volume won't mount for main user-intel imac with mountain lion-what to do?

After logging in to admin user, grey screen with spinning arrow

Can login to Guest User but that is just set up for Safari only

Tried starting in Safe Boot, zapped the PRAM, removed all peripherals, rebooted with installation disk and used Disk Utility - disk greyed out and says not mounted


How can that be?


this is an Intel-based iMac purchased last summer, recently installed Mountain Lion

iMac, OS X Mountain Lion

I have the same problem. Installed Mountain Lion, got the spinning orb with no escape so I powered down. Upon re-boot I have the dreaded "?" Tried restarting several times to no avial.

In desperation, I inserted the 10.5 (Leopard) disk to install the original system version that came with my iMac. Now the install disk cannot find or mount my hard drive. I'm stuck.

Anyone??
