I am dual booting Windows 7 and Arch Linux (both 64bit), with GRUB2, using the 64-bit EFI version.
Everything is working fine now, but with one problem. I can set the boot priority in BIOS (or is it UEFI?) to have GRUB boot try and boot before Windows Boot Manager. Then I chainload Windows Boot Manager using GRUB. However, when I actually use Windows in this manner, upon shutting down and turning on again, or rebooting, Windows seems to set Windows Boot Manager first in the priority list again, with the result being I have to manually set GRUB again, or I can't boot into Linux.
My motherboard is an Asrock H61M/USB3, if that helps.
I want to know how to turn off this behaviour.
