Is Installing MacOS then Bootcamp Windows 10 Pro Possible

[ShintusMaximus]

Evening, folks! I'm going to attempt this in the next week or two with my new PC build. My plan is to install MacOS then Bootcamp Windows 10 Pro onto it too... is there a way to do this through Clover instead?

Bootcamp does not work on a PC-Mac build. See the guide.

Thanks, much appreciated. I'll probably follow the suggestion to install OSX first then use DiskUtility to sort out the drive partitions prior to a Win 10 install.

Really recommend you use separate drives. Installing on the same drive is asking for trouble and down the road come update time for Win10.

That's the plan, I have two M.2 SSD cards en route. I will try to use Disk Utility to format one exclusively for Windows, unless there is a better way of doing it?

Use the Win10 installation media to open a command window. Use diskpart to format the Win10 drive and create the EFI partition, then install Win10 to the unformatted partition (rest of the drive). The installation app will format the rest of the drive during the installation process. You want to use diskpart to create the EFI partition so it is the first partition on the drive begore installing Win10.

I've not used diskpart before, so the next in my series of dumb questions is -

Is this the process I should follow to achieve this on my 1st M.2 drive?

And should I assume that the 2nd M.2 drive will not require this when I install OS X through the bootloader?

How large is

How large is your Win10 m.2 drive? If you lack knowledge of diskpart and are not comfortable with it, and the m.2 drive is 1TB or less, then it is easiest to first format the drive with Mac OS disk utility, selecting MSDOS FAT as the partition format.
Then, when you reach the Win10 install screen where you select where you want to install, delete the FAT32 partition, leaving the drive with an EFI partition and free space, select the free space and click next. The Win10 installer will create and format the required partitions.

It can be made to work with OpenCore. But there's not much point. The only benefit as far as I can tell is that it lets you run Apple's Windows utility that sets the boot disk for the next boot.

Installing on the same drive is asking for trouble and down the road come update time for Win10.

OC since 0.5.8 has a bootstrap.efi file you can set up that is supposed to fix this. I've installed it on one of my systems, (the process is nearly automatic) but it was just to try that out, since I had separate drives.

Both m.2 drives are 1Tb in size. Neither drive has any content on it, both are brand new. The machine will be a new build with no existing OS - parts arriving early next week.

My intention would be to dedicate a 1Tb m.2 drive to OS X Catalina and a 1Tb m.2 drive to Windows 10 Pro.

It's been a long time since I did any kind of modifications to PCs (last full build was 2008), so I'm curious and excited to see how this turns out.
