Trying to move Windows 10 onto a new Crucial SSD, and when selecting the target drive, I'm prompted with an error message saying there is not enough unallocated space on the target drive. I believe I have everything set up correctly, and here is a picture of all my drives showing they're healthy and have plenty of space. (https://i.imgur.com/CVfAgnK.png)

Truly don't know what to do, thank you for the help
 
Solution
Delete partition D: before cloning.
Partition D: is using all the available space on the drive. There is no unallocated space left.

Also delete partition B: . That one is not needed and can mess things up.

Disconnect the 1TB Drive 1.
Delete ALL partitions on the new SSD.

I've not used Acronis for this, but...
These steps, exactly.

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 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 as necessary.
Delete the original boot partitions, here:

Hey, thank you for replying. So from my understanding, delete the D: drive from disk management?

Thanks, after deleting the SSD from disk management and going through with the system clone, Windows "cut" my drive in two (https://i.imgur.com/StzMw9c.png). Not sure what went wrong!

Thanks for all the help. Have the old drive copied to the new drive and it's got all of its storage, but now MSI won't let me into BIOS to change the boot order :(
