EFI BIOS or not?

I see mention of EFI BIOS around here, and the instructions for Clean Reinstall - Factory OEM Windows 7 addresses it as well. So how do I find out whether my machine has it or not?

Easy way of knowing. Is your BIOS mouse driven ? Can you use the mouse to click on the options ? If yes then its a UEFI

Looking at the Dell site documentation and downloads (BIOS upgrades) it appears this is a standard BIOS and not a UEFI BIOS. The Dell documentation all has a 2009 date.

BTW, you should remove the Service Tag number from your System Specs list. Dell considers this personal data that should not be released to the public. On the Dell forums, the service tag on a post is forbidden.

Yes, it is mouse driven.

I guess I'll have to dig a little deeper to make sure what my particular system is.

Thanks to both of you for your help. :)

Not sure what you're looking at, but my service tag is not showing, and I just checked to make sure.




edit: There is an EFI folder in C:\WINDOWS\Boot, so that tells me what I need to know.

All 64 bit versions of Windows 7 have an EFI folder in Boot. It is not an indicator that you have an EFI (UEFI) system.

Having mouse control in the BIOS settings is a clear sign the system is UEFI, but please remember folks: you can have a UEFI system without a Graphical User Interface and mouse control. The GUI is a manufacturer option, as are many other features of a UEFI BIOS.

What you have listed as the motherboard model number looks like a service tag number and the reason I referenced that.
