You are describing what appears when your computer boots into the Recovery Partition and not what appears when you download an OS upgrade. Before we go any further I need to know what you are doing to get there. In other words, did you restart your computer and this screen came up? Were you pressing any keys? Describe the events that led to your seeing this screen.
...part II
Yes, I rebooted and yes I press the notebook mouse and the on/off button, because it wasn't restarting for itself... So when I turn on my notebook, first appears the window of the language and then this window that I described, the macOS Utilities. ;)
If you got to this screen without doing anything but restarting then I suggest that you first select the Disk Utility option and run it to repair your hard drive. If it completes that task without complaint then select the Reinstall MacOS option.
Okay, thank you! On the Disk Utility, I have four things to say. First, it shows I have two tips of disk, one is internal, that have 2 in it, and the other is disk images, that have 4 in it. The name of the internals are HGST HTS541010A9E680 Media (capacity of 1 TB, 1 TB SATA Internal Physical Disk) and Macintosh HD (capacity of 999.35 GB, 999.35 GB SATA Internal Physical Volume Mac OS Extended (Journaled), the use is 176.3 GB, Purgeable: Zero KB and Free: 823.04 GB) and the names of the Disk Images are, the 1st is Apple disk image media (2.15 GB Disk Image External Physical Disk) Use: 2.01 GB the 2nd is OS X Base System (2.01 GB Disk Image External Physical Volume Mac OS Extended) Used: 1.3 GB, Purgeable: Zero KB, Free: 710.8 MB, 3rd Apple disk image media (5.83 GB Disk Image External Physical Disk) Use: 5.48 GB
and 4th OS X Install ESD (5.48 GB Disk Image External Physical Volume Mac OS Extended, Used: 5.02 GB, Purgeable: Zero KB, Free: 458.5 MB.
The option, you said repair, it doesn't have... The options are First Aid, Partition, Erase, Restore, Unmount and Info. And the difference between the first apple disk image media and the third apple disk image media is that the first is called OS X Base System and the third is OS X Install ESD.
The 4th thing I have to say is what's the next step?
Thanks for your time!
Amy.
I don't know why... But I can't repair, after I clicked on first aid it shows a window "Running First Aid on Macintosh HD"
First Aid could not unmount the volume for repair. Click Done to continue.
And I don't know if I could do that but I clicked to repair the other disks and it worked... And what happens if I erase one of these disks? Thank you again ;)
Hey, DWB! This seems very stange... I was having a separate issue and I found this thread because of a similar issue. I just rebooted in Recovery Mode holding Command R after installing a brand new hard drive. In Disk Utility my new hard drive shows up in the Internal section, as it should. However, there is a section below that I have never seen before labeled "Disk Images" and then there are 2 separate images, like Amy described above. One says Apple disk image Media, 2.15GB Disk Image External Physical Disk and below that the other image says OSX Base System 2.01GB Disk Image External Physical Volume Mac OS Extended (it appears to be ejectable, the eject icon is to the right).
I don't have any external devices plugged into my machine. What are the Apple disk image and OSX Disk Images? I'm baffled right now and curious if this is causing an issue.
Thank you
Yes! I rebooted!
I assume that you are booting from the Macintosh HD. That's the one to repair. Apple changed up the language a bit - First Aid = repair
Sometimes when a disk won't unmount a reboot will solve the problem. Restart holding the command R key to restart in the recovery partition. Then try again.
Also - what mac model do you have?
It's the Mac OS X 10.9.5
Not the operating system - the computer. iMac, Mac Pro, MacBook AIr, etc
Oh sorry, MacBook.
And the DVD drive was replaced by a 2nd HHD?
Have you tried restarting the computer while holding Command R and then doing disk first aid?
Sierra update issue - Which do I choose?
