Chosen Solution
I was using dual drive setting in my iMac late2015 27” (512GBSSD and 1TB hard-disk). My start-up disk was SSD and I was using hard-disk for holding data and storage. I was using Bootcamp’ed Windows as well without any problems. Now I’ve upgraded to Catalina, Bootcamp won’t let me install Windows stating the error; ‘Boot Camp cannot be installed to a split Fusion drive. In order to install Boot Camp please restore your drives to fusion’ I was not using any Fusion Drive setting to begin with…Why catalina is not recognizing my drives ‘dual’ but instead it recognizes them as ‘split fusion drive’. Can anyone help me?
Your volumes look a bit odd. I haven’t installed Catalina yet so I don’t know why it made a difference if you had already setup a dual drive config with BootCamp working. The only thing I can think of is this was a Fusion Drived setup but you hadn’t broken the fusion set before altering things. See if this allows you to break the config Split Your Fusion Drive Apart. You may need to scratch the drives and start afresh to get things working.
Hi, I found the same problem, after searching a lot I didn’t find any solution. AppleCare says me I should use fusion drive again… I really don’t like that solution… I have tried to format my 2 drives using USB boot restore Catalina, but Catalina is not recognizing my drives as individual drivers, instead it still recognizes them as split fusion drive, what is the problem? Maybe install Catalina on a external USB and use Boot Camp at Catalina HD will work?
