What can I do if my iMac boots with a question mark?
I purchased an older iMac a few weeks ago, because I couldn’t afford a MacBook Pro.
I don’t even know if the stats I listed are correct. This is what i do know:
8 GB memory, it’s 27” from corner to opposite corner and it’s a 2009,
In addition I finely found a great deal on eBay last week, and purchased a mid 2012 MacBook Pro.
After I got the MacBook Pro, I removed the HD, and used it as the drive to make a time machine full back up of my iMac.
The iMac I purchased was struggling with speed and I had my new (to me) MacBook Pro with an SSD and 16 GB of RAM, so I thought I would format the drive to free up some of the 220 of 250 GB I was using. I was only planning on using it to watch Sling, web surfing and listen to music. But, after I formatted, it wouldn’t load High Sierra on its own.
I downloaded High Sierra on my MacBook Pro, and used the command in terminal to install High Sierra on a USB thumb drive. It wouldn’t load from startup on the iMac, then i clicked startup disk, and clicked to install there - it did, and then when it rebooted, it will only show a question mark on the screen, I rebooted a few times,
I then I had a ridiculous idea, and decided to throw a copy of my Windows 10 CD in the drive, to try and get to a command prompt or anything other than a question mark - but it didn’t do anything , no surprise. hindsight is 20/20. I can’t eject the cd, and can’t get to terminal.
I have been messing with this thing for 2 days straight now.. The only thing that I’ve been successful at was getting the CD out of the drive - Thanks Dan! Holding the mouse button worked.
Before I ramble on with the struggles I've had, I want to say this - When I purchased this iMac a few weeks ago, it had High Sierra already on it. Apple was as surprised as you all where when I called about a technical issue I was having a couple days in they wouldn't help me troubleshoot it, because of that reason.
Now for my trials and failures!
I have tried to install El Capitan, Mountain Lion, and High Sierra - on my 32GB USB and my 500GB 860 EVO SSD, with no success.
I’ve followed instructions on all, but the furthest I can get is a screen with a lock requiring a password.
I only have a PC Windows keyboard, but through all of my investigation I learned that the Windows key, is the command key on a Mac keyboard - but I have also tried many other options to boot from the Apple Site.
Is this a good question?
