Will not boot or restore, but I can install and run Windows!
Hi people,
I'm repairing a 2008 24" iMac 3.06GHz, and see these issues:
Booting anything Apple, it freezes on the grey screen with the Apple logo and spinning wheel, halts about 1/4 through and the either just sits there or restarts.
Booting anything does not work. It will not boot OS X, Safe Mode, recovery partition, from a DVD or from USB.
However - I can pop in a Windows 7 DVD, and it will install and run great (!)
It will display the boot menu (hold Option key), and I can see the internal disk, the DVD in the drive, and all connected USB/FW disks.
It will start up in FireWire target mode, and I can see the internal drive from my working MacBookPro via FW.
If I put my MacBook into FW mode, I can see its disk via FW on the iMac, but trying to boot it gives me the same result as above.
Actually, the iMac has just corrupted my otherwise working MacBook HD, so I am recovering that machine as we speak...
I have replaced the logic board and the RAM sticks (confirmed working on another Mac that uses the same kind of RAM), tried another hard drive, but nothing helps.
The super-weird thing is that I can pop in a Windows 7 DVD, and it will install and run flawlessly.
So this tells me that the logic board, the display and graphics card and RAM should be working.
I have done PRAM/SMC and all that stuff.
Is this a good question?
