I've used a few different mainboards (Asus,  Gigabyte) and I've never
used Windows to update the BIOS.

Most BIOSes allow updating from 1) a thumb drive with DOS (FreeDOS)
installed and the BIOS image present or 2) just a BIOS image on a thumb
drive with a FAT32 file system.  I always use the second option.

You should be able to get the mainboard's manual as a PDF on-line and
then take a look at the BIOS description.  It should clearly describe
all supported options for updating the BIOS.
