Problems installing Windows 7 in M.2 Samsung SSD

Hello, i'm having some issues.

I'm trying to install Windows 7 on the M.2 Samsung SSD / ROG Impact VII motherboard.
And I get all the time " It's not possible to install windows in the Disk 0 Partition 1 (Show details). "

I've already checked in the BIOS that the M.2 slot is activated and i've also tried the (diskpart, select disk 0, clean) guides


I've already tried this and nothing:

What else can I do to fix this?

Those links don't go anywhere.

Do you have a UEFI BIOS? If so then what are the BIOS settings for UEFI, CSM, Legacy BIOS, Secure Boot and BIOS Boot order priority? Pictures will help if you're confused. UEFI installs also require special steps if using a Flash stick installer and booting the DVD or stick as a UEFI device to delete all partitions during install.

If no UEFI then work through the steps to Troubleshoot Windows 7 Installation Failures - Windows 7 Help Forums.

This is a brand new computer, the disk is clean and it's an M.2 SSD.

I checked under Boot menu OS Type has selected (Windows UEFI Mode) the other option is (Other OS).
Under CSM is already Enabled and the Boot Device Control is (UEFI and Legacy OPROM) the remaining selected option below are all (Legacy OPROM first).

The boot order is
1. USB
2. M.2 SSD DISK

OK so we'll guess that you're installing from flash stick since you don't bother mentioning this. And of course we dont' know anything you've tried since your links went nowhere.

If USB then the stick needs to be formatted using only Option One of UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.

Plug in the stick and reboot, tap the key for boot menu, does an UEFI flash stick device appear? Choose it and then delete any partitions during the install, with only the SSD plugged in. This should allow formatting the disk as a GPT device needed for UEFI install.

If these fail and you're sure you formatted the stick exactly as pictured in tutorial, then we'll need to see the exact BIOS settings you make scattershot reference to, all expanded with every choice shown. Use a phone camera, well lighted, attach files using paper clip in reply box.
