Hey there!


You should be able to go back into Disk Utility.


On the top menu select View > Show All Devices.


Then under Internal, select the main SSD/HDD/Fusion Drive > Erase > Erase again.


Before erasing, you can re-name the volume, (Normally Macintosh HD, but it can be changed).


Next, you should be able to Quit Disk Utility, then again try to Reinstall MAC OS.


This time you should see the normal Macintosh HD, (Or whatever you re-named the volume).


Hope that helps!
