That’s not a thing it can do in grub. It could do it with UEFI entries, but these days windows is not the biggest culprit of that. I had it happen on a BIOS update, where it simply nuked all stored entries, and the windows one is always checked as part of the standard.
Yeah, I was gonna say I dual boot and I can’t recall the last time that Windows nuked my UEFI bootloader.
But back when Windows still did BIOS boot, it was like every major release without fail.
edit: Rewreading your post it sounds like you meant updating the BIOS as a whole and not BIOS boot, so that’s my bad. Yeah, I definitely haven’t seen your circumstance, I had that happen consistently before Microsoft embraced the UEFI style booting
