I have a brand new Gigabyte GA-h77-ds3h motherboard (it works fine).
My problem is, that I cannot install Windows 7 64bits in UEFI-GPT mode on it.
When I boot from the installation DVD, I have absolutely no option to use UEFI booting,
which is not the case if I boot any 64bits Linux install medium.
(For example, I use an Arch Linux system in UEFI boot mode on another hard drive).
What could be the problem?
