My intel iMac's hard drive died so I installed a new one and reinstalled using the start up discs that came with the IMac and then installed snow leopard as that what was running before the HDD died and was necessary for restoring via Time Machine. The restore seemed to be working well when I went to bed but upon waking it had restored more than 100% and literallly said it would take MILLIONS (if not billions, there was a lot of digits) of hours to compete the restore. I stopped the restore but the machine wouldn't start, it keep telling me to hold the start button and restart the machine. So I tried to restore again with the same (100% + tons of hours) and the machine doesn't boot up (again tells me to restart again and again). I am re-installing SL now. Any suggestions?
