So 1281 is used for single core Xeons and up to 6 core Xeons?
EDIT - Ah yes it worked, it now shows 2x quad core xeons.

99% your RX580 is flashed. Please go TechPowerUp, download a ROM that's for your card, and flash it.

Please remove everything, and re-do it by following post #1314
I'm unable to boot into windows without the boot picker and startup disk doesn't work, I'm trying to flash my rom.
I thought it was Uefi but I may be wrong. There is 3 including the windows. one with Mojave and one with OC and Catalina.
I did get my 580 flashed with the correct rom. and the boot picker does not show the windows drive.
If the bootpicker does not show only your Windows drive then it is not UEFI Windows or the EFI folder for your Windows is not the first partition on that drive.
How do I reinstall windows in UEFI? Do I use bootcamp and is there a special way I should make the installer ie. using media creation tool to a dvd or windows usb installer drive?
What I did, in my humble knowledge of anything Windows, was to reuse an old 500GB internal hard drive I had removed from the Mac and install only Windows on it. No partition nightmare, no risk of altering my Mac OSes, etc. And when I need to use Windows (very rarely, let's be honest), I just remove all the internal drives and put the Windows drive in. When the Mac tries to boot and can't find its usual startup disk, it just goes for what's available - therefore Windows.
Today I tried to drop Min Kernel to 16.0.0 (Sierra) and I was able to boot into the Sierra partition. Interesting!
Was also able to boot into the Recovery partitions by unplugging the second monitor and only keeping one on the main port (the one Mac OS calls "1" when in System Preferences / Monitor).

Use this guide, this for Windows and this manual. The guide missed sudo. Use this command:
Code:
sudo VBoxManage internalcommands createrawvmdk -filename "</path/to/file>.vmdk" -rawdisk /dev/disk#/dev/disk# is the disk number where you will be installing Windows revealed by diskutil list. First, make sure the drive is connected and unmounted:
Code:
diskutil unmountDisk disk#Make sure Vbox machine is in UEFI mode:
Otherwise you will be installing it in MBR mode. Next, start virtualbox with sudo and always use sudo to start virtualbox:
Code:
sudo VirtualBoxsudo virtualbox from Terminal (always start virtualbox with sudo when accessing raw drive), select the desired VM, click Settings, click Storage, click Add Hard Disk button, select Choose existing drive, and then select the VMDK file you just created. Attach Windows.iso image downloaded from Microsoft.Start installing Windows from the Virtualbox, but during first reboot power down the virtual machine from the virtual box as soon as you see some text on the screen. Do not let it reboot completely from there. Continue installing Windows once you reboot the cMP through the OC where you will select the Windows option. Do not boot Windows without OC. Later you can replace bootX64.efi file in the Windows EFI folder with the OC bootX64.efi and point to bootmgfw.efi (you need to find the location of this file in the Windows EFI folder either in the debug log or with
devtree > devtree.txt, map -r > map.txt from UEFI shell). This step is not necessary with OC versions>=0.5.9, because OC automatically finds bootmgfw.efi and the entire folder /EFI/Boot can be safely deleted if Windows is the only boot loader on that drive.

He can't see the boot picker yet.
I suspect his card's GOP is broken. If I am correct, may be he can still boot Windows by pressing the number key during boot.
I believe he installed the "standard" package, with 10s time out.

Try press "2" after you hear the chime (around once per second, press a few times).
If the boot picker is there, you should boot into Recovery Partition.
If this work, then try 3, 4, 5 etc... you should able to boot into Windows to flash your RX580.

I have now fixed the gpu issue. It was flashed with a custom rom but I found the original and now I see boot picker.
Still a little confused, I have my OC EFI on my Catalina NVME drive. So id have to modify windows after installing?
After following this Carefully It doesn't show up in the boot picker, I have also burned an windows iso to a dvd, and was able to boot into the windows installer, then went through the process of installing windows but upon restarting after the installer says to restart, the hdd I installed windows to does not show up in the boot picker, but the dvd does. The dvd shows up as " EFI SECTOR"
You have to reboot but with vbox but immediately shut down the vbox not letting it completely reboot.
Thanks h9826790 and all contributors for the hard work that has made this possible. Much appreciated!
HW Accel working is great! No crashes so far, testing with AME2020 MC2019.12 DR16.2.
I am wondering, is it possible to have recovery mode with Radeon VII?
Bootscreen shows the three options: Mojave, Recovery, NV.
Mojave boots I get grey apple screen until just before desktop with quick dip to black and then login screen.
If I choose recovery I get apple loading for about a minute then just black screens.
Thanks again, this is awesome!
