mmm
Got Clover Configurator and did these updates. But I can't see any countdown when booting. It goes into clover bootloader and waits for input. Before it was the same, it wouldn't boot to any OS unless I select it.
What is your timeout integer? You cannot use 0.

It was 3, changed it to 30, made no difference. I assume 0 means wait for input?
Do you really need 30 seconds to select an icon? Try 5 seconds.

Hi, I need help installing Windows in a separate drive. I read the first post but I haven't a full understanding.

I've installed Macos (Mojave) in one drive. Running succesfully.

Then, I built a bootable USB installer with windows 10 with dd terminal command. It works.

When I run the USB installer, a warning of missing media controller is shown.

Any help appreciated.
Hi man, I have the same issue, Did you resolve?

Try using one of the USB ports next to the PS/2 port for KB and Mouse. These 2 are usually always active with drivers included in the firmware.

I had windows already installed in drive 1.
I unplugged and installed Mojave on drive 2.
then followed the suggestions fom @Going Bald to fix my boot partitions and clover.
Although, I can't still make it work to boot automatically into any OS. I need to manually select the OS on the clover menu to boot in.

I have read through a lot of pages and didn't really see the answer to this question.

Can I have 2 drives:
1. MacOS Catalina (already installed and working) with clover bootloader.
2. Windows 10

Just install Windows 10 by selecting the bios bootloader, select the win 10 usb, install to clean 2nd drive.

Then just use the bios bootloader to select the windows drive when I want it and not even use clover to boot windows?

Using Clover Configurator you can change the default boot volume under "Boot" subsection. see where it says MacOSX in my screenshot change that field to what boot volume you want or "lastbootedvolume and it will boot into whatever you had opened last, also another option is to use your BIOS to select the boot volume if you want windows, IMO it is easier to use the clover boot menu.

Disconnect the macOS drive first before doing this.
