Hello, I wanted to reformat and do a fresh install of macOS High Sierra as i will be giving the mac to my sister.

My process was Going to the CMD+ R screen

Going to Disk Utilities

-Erasing Macintosh HD

-Rebooting and going back to CMD+R screen again

-Clicking on install macOS

-Clicking on install High Sierra

-Once the process reached 100%, I got the error “could not create a preboot volume for APFS install”

Now I am unable to install a macOS any help please? iam using MacBook Air 2017? also i tried to change Maconitsh HD to Mac extended Journal instead but i dont have that option just all AFPS related.
here is a pictures from the disk utility http://ibb.co/nCQTYn

thanks!

If using the High Sierra disk utility, click on all devices, and try staying every partition first to see if that helps.

the only thing i was able to delete is "Macintosh HD" when i try to delete "container disk1 or apple SSD SMG 0128 Media" the "-" sign is greyed out
 
Do you have access to another Mac to create a Sierra or El Capitan installer?

Either operating system will format the ssd back to HFS. It may take a couple of tries to format with Sierra or El Capitan but it should bring it back to HFS and then you can install High Sierra.
 
Bro how did you this? I have the same problem. What is this bootable usb? I dont have any back up.

Did you try pursuing the power button and hosting down command+option+R keys to enter internet recovery?
 
I had the same issue but on a Mac Pro. I downloaded Sierra and made a bootable usb which formatted the drive to HFS and then did the upgrade to High Sierra.
 
I just solved this problem. Somehow, the partition (volumes) got messed up in the new Apple File System. So what I did was reformat it to MAC OS Extended (journaled)—I guess that’s the old file system. Then I reformated it again back to APFS and installed High Sierra. That’s all without a bootable USB
