Hello everyone,

Complete and utter noob to computer building here. Today I received my new Wd blue SN550 1TB internal NVMe SSD and as a noob would do I failed to format before attempting to use Macrium Reflect and try to transfer everything from my terrible Seagate SSHD. While it was in the process it stated on screen there was no drive to copy the files to. I then realized my error and cancelled the process. I then went to format the drive and noticed it was only showing the drive at 465 GB total. I then did a quick search and learned I needed to partition the drive to get the full 1tb. I then went to Disk Management and noticed it already had a recovery partition and EFI system partition on the drive. I then decided I wanted to deleted everything from the drive to start fresh. I did more research how to delete these partitions and went to diskpart to delete them. I deleted them and went back to see if I could format and start over... However now it won't show up on "this PC" and when I go to disk management it sees it there but there is no option to change driver letter or format. It only says disk 1 and unallocated. In diskpart when I type "list volume" it only shows my primary drive and the SSD doesn't come up. Sorry for the long probably very confusing explanation. I will do my best to answer any questions as I really don't know what to do from here. I appreciate any help/advice in advance. Thanks.

And for the migration operation...

-----------------------------
Specific steps for a successful clone operation:
-----------------------------
Verify the actual used space on the current drive is significantly below the size of the new SSD
Download and install Macrium Reflect (or Samsung Data Migration, if a Samsung SSD)
Power off
Disconnect ALL drives except the current C and the new SSD
Power up
Run the Macrium Reflect (or Samsung Data Migration)
Select ALL the partitions on the existing C drive
Click the 'Clone' button
Wait until it is done
When it finishes, power off
Disconnect ALL drives except for the new SSD
This is to allow the system to try to boot from ONLY the SSD
Swap the SATA cables...

Please show us a screencap of the Disk Management window.
I actually believe I figured it out... I didn't realize the "new simple volume" option was "clickable". I should be good to go thanks so much for the quick reply... Just a noob doing noob things... I actually think this thread can be deleted... Sorry to inconvenience anyone reading it...

Swap the SATA cables around so that the new drive is connected to the same SATA port as the old drive
Power up, and verify the BIOS boot order
If good, continue the power up

It should boot from the new drive, just like the old drive.
Maybe reboot a time or two, just to make sure.

If it works, and it should, all is good.

Later, reconnect the old drive and wipe all partitions on it.
This will probably require the commandline diskpart function, and the clean command.

Ask questions if anything is unclear.
