I have a MacBook Pro 15 on which I tried to install Ubuntu 20.04 as my host OS. However, the installation has failed. Whilst waiting for the Linux forums to help me out with the installation, I am trying to go back to macOS, but I am unable to do so.

Next, I entered Recovery Mode (Cmd+R), then selected "Reinstall macOS". However, when the software asks me to select a drive, I found no drives at all. So, I can not continue and complete the installation.

I also tried to restore the main drive from Disk Utility, but received the following error:

Can somebody please help me reinstall macOS on the MacBook Pro 15?

  • Do you have a backup of your data? If so, you might consider reformatting an nvme partition to APFS using disk utility and installing mojave there. I recently dual-booted mine with mojave and linux, and to do this I created fresh partitions from disk utility on a blank drive from recovery mode, then installed macos, then installed linux.

  • Post the output of diskutil list from Terminal in Recovery. i can't see enough of the left column in your second pic to try figure out what you've done.

You've probably corrupted your hard drive while installing ubuntu and messed up the info, so you need to get a new hard drive and replace it, or if you have a backup drive and backup computer install macOS Mojave on it, set it as the main boot, and don't remove it.

You can also take it to a repair store to get it fixed, or buy a new mac.

If none work (mainly because you can't buy anything, you're low on money, or have nothing other than the mac), you're screwed.
