Mac Professional Bootcamp Problem – Ask Totally different

I’ve a MP 3,1 with an ATI Radeon RX580 8GB Graphics card, a dosDude Catalina (10.15.6) set up on an inner SSD and and a Home windows 10 Professional (Newest Model and updates) set up on an inner HD. Each the mac OS and the home windows work superb together with all components of the mac. As I a have the Radeon card I don not have a boot display till both Catalina has largely began up or home windows has began as well so I can’t change the booting by holding down the choice key.

I beforehand ran El Capitan as a substitute of Catalina and with that I had put in in Home windows the boot camp four drivers, which allowed me to pick out Mac OS from the boot camp assistant and reboot from Home windows into El Capitan. From El Capitan I may choose the Home windows drive within the begin up disc management panel and reboot into home windows.

Nevertheless since upgrading to Catalina I can nonetheless choose the Home windows drive within the begin up disc management panel and reboot into home windows. Nevertheless if I choose Mac OS from the boot camp assistant and reboot the Mac, it all the time reboots into home windows.

My present work round is to close down, take away the Home windows drive, reboot in to Catalina, choose Catalina within the begin up disk management panel, reboot into Catalina, shut down, re-install the home windows drive, begin up an it begins up into Catalina once more with the Home windows disc mounted. I can then simply choose the Home windows drive within the begin up disc management panel and reboot into home windows after I have to.

From what I’ve learn it is a difficulty with boot camp not liking the APFS file system Catalina makes use of. I’ve additionally learn {that a} newer model of boot camp would repair the problem. I’ve upgraded boot camp to model 6, however this trigger different points in Home windows and in the long run I needed to format the home windows drive and re-install it from scratch together with the boot camp four drivers.

Can anyone inform me how I can get this problem sorted out so I can simply swap utilizing boot camp?

Many thanks
