I want to have two separate Windows installations on two separate disks on my PC (with Secure Boot enabled). The first installation succeeds and works fine, but when I try to install another Windows on a second disk, the very first reboot during installation does not work (it boots from the wrong partition/disk).
Trying to boot to the correct partition/disk manually fails, as BIOS/UEFI does not show the second disk as a boot option.
How can I install Windows separately on two disks, so that I can boot from one or the other in BIOS/UEFI boot menu?
