Question What did i do wrong? Cloning windows

[BillWiTheScienceFi]

I was trying to clone windows onto my new pcie m.2 SSD and i went through the instructions and used macrium reflect, once it was all done copying its now telling me I have 2 of the same storages but [A:] should be the 2TB new ssd, so why is it saying 465gb[C: is my current one w/windows]? Did i do something wrong?

Going into disk management its showing the rest of the drive as unallocated, I alocated it before all this now if i try it, it wants a whole seperate drive letter from what i just copied windows to...

When you clone a drive with Macrium a little pop up box should appear asking you if you want to expand the disk partitions to fill all the space on the larger drive. Maybe you missed that pop up or selected the wrong option. Try again and look for the pop up box.

You didn't do cloning properly.
Cloning means - making identical copy.
Clone source drive has 3 partitions.
Clone result drive has only a single partition. Result is not bootable. EFI system partition makes it bootable.

Don't ever use drive letters A: and B: . Those are reserved for removable floppy drives. Nobody uses those.

Redo cloning properly. Clone all partitions.
After cloning is cone, extend OS partition on target drive. This can be done in Disk Management.
When you boot from cloned drive for first time, clone source drive has to be physically disconnected.
This step is not optional. If you skip it, drive letters on cloned drive get messed up and you have to redo cloning.
