Oh dear, this is going to be tough. I would suggest you put on hold whatever it is you intend to do on this Linux machine, get a book or download a guide (see
www.tldp.org for some good ones) and read up a little though. It's really hard to explain this in a single forum post, but in a nutshell:
- Linux doesn't understand drives letters. It only knows mount points and device files.
- A mount point is a directory where another filesystem can be "mounted" on. eg. if you have a directory called /foo and you mount your windows partition on it, the subdirs in the win partition will hang off /foo. eg /foo/windows, "/foo/Program Files", /foo/config.sys
- A device file is a special "file" that (usually) represent a particular hardware. eg /dev/hda /dev/mouse. Writing data to a device file is like writing directly to disk sectors (in the case of disk devices).
To all the Linux apologists: Repeat after me, "Linux is NOT ready for the desktop".
