Samsung 960 evo M.2 SSD problems with Asus Maximus VIII Ranger mobo

[teemu.luukkala]

So I'm running out of ideas now and would appreciate a little help.

I recently updated my ssd to this Samsung 960 evo M.2 and hoped to install w10 to it. So I installed M.2 to mobo, unplugged all other hard drives and changed BIOS settings like as many threads and videos pointed out. Here was the first problem: in my BIOS there is not a option in Advanced/Onboard Devices Configuration/PCIEx8_4 and M.2 Configuration. I updated my BIOS to the most recent version but still nothing. So I just changed CSM disabled, Fast Boot disabled etc. and booted from USB selected my M.2 for installation and waited. All good until system reboots. I unplugged USB but when system tries to boot from M.2 it just kicks me to BIOS. If my M.2 is shown as a bootable device in BIOS it hasn't changed to "Windows Startup Manager" as it should.

Then another problem. I booted my system from old SSD and tried to update M.2 drivers and installed Samsung Magician software. Magician doesn't recognize my M.2. Windows and BIOS do. Why?
Also I checked M.2 folders from Windows and found there those Windows install files but still it just can't run the installation to the end.

Any ideas?

Specs:
Asus Maximus VIII Ranger BIOS ver. 3703
i7-6700K
Corsair Venegance 4x4GB 2400Mhz
MSI GTX1070

Which Windows ?? W7 doeasn't have drivers for M.2 SSDs, you'd have to inject v2.2 drivers from Samsung site. v2.3 doesn't work for W7.

You have disabled CSM which is your problem. Disabling CSM also disables the ability to boot using UEFI and UEFI is required to boot from newer devices such as M.2 drives

Set CSM to either auto (which should detect your device and automatically configure the correct setting)
or
Manual, (which will give you 4 additional boot settings which you can configure for your device) if you set it to manual, make the first option legacy first, which will still allow you to boot from CD drives etc. I think options are like legacy then legacy & UEFI... you will see what I'm talking about once you select the manual option. Manual also adds optiosn for network booting etc, but anyway the first option is the most important and should and should allow you to boot.

Let us know.
