I am trying to reinstall OS after erasing HD, and reinstall can not find a disk to install on to. I think I may have erased too much? But I did not "unmount" the HD
iMac 21.5″, macOS 10.15
If you can boot to the Recovery HD, Restart the mac while pressing and holding the Command and R keys.
Open Disk Utility, press Continue.
In the left panel highlight the uppermost Disk not the indented Volume.
Click Erase.
Give the Disk a name.
Format: Mac OS Extended (Journaled)
Scheme: GUID Partition Map
Click Erase.
When Done quit Disk Utility.
Now try Reinstall OS X
