Windows installed to E drive instead of C

​ I have a Dell Dimension 8300 with 1 gig RAM and had a hard drive failing. I just installed a new hard drive (Maxtor 200 gig) and that went ok and the whole 200 gig showed up in the BIOS, but when I installed windows xp to the new drive and it installed fine except that it assigned the partition as E instead of C. I have a zip drive in the system and seem to remember that when a previous hard drive failed and Dell (when it was still under warranty) came to install a new drive (the one that just failed) it installed Windows to E then too and the tech said it was due to the zip drive. ​

​ How can I change it to reassign to C instead of E? (I can't get on the internet on that computer yet due to that and I know it will create other problems if I leave it as E) (I'm using my laptop to write this and the Dimension is in the other room). ​

​ Do I have to uninstall windows and reinstall and if so how do I make sure it installs to C this time? If I don't have to uninstall and reinstall how can I reassign it to C? Windows created an E partition when it was installing. Is that permanent ? ​

​ Help :) ​

​ Thanks in advance! ​
