Cannot boot. Apple logo and pinwheel just hangs
Thanks for reading.
I have an iMac that is 2005 - I think. 1Tb, 4Gb, upgraded to Core 2 Duo.
Turning the Mac on the Apple logo appears and the pinwheel rotates - and that's it.
I have tried all Boot options like Shift, C, T, Command-R+P, etc etc and still all I get is the same. (all after the ding sound). I have also taken the drive out and connected it to an external caddie, and then to my Macbook Pro via USB. I can see all the files fine. It just will not boot inside the Mac. I'm afraid I cannot recall what version of OS X it has sorry but it was whatever the latest and maximum was for that machine with core 2 duo.
Is there a way of reinstalling the boot sectors ? (I am talking PC lingo, no idea if that translates to the iMac)
Any help / suggestions would be appreciated.
thanks
iMac
