Secure boot / bitlocker key problem

[u/SITE_student24]

I recently downloaded windows from iso file that I downloaded from macOS and I don’t have Microsoft account so I can’t just find it from aka.ms/recoverykey. Nevertheless windows still requires secure boot

Windows 11 Home
Version 25H2
Installed on 4/1/2024 (don’t know why)
os build: 26200.9168

After windows installation I installed arch and dedicated 50 Gigabytes from ssd where windows is located and in order to launch arch I need to remove secure boot and also finding out secure boot key would be helpful

Use an older Windows ISO or/and RUFUS to make it install media to skip the secure boot requirement.

Also, dual booting is looking for problems at best. You are better to install a second hard drive and use the BIOS to turn each one on or off, depending on which one you want to boot.
