Why is a flashing question mark on my iMac's screen at startup?
I have the following problem with my iMac 24” 2.33 GHz, 2GB, 500GB HDD.
At startup I get a flashing folder with a question mark. After trying everything I found online with no success,
In Target Disk Mode I was able to access the drive and wipe it off. I have the original install disk, but it doesn’t let me install OS-X, extended hardware test shown 0 errors.
In hardware profile-video it says Graphics: “unknown video”.
Any help would be highly appreciated.
I’ve tried this before but it doesn’t boot, I can’t get to disk utility because I receive this message, I restart and nothing happends.
