This is determined by your firmware, and not by GRUB. In general, no, this
isn't possible. On some firmware, you can switch between BIOS and UEFI, but
this is done by a setting in the options menu and requires a reboot
typically.

Also, UEFI is required on all *new* PCs running Win 8. It is not a general
requirement.

Most hardware that can run XP probably can't run Windows 8.1 AFAIK.

Not fully true. You can switch from EFI to BIOS but exact function
depends on exact EFI vendor. GRUB currently knows only how to do it on
macs (see appleloader).

Quite the opposite. Most computers with enough power can run both.

In general please don't propagate misinformation.
