Hi, after some troubles I finally installed Win 8 on my GPT partition. In BIOS Setup I've checked UEFI in Boot List Option and in the Boot Sequence I can see item "Windows Boot Manager". So, It seems good.

However, after the installation, not a single boot attempt was successful. When I use F12 to see boot options, I can choose "Windows Boot Manager" from the list. After that, a blank screen appears and nothing more. When I use keyboard arrows up/down. List of boot menu appears again as I browse items.

BIOS version is the latest one (A09).

I've already tried to downgrade BIOS. Versions A03, A07 and A08. No result.

Although, I've installed Ubuntu to another partition. Now I can see two items in the boot menu "Windows Boot Manager" and "ubuntu". Still the same behavior.

IMHO, the problem must be with BIOS.

Any ideas?
