iMac operating system not found repair Frisco TX

Apple iMacs are a good computer for everyday use. However, there are still cases wherein some owners are experiencing hard drive issues. Just recently, one of our customers encountered the “Question Mark” boot-up when he turns on his iMac.

According to him, he didn’t experience any data loss or anything related to it. His computer just wouldn’t go past the “Question Mark” boot-up screen. No matter how many times he turned it off and on again, the same thing happened. Fortunately, we were able to help him fix the issue and his iMac is now working correctly.

This particular problem is usually caused by an incorrect setting in the System Preferences. To fix this, you’ll need to open up the System Preferences and select the “Startup Disk” preference pane. Once you’re there, simply select your main hard drive as the startup disk and restart your computer. This should fix the problem and allow your iMac to boot up properly.

This could be due to the faulty hard drive or corrupted OS as well.
