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
