Why Arch was removed from boot options in bios (after bios upgrade)?

Recently I did a bios update.
I have dual boo: Arch + Windows 10

After bios update, Arch disappeared from bios.
I use systemd-boot.

Fixing it was quite easy (arch-chroot + bootctl install), but I wonder why windows bootloader worked after bios upgrade and Arch bootloader not.
Can I prevent this in the future?

Motherboard is MSI x570 Tomahawk.

The update probably removed the UEFI boot entry. You should be able to add it back. Here is a generic example, you will need to look at your UEFI for the specific method of doing this:

MSI boards are notorious for only booting $esp/EFI/bootx64.efi and windows will override that as it is the fallback path, you are unlikely to get around this as long as MSI refuses to implement NVRAM properly.
