Is there any way to get the Bootcamp Control Panel (in Windows, while running on a Mac via Bootcamp) to somehow “rescan” for all the available startup volumes?
A few months ago, I installed an SSD in my 2012 Mac Mini, with the idea that it would replace the existing internally mounted spinning HD. In addition, I purchased the necessary hardware from OWC that enables me to have both drives installed inside the Mini, so that is the state of things now. As I was running MacOS 10.14 Mojave at the time, both Mac partitions are APFS formatted, and as such are not normally visible to Windows via Bootcamp, except for the Bootcamp Control Panel.
I was able to transfer everything from the old spinner to the new SSD, and thanks to Winclone 8, was able to clone the old spinner’s Bootcamped Windows partition to the new SSD. Long story short, all four partitions are bootable and run properly. I can select from all four partitions in the MacOS’s System Preferences > Startup Disk panel, AND I am able to select from all four partitions when I start up holding the Option/Alt key. The only issue that is problematic, and I admit is more of an annoyance than anything else, is that in those times when I am running Windows, having previously selected the SSD’s Windows partition in the MacOS’s System Preferences as Startup Drive, I cannot perform the corresponding preference change back to the SSD’s MacOS partition from the Bootcamp Control Panel. The MacOS on the spinner shows up there, but not the one from the SSD - and it would be nice if I could somehow get it to do this.
I thought that it might somehow fix itself if I simply disconnected the spinner HD inside the Mini, but this is a really finicky job that I’d rather avoid if at all possible. Has anyone else experienced something similar and come up with a solution for the “missing MacOS startup partition” issue I’ve described?
