You should be able to take an image of the SSD and transfer it to the new HDD no problem. Once you have it on the new drive you can open the windows disk management tools and enlarge the partition to fill the entire drive if that is what you want to do.
In order to take the image and copy it over you could either use the built in windows imaging tools (control panel->backup and restore->create system image), or my personal imaging choice is Macrium Reflect Free
. Either method will involve you creating a system image and creating a 'repair disc'. You then swap out the drive, put the new HDD in, boot from the repair disc and follow the instructions to place the image on the newly installed HDD. It shouldn't even take too long.
