Partitioning my storage, won't let me change Drive Letter

So I just built a new computer and partitioned my SSD when installing Windows.

What I did was, I partitioned 15GB for installing Windows in and left the rest for other usage.

The mistake was, I made the Windows Drive as C:/ and now I can't start installations on anything that doesn't give me the option to choose what folder to extract to.

Now I'm trying to change the current C:/ system driver to a different name so not everything will go to it by default.

But the problem is, when I try to change it an error occurs and says "The parameter is incorrect".

How do I get myself out of this mess without having to install everything again? :(
