I have two SSDs: one contains SteamOS and the other contains Windows 11. I'd like the computer to show a boot menu at startup so I can choose which operating system to launch, rather than repeatedly pressing F11 to select a drive. What is the best way to configure this?

Install or use a bootloader such as GRUB or Limine, then make that bootloader the first entry in your UEFI boot order. It should detect the Windows Boot Manager and display it as an option alongside SteamOS.
On some Linux installations, Windows detection requires enabling OS prober before rebuilding the GRUB menu. You can leave it enabled, or manually add the Windows Boot Manager entry and then disable OS prober afterward if you prefer a more locked-down setup.
If SteamOS is already using GRUB, boot into SteamOS and regenerate its configuration with `sudo update-grub`. After rebooting, GRUB should provide a menu with SteamOS and Windows, assuming the Windows drive is detected.
