OK, no problem.
This will need to be a SINGLE drive with enough free space. Not multiples.
Also, another small blank flash drive.
Given that, we do it with Macrium Reflect, and an Image...
- Download and install Macrium Reflect
- Run that, and create a Rescue CD or USB (you'll use this later). "Other Tasks"
- In the Macrium client, create an Image to some other drive. External USB HDD, maybe. Select all partitions. This results in a file of xxxx.mrimage
- When done, power OFF.
- Swap the 2 drives
- Boot up from the Rescue USB you created earlier.
- Recover, and tell it where the Image is that you created in step 3, and which drive to apply it to...the new m.2
- Go, and wait until it finishes.
- That's...
