So I have installed a M2 SSD on my motherboard and, with MiniTool, I migrated the OS from my old SATA SSD to the new M2.
The problem is that now I have two windows installations, one on C: (the old SATA ssd) and one on G: (the new m2)
Since the M2 drive is faster I want to boot my pc with that installation, I tried doing that from my motherboard BIOS but nothing has changed.
Tbh I want to get rid of the old installation and have windows only on the new drive... How can I do it?

"one on C: (the old SATA ssd) and one on G: (the new m2)"

You missed a critical step - Disconnecting the old drive after the clone and powering up for the first time.
You are still booting from the old drive.

Redo the clone operation, exactly like this:

-----------------------------
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)
If you are cloning from a SATA drive to PCIe/NVMe, install the relevant driver for this new NVMe/PCIe drive.
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

If you are going from a smaller drive to a larger, by default, the target partition size will be the same as the Source. You probably don't want that
You can manipulate the size of the partitions on the target (larger)drive
Click on "Cloned Partition Properties", and you can specifiy the resulting partition size, to even include the whole thing

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 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.

There's isn't a more simple solution? I just can't disconnect my hard drives except maybe for the m2 cause it's mounted on the motherboard.
The drives are mounted in like a case slot, I would have to unplug many cables and unscrew many case parts :/
Also yes the destination SSD is twice larger than the old SSD.

At the end of the clone process, disconnecting all other dries is not optional.

The system NEEDS to power up for the first time with only the new drive.

You can try it now, without redoing the clone. It might work.
But the other drives MUST be disconnected.

Currently, your clone operation did not work. There is no easy clicky way out of this.

Got it, I'll try disconnecting the sata cables from the motherboard it should be easier...
If it doesn't work I'll do the way you told me.
Thank you for the instructions :)

Hey hello again.
I did the step you suggested me and it worked! Windows is on my M2 SSD.
Thanks again, just one more question:
I have plugged back the old SATA SSD and deleted the old win10 installation so now it's empty, I still want to use it for storage.
For some reason tho windows file explorer doesn't recognize it, but other softwares like AOMEI partition assistant or even windows disk manager do.

How did you "deleted the old win10 installation" ?

Does it appear in Disk Management?
Screencap, please.

No I mean since windows is now on the new SSD, I deleted the old windows files from the other SSD, I basically formatted the whole disk. (the program I used to transfer the OS just copied and pasted the files from a disk to the other, it didn't delete them tho)... Now I'm 100% sure that it will boot from the M2 SSD since there's no windows on the old SATA SSD.
To format it I used the AOMEI software, I just pressed format disk/partition.
