Oh yeah! I would have had you format the disk first, but hopefully it is already formatted properly and this will work.I presume that's a good thing
Let me know how you make out.

@Weaselboy to the rescue again!All working fine. Already update ios. All good and working. Thank you very much for your help.
When you boot are you seeing a spinning globe first before you get to the recovery screen?Will someone please help me, I also have the same problem. I am running mac os high sierra on a MacBook air and I tried to erase the contents of my mac for a fresh start. I accidentally deleted my "Macintosh HD" drive and now it has disappeared from my disk utility. I tried the commands in the terminal from previous pages but It said that I have no core volumes on the mac. I have a time machine backup, but I can't restore it because the mac no longer recognizes my internal drive. If I hold option on startup, it allows me to boot with the internal drive but it won't show in disk utility.
Sometimes yes, but other times it usually just automatically boots into the internal drive, it shows the no entry sign but I can still access the recovery mode.When you boot are you seeing a spinning globe first before you get to the recovery screen?
Okay... once you see the spinning globe then it gets to the recovery screen, can you see the internal disk in Disk Utility?Sometimes yes, but other times it usually just automatically boots into the internal drive, it shows the no entry sign but I can still access the recovery mode.
diskutil list
diskutil cs list

Also while in recovery, go to the Utilities menu and open Terminal. Then enter the two lines below one at a time and tell me the output of each command.
Code:diskutil list diskutil cs list
That base system is a virtual image in memory and is the recovery volume you are booted to.No, I can't see the internal in the disk utility, only a disk image called OS X Based System
I typed in the two commands, the first one showed the internal disk as a GUID_Partition_Scheme but it was called disk0
the second command showed "no corestorage logical volume groups found"
Hmm.. odd we can see it in Terminal.Unfortunately, even after doing that, it still only shows the OS X Base System. Thank you for your help so far by the way.
diskutil eraseDisk HFS+ "Macintosh HD" disk0

While still in Internet recovery, go back to Terminal and enter the above line exactly like I have it including the quotes. That will wipe the whole drive back to the old format. Then go ahead with the install. You can convert to APS later if the HS installer does not do it for you.
I am going to reopen internet recovery but I might have to get back to you tomorrow because the internet in Australia is really slow. It says 20 minutes but last time it took about an hour.If you are sure you are in Internet recovery (saw the spinning globe first?) then I am getting worried you have a failed drive.

Sounds like you might have a drive starting to fail. You might try a disk first aid run in Disk Utility to see if that shows any errors.Update: I don't know why, but the install finally worked. I tried multiple times to mess with options in Disk Utility and for some reason it finally let me partition and worked. I directly went to installing the OS after that and it did so properly. No total explanation why other than keep trying to Erase the disk and it might randomly work eventually.
