Multiple internal volumes

[Suffa]

I have a MacBook Pro 15” mid-17, 256GB. I’m about to sell it so I went into disk utility and deleted all the volumes. That was a mistake as it did not boot at all after this, and the internet recovery didn’t work either. Managed to boot it and reinstall OSX using an external drive.

Now, however, disk utility looks like this:

And I can’t seem to erase any of them either, they just reformat and come back.

What the F is going on?!

Cheers

I think you need to completely erase the internal drive and start over.

Try this:
1. Boot to INTERNET RECOVERY (NOT to "the recovery partition")
Command-OPTION-R
at boot

2. You'll need your wifi password. Be patient "as the globe spins".

3. When you get to the internet utilities, open disk utility.

4. VERY IMPORTANT STEP: go to the "view" menu and choose "show ALL devices".

5. Now look at the "list on the left". The topmost item should be the internal drive.

6. Click on it to select it, then erase it to "APFS, GUID partition format".

7. When done, quit disk utility and open the OS installer.

8. Start clicking through. The Mac will reboot one or more times, and the display will go dark for a minute or more, with no other indication of activity. Just be patient.

9. When done, you'll see the initial setup screen (choose your language).
At this point, just go to the menubar and quit the setup app.
If there's no "quit" available, PRESS AND HOLD DOWN the power button continuously until the display goes dark and the Mac shuts off.

10. It's now ready for the next owner. When it boots again, it will boot right back to the setup screen, just as if it were new.

PRINT OUT this post and keep it for reference.

Hi there!
Reboot your WiFi router and place your Mac next to it.
2~ something errors, are internet-connection related.

You might also try opening your wifi network so no password is required. Often that error is because you are using a wifi security protocol not supported by Internet Recovery.

So bizarre. I tried changing DNS, open the network but none worked. I had to use my iPhone as a 4G hotspot and then bam it worked. Why wouldn’t it work on my normal WiFi? It’s not like i have any unconventional settings on the network..

How do I delete these to not get the same issue as before?

Last time I deleted all the volumes, the computer didn't boot at all, just a flashing folder with an error.

Follow starting with step #4 in post #2 above. That will wipe the whole drive so you can start fresh.
