Deleting Patitions

I inherited an older server.  It has an 80 GB hard disk that is partitioned into C and D.  I am running out of space on the C drive and want to remove the partition so that I have one large drive, but I do not want to format the machine.  Is this possible?  Also, I want to install a larger hard disk as a secondary but when I opened the drive, I noticed that there are two drives attached to a controller.  I am assuming that this was meant for a mirror that was never configured.  Can I remove the controller and install a second hard disk?  The server is running Windows 2003 server.

You can delete the D partition and use Diskpart (command line utility) to add D to C

Does this affect the boot.ini at all?
No, not at all.

Keep in mind. We are talking about deleting the non Windows D partition.
OK.. You can only repartition\expand a primary partition on a server using software like partition magic server or the likes. You can only extend\change partitions using diskpart on a server if they are a secondary\non MBR drive.

If you are sure that the mirror was not created and is not a HW mirror (reboot the server and make sure it's not configured through the raid controller,  you should see the option during the boot up process. If it was not configured then yeah, just remove the controller and install the second drive.
