Part 1[br]
+
+
+
At first windows didn't want to install and crashed with errors but at some point it installed. I realize it sounds abstract.
+
+
After installation windows works as it should. but in the menu where there should be a button to go back to mac os it is not there. the firmware password is forgotten by the seller (used mac) and when you press command + r + power there is such a lock with boot. it is unlikely that it should be so. and I absolutely do not know what to do. The only option was to remove the RAM with the battery off, plug the battery in, turn the macbook on with the buttons pressed to reset the pram and it would reset the password. but the problem is that the memory is soldered in. Maybe someone has encountered this problem I will be grateful for any help. I found similar topics on the Internet, but those who asked this question remained unanswered. unfortunately.

Part 2 [br]
It all started when I installed windows through bootcamp assistant. I bought an adapter for macbook ssd, plugged it in, deleted the boot windows partition, and subsequently all the partitions that had windows on them. This did not help at all. Then I formatted it completely and that didn't help either. In all cases I have this situation on my screen. Everything is on the video. I have not found anything like this on the internet, maybe someone who has encountered this and can advise. I've tried pressing all sorts of hotkeys at startup, as well as Option-Command-R or Shift-Option-Command-R to get into macOS Recovery, but I still get thrown back to this screen, which I understand is broken, because again, as I understand it, this boot icon should not be there. I'm attaching the video. I would be grateful for your help.[br]
