When updating macOS Big Sur to the Monterey version, the system hung at some point, started the installation again, the same thing. Through shift+option+command+r it is possible to rollback to OS Catalina, when trying to reinstall Catalina does not display the disk for installation, when the disk is visible for installing BigSur but it is not installed, what is the solution?
