Windows boot manager not recognising M.2 NVME SSD

[iec0]

Hi,

I have a ASUS MAximus VIII Extreme motherboard. I have installed win 8.1 in an samsung M.2 NVME ssd, However, the computer does not boot from the SSD. I have set the boot priority to the M.2 SSD first and then Windows Boot Manager. My BIOS version is 1202, which is almost the latest. The other 2 newer versions don't have anything to do with M.2 SSD.

Did you install windows with that ssd in that computer?

Try changing the boot priority to the Windows UEFI boot manager or changing your BIOS settings from UEFI to legacy, or reverse. Enabling or disabling CSM, compatibility support module or compatibililty mode may help too. The very first thing I'd do is make sure you have the most recent BIOS version installed.

Version 0907 added support for Samsung M.2 compatibility, so either that or any newer bios version should help if you have an older bios version.

ASUS Maximus-VIII-Extreme BIOS version 0907
1. Update Intel® ME version to 1168
2. Enhanced memory overclocking range to DDR4 3866(OC)
3. Improved compatibility with Samsung M.2 SSDs


If you had other drives attached to the system, or if the drive that used to have Windows installed on it is still attached, I'd disconnect all drives except the M.2 device and reinstall, as there may be a problem with an older boot partition.

Yes. I have installed win 8.1 and have set the boot priority to the ssd and then the boot priority is for WIndows boot manager. But it never boots from the SSD. I have to go to the UEFI and from there I have to select Windows boot manager under overrirde boot priority to get into windows. If I select the ssd from the Override boot priority I the screen just flickers and I am back on the same page.

Did you have other drives attached to the system when you installed windows to the SSD?

Do you have BIOS version 1402 installed?:

Have you tried disconnecting all other drives, disconnecting power from the system, removing the cmos battery for five minutes, reinserting the cmos battery, returning power to the system, booting into the bios and setting to optimal defaults?

Does check those newer bios versions may add nvme support and nvme is a newer controller for m.2 drives and nvme also only supports uefi boots and not legacy so gpt partion only folks
