Priorité de démarrage SSD M2

Hello,

I'm reaching out to you because I'm having a small issue with the startup of my computer. Nothing too serious; I'm actually writing to you from it.
Let me explain everything I've done so far.

I purchased a 1TB T-FORCE Cardea II M2 SSD. I already had a basic 120GB SSD in my computer, on which the system was installed.
After installing the SSD on the motherboard (MSI Z370 a pro), I checked my Disk Management on Windows to see if my SSD was recognized. HURRAY it's there!

I then started a migration of my OS using MiniTool ShadowMaker.
At that moment, everything was going well; all the content from my SSD was available on the new one, so I proceeded to format the first.

But then a problem arose, my computer doesn't restart directly and shows me an error message. I restarted and pressed F11 to boot manually. I selected my T Force SSD and Windows started perfectly (and super fast).

After some research, I dived into my BIOS to change the boot priority and put my new SSD at the top of the list. But there’s a problem; it’s not in the list.

So here I am, asking for your help to know exactly what to do because I'm starting to go around in circles. I would really like to be able to turn on my computer without having to do unnecessary manipulations.

I remain at your disposal to provide you with any additional information you may need.

Thank you in advance!
