start boot

Open core legacy start

I have installed mac os sonoma on my macbook. and when I start it I see these disks after pressing alt first. I have to say that I had a windows partition of bootcamp. and everything works fine. but I want the startup to continue appearing as before. macintosh HD - windows partition. to enter windows or mac os I have to press the windows open core legacy icon and then start windows or mac os sonoma in the second picture. how can I fix this? I have read that there is an option in the open core legacy application to remove the open core symbol. but since I also have the windows partition I don't know if it will work. thanks
