NEW SSD DRIVE NOT VISIBLE AND NOT BOOTING

[N-Victor]

Hi all. I purchased the Samsung 970 EVOplus NVME m.2 SSD for my laptop. I successfully installed it. At set up, I chose a format other than NTFS and allocated a drive letter S. It then showed up on my computer. I proceeded to clone my current hard disk using the samsung data migration tool. I then tried to change the boot sequence to boot from the SSD but this was not successful. I cannot see the SSD on "my computer." It shows up on device manager and samsung apps see it. Diskmanagement options are grayed out despite logging in as admin. Was hoping to at least reformat it to NTFS, or restore it to factory settings and restart the process afresh. 

Second problem is that I am unable to create a windows recovery USB as it says some files are missing. A successful clone and running from the SSD would be my best bet. Please help. Thank you in advance.

I've noted something: It says the disk is offline because it has a signature collision with another disk that is online. I believe this has to be as a result of the cloning. I do not wish to remove my previous disk, which I want to keep as a storage drive. How would I proceed here? Thank you in advance. Please note that I am not an expert in IT stuff. Interested, and love tech stuff but not quite there.

So, in the intervening time, I have come across this excellent article online on how to resolve the id conflict.:

I have followed the steps, rechecked the unique ID and its now different. However, I am waiting to restart the device. Hopefully this will bring the stated changes. Waiting though as I am creating a bootable USB windows disk due to problem 2 posted above,

I would have suggested removing the cloned "source" drive but these suggestions in the linked article will work. At the end of the day, however, you do not want to have 2 different bootable disks in the laptop at the same time.

Thank you Sir. The stated steps got me to have the SSD recognized, online and accessible. I now see it in the boot options. However, when I select it, I get a blue screen immediately. Error code: 0xC000000e. Running chkdsk as I type this on phone. 

The mistake I thought I'd made earlier (Non NTFS format) turns out was actually not one. I chose GPT instead of MBR, which I read is a good thing. I have disabled legacy support and secure boot.

Would be grateful for any advice that'll get me over the line :). Thank you in advance. Also reading quite a bit online about this stuff.

I always advise to remove the original drive when you have cloned to a new SSD. Otherwise issues as you have described are very common. FAT32 format will work for Windows 10, but not preferred. NTFS is faster and more secure.
