M2 Drive not recognised but Windows does


I have an older NUC 5 , I installed a M2 drive, booted from USB installed widows 10 onto the M2. But try to boot into the M2 after install does not work.

I then go back and boot from the USB windows installer and its there are a drive, but the bios cannot see it.


Any suggestions?

What NUC 5?  What bios version?

Legacy or UEFI install?

[Maybe Windows 12 will be better]


Its a NUC5i5RYH, tried both Legacy and UEFI installed, just finished with Ubuntu same thing, installs and sees the drive but Bios does not see it

For M.2 drives, you *must* use UEFI boot - even for Linux. If heading towards a dual boot configuration, install Windows before Linux. When you get to the screen in the Windows installer where you select the System partition, you *must* delete all existing partitions on the system drive and then select to install Windows to the unused/unallocated space entry for this drive (which should encompass all of the drive at this point if you have deleted all existing partitions). This process is necessary to ensure that any older, legacy partition table is properly replaced with a new UEFI partition table. It also lets the installer choose the optimal partition layout for the drive.

Hope this helps,



Thanks, i have done everything i need to in order to get it to work (Including clean install/Partitions etc.) , just seems strange that the BIOS can't see it, the only thing is that the drive is a NVMe drive not a SATA so have ordered a SATA M.2 to see if it likes that better,

In BIOS Setup, if you go to the Boot Setting page, do you see an entry for the drive in the UEFI Boot box on the left (and do you have the UEFI box enabled (checkmarked))? If not, but the drive is appearing in the Legacy Boot box on the right - then the drive does not have a UEFI partition table. This can happen if using older Windows installation media. In this case, I suggest that you rebuild your installation media using the Microsoft Windows 10 Installation Media Creation tool (available here: Similarly, for Windows 11, rebuild your installation media using the Microsoft Windows 11 Installation Media Creation tool (available here:

This can also happen if you are not booting the installation media using UEFI. When selecting the USB flash drive from which to boot the Windows installer, remember to select the entry that is preceded by 'UEFI'.

Hope this helps,



In the BIOS the drive does not show up full stop be it UEFI or Legacy.


To be clear i used the Windows 10 tool, and built it, booted the USB via both methods UEFI and Legacy, I wiped the drove clean removed all partitions. 

The drive has a EFI table built, and to double check it putting it in my other PC it shows correctly.


The drive can only be seen when booted into live Linux or when installing windows, the BIOS never sees it, i'll put it down to the NUC being a **bleep** and once my other drive is delivered i guess that will answer the question that it just does not like the Nvme drives i have of which i have 2
