Windows 10: I want to move Windows 10 from an SSD to an M.2 - What is the best way?

I have windows 10 on a 240GB SSD and it is starting to fill and is a slow boot. I have cleared items that were booting with windows and keeping it to a minimum. With me upgrading my PC to multiple M.2 drives, I would like to move Windows to one of these drives versus the SSD that it is on now, for speed and for storage. What is the best way to do this?

M.2 SSD Drive With Windows 10 Listed as Disk 1 in Disk Management,

Hi, In my pc M.2 SSD with Windows 10 OS is listed as Disk 1 and not as Disk 0 in Disk Management. Also, the same drive is listed as Removable devices which is actually internal SSD.

Can anybody help me resolve this, please?

 

M.2 SSD not being able to boot from it, windows doesn't recognise.

Ok, this is what happened after all the comments and suggestions, @dude: Thanx for the video, my mb had non e of those settings, it had the raid/option memory gene or achi. Can only choose one or the other. @Saltgrass, my settings did point out auto and enabled the pcie x4, gen 3. I did an bios flash as suggested, because my bios was not the latest version, after a reformat the m.2 was picked up, still cant install OS onto it as it states legacy not found, removed my dvd rom from the sata port to another, and the drive was found and installed. Only issue now is that it's still not my OS drive but it at least now works and is installed, but on the Intel rst drive the obtain memory gene option to enable is greyed out, and shows as disabled. However the program lists the M.2 and it is working 100%,. I installed overwhatch onto it, it performs perfectly. But will update the intel driver tonight and see if that makes any difference. Seems the bios flash enabled the settings listed by @dude that was not present pre-flash.

So the m.2 drive works. I can game off it and install omnto it. Can not install windows on it, gene memmory is enabled, pcie x4 is on and on auto detect, Motherbaord lists all the drives connected, motherboard ahs been updated to latest bios. After flash new settings became available, m.2 is now on memmory gene enabled not achi, windows os is enabled and fast boost is enabled, intel rst is installed and lists all the ssds and the m.2, however the m.2 on memmory gene is dissabled and the option to enable is greyed out. Will update the driver as Essenbe suggested of the m.2 and see if anything changes. Thank you all for the help, I can now atleast use my m.2

 

transfering windows 10 from sata ssd to m.2 ssd

Yes, here are your options:

Option 1: Cloning:

How to Clone or Move Your Windows 10 Installation to a Larger Hard Disk or SSD

Option 2: download, create a bootable copy, then perform a clean install then reinstall your apps. There is no deactivation involved.

Step 1: How
to download official Windows 10 ISO files

Step 2: Install the new SSD

Step 3:

• How to: Perform a clean install of Windows 10

When you upgraded from a previous version of Windows or receive a new computer preinstalled with Windows 10, what happened is the hardware (your PC) will get a digital entitlement, where a unique signature of the computer will be stored on Microsoft
Activation Servers. The Windows 7 or Windows 8 genuine license you were previously running will be exchanged for a diagnostics key.

Anytime you need to reinstall Windows 10 on that machine, just proceed to reinstall Windows 10. It will automatically reactivate.
You will prompted to enter a product key a couple times through the installation, click I don't have a key and Do this later.

There is no need to know or get a new key, but if you have issues with Digital Licensing or the Activation Troubleshooter, you can utilize an existing Windows 7 or Windows 8/8.1 product key
you already ownto reactivate if necessary. or use the reset function in Windows 10.
