Hello, can anyone kindly help me I am trying to install my M.2 970 NVME on maximus x hero motherboard with windows 10 pro to boot on this.

I want to install it in UEFI mode not windows mode as I heard that is better way.

I am all new to this and only know for sure that i should set some settings like enable m.2 enable PCIE X4 as opposed to x2

don't understand the settings that will ensure it installs windows as uefi mode and do i need to format the the drive first to GPT before hand ?? I am confused on this too.

You see in boot section where it says different boot modes one of them says on default boot uefi and legacy

The other 3 below i think say boot legacy

Which ones do I change?

I dont understand all the guides i am reading they seem to conflict even where I would have thought they shouldn't for e.g. where the apparent desired end result is the same.

So do I need to format drive in windows first on my other PC ?
Do i need to make changes in bios other than the 2 i am aware of ?
How can I be 100% sure it is in UEFI mode?

Thanks for your time hope i don't take up much of it.

Again - boot entry "Windows Boot Manager" equals UEFI.
On system, that boots into legacy mode, you will not see "Windows Boot Manager" boot entry.

The evo drive fits into the mainboard. Look at the manual, there are two locations to install the drive, just pick one and install the drive on to the board.
Put the windows install files on a usb device.
Boot the machine into the setup/bios and set the boot selection menu to boot first from the usb. Stick the windows install usb into a usb slot .
Reboot and the machine should offer to run from the install media. If there are options on an install device, always pick the device with (UEFI) or Windows boot manager in front of the device option.This applies any time you have boot options.

Hi thank you for reply.

I did install it before like this but it was not installed as UEFI.
is there any specific settings to get it so that my bios in running in UEFI MODE first?

And like I asked before will i need to format the drive before to do so?

Thx

You must boot from windows installation media in UEFI mode.
In boot device priority settings there has to be entry with [UEFI] and USB device name mentioned.
If you don't have such entry, this means your installation media is not prepared for UEFI mode.
Recreate it with appropriate settings. Use rufus.

So i have the USB setup as UEFI windows in bootmanager priority 1.
When I install off of this onto the NVME and thereafter go back into bios i don't see the NVME listed as UEFI before it like just like the OS drive had.
It just says m.2 Samsung 970 evo but no UEFI before it.....am I missing something here..?

MERGED QUESTION
Question from Apparent : "M.2 NVME OS drive wont show up as UEFI in boot menu after installing in UEFI mode"

Specs:

8700k
500GB 970 EVO NVME
X hero.(NVME installed bottom slot m.2_2)
1070 evga
750w evga supernova g2
H150i pro rgb


Hi people.

So i have the retail windows 10 USB (UEFI)

I set CSM disabled BEFORE installing
Set correctly m.2 to x4
mode
SATA mode is in AHCI mode then after that I
Installed OS onto 970 evo.

When I go into boot priority
My drive is listed as (windows boot manager m.2 970 evo ssd 500gb )
and M.2 970 EVO ssd 500gb below but NOT listed as (UEFI M.2 970 EVO SSD 500gb).

I noticed for the first boot attempt everytime i clear cmos for another reason it will boot loop 3 or 4 times.

Any help please give full detail about installation method with regard to this issue rather than telling me to apply the same setting i have already mentioned only to disappear when I ask for further help PLEASE! i will really appreciate it. Thank you very much.

Windows Boot Manager entry in boot priorities is UEFI boot.
Can you post screenshot from DIsk Management?
If there's EFI system partition on your 970 evo boot drive, this means OS is installed in UEFI.

Hello again,

No it doesn't say UEFI
That is what I am wondering.

Disk management reports yes 100mb EFI partition , NTFS C: properties say GPT partition

Nope. Wrong link.

Anyway - Windows Boot Manager - means UEFI;
EFI system partition means UEFI.

You can verify it also with msinfo32 (look for BIOS mode).

Sry for that^

Ok so basically it is a confusion then...
it doesnt need to have it as UEFI in boot order? Yes it has windows boot manager m.2
And bios mode UEFI

Ok I guess this confusion arose for me and could for others because i used to always have it listed as UEFI before even with the same install drive on other machine. (HERO 7)

Thank you so much for clarifying and all your help
