Apologies if this is off topic. Looking to triple boot Monterey-Fedora43-Win10Pro on a:
MacPro5,1
144.0.0.0.0 firmware w/ EnableGOP
RX580 GPU
(Drive 2) An NVMe drive in PCIe Slot 4. Monterey Install.
(Drive 0) An SSD in SATA slot 1. Currently blank, but intended as a Fedora install.
(Drive 1) An SSD in SATA slot 2. This is where I want to install Windows 10 Pro.
I am following the "Installing Windows in UEFI Mode" guide on the OCLP Wiki and the part I'm getting hung up on is the bit where you delete the existing partitions on your target drive and create new ones. Just to reiterate, I am trying to install Windows 10 Pro on its own SATA drive—not an NVMe drive.
The problem I am running in to is that when I hit the "New" button and it creates partitions, the setup utility only creates an MSR and Primary partition. There's no 100MB System/EFI partition on Drive 1 like there is in the screenshot included in the guide. When I check [DISKPART> list vol] I can see a volume with an EFI label but it doesn't have a letter attached to it, so my hunch is that it is maybe pointing to the EFI partition on Drive 2 (NVMe Monterey).
Anyway, I guess what I am asking is if I'm overthinking it or if there's something I'm doing wrong. I know that I have to be careful if I don't want Windows 10 messing up my MP5,1's firmware, but I can't seem to figure out how I would remove the Windows option from the Stock Bootpicker if I'm not installing Windows 10 on to a drive with an EFI partition. Or maybe I'm not even supposed to be doing it like this and I should just try to find a guide for installing the Legacy BIOS version of Windows 10?
Thanks in advance for any help you can give. This forum has honestly been such a huge resource as I have gone through the process of refurbishing this old 5,1 and I am looking forward to keeping it around as a tinkering machine for years to come.
