Accidentally turn on Raid set to increase space on my MacBook Pro. Now, I can’t install osx neither delete raid.

How can I run Disk utility from an external drive?

Thank you

If your Mac was issued after 2010, you use Recovery mode to load the Utilities that "in the old days" were provided on the MacOS release DVD. Hold Command-R at startup.

It creates over 20 RAM disks to store its temporary stuff, so it can avoid using the Boot drive at all, leaving it COMPLETELY free to be completely erased.
