iMac 24" USB boot up and crashes at installation
Ok I got a 2nd hand imac 24 - 2211 - A1225
I can usb boot with multiple OS X retail versions. I can go to disk utility and partition hard drive read usb contents and see super drive all day long with no problems. Once I click install, it will start analyzing. it will say 30 mins. Then boom immediately black screen. I have to hold power button to reboot it.
What is the cause of this?
