I am also a Linux admin, although I am adept enough with Google to
guess that these instructions might help:

https://www.windowscentral.com/how-disable-windows-10-fast-startup

Basically, with Fast Startup enabled, windows never really shuts down
but goes into hibernation, so next time you "power up" it is just
waking up.  So, you never get a chance to see the GRUB menu.

If fast startup isn't set, then you probably will need to boot off
rescue linux media and fix the boot order with `efibootmgr`.
