ 64MB Cache 3.5-Inch Internal Bare Drive ST1000DM003.  After successfully creating the clone, I was able to boot from the new drive via a USB enclosure.  I used the "command+option+R+P" meathod to select the new drive in the enclosure.  Next, I installed the new drive into the IMac, and verified that all cables were securely fastened.  Now when I turn on the IMac, I get the flashing grey folder with the question mark.  I'm unable to get any of the boot-up commands to work, for example: "command+option+R+P" or holding down "option."  I've even tried putting the old drive into the enclosure via USB and the new drive into the IMac with no luck.  I still can't access the screen that lets me select the startup disk.  The only thing that works is starting the IMac with the original Install CD.  With the Install CD, I can see the new drive with Disk Uitlity, but it won't let me select it for startup.

 

Thanks for your help!
