How can I reinstall macOS Sonoma from recovery after deleting Macintosh HD in Disk Utility?

My MacBook Pro M1 Max 2021 froze for over 12 hours during a recent update and I had to start it in recovery and erased everything (including Macintosh HD volumes.


Now when I try to install MacOS Sonoma from recovery the internal SSD does not show up as an option at all.


The diskutil list command in Terminal (in recovery mode) lists 3 different disks and I can’t erase any of them because they seem to be in use in recovery?


/dev/disk0 (internal, physical)


/dev/disk3 (disk image)


/dec/disk4 (synthesized)


When I try to erase the entire internal APPLE SSD volume it can’t unmount disk0 because it’s in use by process 0 (kernel) and I also can’t erase or unmount any of the individual disks because they seem to be in use too.

use Option-Command-R or Shift-Option-Command-R to start up from macOS Recovery over the internet.


 macOS Recovery installs different versions of macOS, depending on the key combination you use.
