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.
