Unable to boot up in Mac OS

I recently used bootcamp to change the operating system to windows on my iMac. However now when I enter the startup it no longer has the option to start up in Mac OS, only windows.


Also cannot seem to find the bootcamp app as I’m stuck in windows and it is not located in the task bar or hidden apps/icons


how do I get back to run Mac OS because I no longer want to use windows.

iMac (M4)

It sounds like you did not actually use boot camp to partition the drive and install windows... Or you tried to repartition something after installing Windows. You no longer have a macOS partition.


Try booting into recovery mode, erasing the drive completely, and reinstalling macOS from the internet.


Hopefully, you've been making regular backups.
