Choosing boot disk from within windows?

[lilbiscuit]

I have a flashed MacPro 2009 (4,1 to 5,1) that is an awesome machine, 12 cores etc etc. I use OSX and Windows regularly.

But with no boot screen, I can't reliably choose a boot disk on startup. I basically have to guess (2 right keys then enter for OSX) but it doesn't always work.

Obviously within OSX I can select the boot disk to reboot into Windows. But once in Windows sometimes I get stuck there (like right now).

Is there any Windows software that will allow the selection of the boot disk? Within Windows I run MacDrive to be able to access the Mac formatted drives. Right now it's seeing the Mac drives as corrupt (I have removed and confirmed by connecting to my MacBook that the drives are fine) so potentially such software wouldn't even work at the moment. But does it exist ?

I was think the BootCamp drivers had a app for Windows that allowed you to choose the macOS as a startup disk, from within Windows, but no support for APFS disks, as far as I know.

You should still be able to download the drivers for BootCamp and write them to a flash drive to install in Windows.

If you install the BootCamp drivers and Paragon HFS+ you can use the Boot Camp Control Panel to switch disks. However Paragon HFS+ doesn't work with APFS. Hoping Paragon will come out with Paragon APFS for Windows.

I will give this a shot. THX!

Pretty sure Paragon HFS+ is not required to make the bootcamp control panel work.

My free version of Paragon HFS+ doesn’t work with the current Windows 10 creator update. But the bootcamp control panel can still select the 10.13.1 HFS+ boot partition.
