Solved Determining BIOS or UEFI from windows.

[diplo]

I'm wondering if there's a sure-fire way to determine whether the underlying hardware running Windows 7 is of the UEFI or BIOS variety. I could research my particular laptop / hardware but I would like a reliable way of determining this quickly within windows for whatever hardware I'm dealing with. I was looking at this which shows several ways which people think you can find out, but I've found that they give me conflicting results. Any suggestions?

Take a look here:
BIOS Mode - See if Windows Boot in UEFI or Legacy Mode

Nice link, Ray.

Looks good, thanks. I will just go by what setupact.log says

What does setupact.log say?

It says BIOS on my laptop ( HP Probook 4540s ). My desktop doesn't have a setupact.log in its panther folder ( intel DB75EN ). On the desktop MSINFO32 gives a BIOS version and says nothing about a UEFI so I'm assuming it's a BIOS.
