So, I have two drives. #1 is a 1TB M.2 SSD, I’m currently dualbooting W10 and Linux Mint. (Please don’t hate, I use Windows only for work, cannot drop it. #2 is an older 250GB Sata SSD, it’s empty. I want to fresh install both OSs to #2 and use #1 as home for Linux.
Problem:
Drive #2 doesn’t show up as boot option in EFI (MSI Z690-A), only #1. When I boot into Windows setup from USB, I can start the installation, but it wants to reboot during the progress and I can’t choose #2 at all. So it boots into Linux, I see unfinished Windows on #2 but can not do anything about it.
I’m no beginner, but I’m clueless here. Any help?
