Hi. So I’ve made quite a mistake and accidentally deleted the Mac OS from my Mac during a boot camp and I’m left with just windows now. The recovery mode is not working now and it boots right into windows. I have a time machine backup. Can someone please advise what to do. I need to get Mac OS back. I don’t mind if I lose windows.
Hi all. I found a fix! It was not malware or any such. So if you every accidentally reset Windows from the Windows boot camp it will install a non-boot camp version of Windows so you won’t have any of the options to switch between the operating systems but I found a way to get back to Mac OS. In Windows open settings and search for “boot” Then press advanced boot and then press restart. Once your into the advance boot there should be a few options to chose from, one of which is booting from a USB. Select that and make sure you have no USBs plugged in. There should be a drive with no name just an icon. Select that one and then hit enter and in my case that booted me right back into Mac OS. Seems like it was a back door into Mac OS. Hopefully this helps anyone else! On the boot camp I was running Windows 10 and on my Mac I was running Catalina and my computer is a 2019 27” iMac
You should still have the hidden recovery partition. Are you sure you can’t get to it? You may need a USB keyboard if you have a Bluetooth keyboard.
