How to fix " Could not create a preboot volume for APFS install " on Mac OS .


A lot of people are facing this type of problem.

Some MacBook users are concerned about upgrading to macOS High Sierra,which 
offers the new APFS (Apple File System) that replaces the nearly 20-year-old HFS+ filesystem. 

APFS offers a lot of advantages for SSD performance and durability, as well as encryption for any type of drive. But it’s not backwards compatible with older versions of OS X or macOS.

This APFS creates a problem while a clean install of MacOS High Sierra i.e "Could not create a preboot volume for APFS install ". 
So here I am going to show you how to fix "Could not create a preboot volume for APFS install" on MacBook.


First don't try to install macOS High Sierra again.


Delete your drive until you have no drive.


To do this, power off your Mac and then hold command + R and boot up your Mac. This should do the trick.

Select the " Disk Utility " option. 

 Then delete your drive in disk utility by clicking the minus button on the top right .



and then enter internet recovery mode by repeating the process though this time adding option and then command + R. 
It will take some time and then you will enter the same menu which is macOS Utilities.

 Click on "Disk Utility " option and format the disk as format type " OS X Extended 

 (Journaled) " and Scheme " GUID Partition Map ".



and then return back to macOS Utilities and click on the " Reinstall macOS " option. 

 The fix is your removing the APFS system which is what is confusing the drive which for some reason apple can't figure out themselves . 

This time instead of Mac OS High Sierra you will just see macOS Sierra. 
Then just click install Mac OS and you should be good to go.
I hope it will help and ask anything you need.

THANK YOU.

      Sorry for this.
      Instead of formatting the APPLE SSD SD... , format the Macintosh HD.
      I think it might work and let me know if it works for you.

      Hi- I had this same problem and I tried to format the Macintosh HD but it does not give me any other option than to format it as APFS.

      Any help on this?

      Boot up your mac by holding option along with command + R , you will enter internet recovery mode and then select Disk Utility .
      Here you will be able to format your disk.

      Open Terminal and type following:
      diskutil eraseDisk jhfs+ Macintosh\ HD disk0
      It will wipe your HD, create a GUID scheme and format it to htfs (Mac OS journaled)

    Thanks for the tutorial! When I try to use it though, it is will not working, and my Mac refuses to proceed with the option to format the disk as "OS X Extended (Journaled)" It also does not give the option for the Scheme "GUID Partition Map." Do you know why this may be?

    Would you let me know what exactly the error you get while formatting the disk as "OS X Extended (Journaled)" and also what are the options available in "Scheme"?

    For anyone having trouble deleting the drive, I had to boot into internet recovery mode (option + command + R) to delete and create a new drive. It won't let you delete the drive if you boot up with command + R because recovery mode is using that drive.

    @Serdar720 I have a 2009 iMac which is too old for internet recovery option,so I'm using recovery from a local drive. I've installed a new SSD and tried Terminal diskutil, but it says "failed to unmount" any way around this?
