Accidentally Deleted Macintosh HD

I Accidentally Deleted Macintosh HD while trying to clear out my hard drive. OS X BASE System will only appear under the tab (disk images). And the internal tab only has a something named untitled. I’m completely lost. I’ve googled and YouTubed everything nothing is working. I tried to reinstall macOS and input the date year time into terminals not working. I really need help.


MacBook Air 13″, macOS 11.5

OK, thanks! Let's try this:


  1. Start up from macOS Internet Recovery: Turn on your Mac, then immediately press and hold these three keys until you see a spinning globe: Option, Command (⌘) and R. 
  2. From the utilities window, select Disk Utility and click Continue.
  3. In Disk Utility, select View > Show All Devices.
  4. Select APPLE SSD SM012... in the sidebar of Disk Utility. 
  5. Click the Erase button in the toolbar, then enter the requested details:
    1. Name: Macintosh HD
    2. Format: APFS
    3. Scheme: GUID Partition Map
  6. Click Erase, then click Done.
  7. When done, quit Disk Utility to return to the utilities window, and select "Reinstall macOS".


If you have any questions, please let us know!
