Windows 7: Is my WIn7 UEFI, or not? I have conflicting results.

Is my WIn7 UEFI, or not? I have conflicting results.

My Windows 7 is installed on an Asus M5A97 UEFI board with latest BIOS from 10/12. Windows 7 was cleanly installed this week (after a disk failure BTW). I could tell, when entering BIOS and selecting to boot from CD, that the DVD was listed as a UEFI boot disc. So, I assumed that the installation would install itself as UEFI.... but is that what really happened?

I followed the instructions for using MSINFO32, looked for the line BIOS MODE... it was not listed at all. Weird. I ran the same MSINFO32 with admin privileges, same results.

What do you think?

BIOS Boot order displays a UEFI Windows Boot Loader. Drive C:\ consists of three system partitions on a GPT disk. However, based on the LACK of information from MSINFO32 I am not sure if Windows 7 is UEFI, or Legacy.

I am looking into this because I want to set up a dual boot with LinuxMint 15. I understand that If Windows is UEFI, then the LInux install MUST be UEFI as well...

Thanks for your input.

Robert

Can you post a screen shot of Disk management?

The screenshot below is
(A) Setup is Windows 8 in UEFI mode, than dual booted with Windows 7.

Do you have two Windows 7 installs? The connectors for disks should be swapped so the primary Windows 7 in in the Disk 0 position.

Why switch hard drive cables?

Okay... bare with me.

No.... I have only one Windows 7 installation. Why is it recommended to switch cables so that the OS disk is Hard Disk 0?

I know... what a dumb question. Will disk position have anything do do with my Linux partition not booting up?

I'm learning.

Thanks

I can't remember why the OS should be Disk 0, but I've asked for help with it and for Linux, which I don't use. This in itself shouldn't keep Mint from booting but two of the three partitions you labeled as Mint say they are RAW which should be empty, unallocated space yet you have a drive letter on them.

Your F partition says HOME-WINDOWS7 plus you labeled C as Windows 7 too hinting you have Windows 7 on two partitions.

This is our thread about disk 0, linking to the article with the actual explanation.

As for linux not booting, UEFI support in Linux isn't as smooth as it should be. You can find plenty of people having similar issues. But it's usually solved with some terminal wizardry.
This post should help you.
The stuff written on the same line after the # is a comment to explain what he is doing, it's not code.
Mint is an Ubuntu restyle so do the Ubuntu instructions.

Also this thread contains info about a tool that does it automatically if you can get it after install.

Britton30.. a reply

I learned the Linux trick of installing the OS to one partition, keeping documents on another. I labeled my Windows documents folder Home-Wimndows so I could tell, at a glance, which Home folder I was l looking at, Windows, or Linux.

C is your Windows 7 partition currently booted as signified by Boot flag in the screenshot.

If you're unsure whether F which you've (mis?)labeled Windows 7 contains an old OS I'd browse into it from C to see if it has a Windows and Users folder. If so then I'd move the data off to correctly delete the partition for an unwanted OS, then repartition in Disk Mgmt and move the data back.

If you need to keep the current HD as DISK0 then I would have Logical partitions which cannot accept the System boot files, or risk having the boot files derailed to DISK0 during future Repairs or Reinstalls. This is why it is best to have the OS on Disk0, with it or its boot partition in the first partition.
