So I have updated the latest bios on my motherboard ECS H61H2M2, which has enabled Support for Win8 UEFI boot. But the problem is, when I set the operating system as Windows 8. My computer is unable to boot after that. I don't get any display and neither I can see any system activity after starting it up and also del key to get into bios setup doesn't work either.
The only way then to recover is clearing the CMOS (via jumper on motherboard).
I have a UEFI image of windows 8 ready on my USB pendrive, which boots up the windows installation fine in legacy operating system mode, so I know pendrive image is not the culprit. I'm attaching the BIOS settings which are automatically set when i select the operating system to Windows 8.
Can anybody advise me, what I may be doing wrong or what I can do to fix it ?
