MY HD is currently labled as H. Long story but it is the only HD currently in the system. I have run into a problem trying to install Nvidia GPU drivers. I can unload them to H but when they try to install they want to install to C and it does not give me a chance to change the install to H. Is there a way to change my drive letter or a work around for the driver install. OS is currently Vista Business 32 bit. Thanks in advance
