I know these suggestions aren't optimum (someone else may have a much better suggestion), but it would be a way to accomplish your goal (choose one of these four options):
1. Borrow your friend's DVD drive
2. Network your computer to your friend's and share the DVD drive by setting up an ftp server on your friends system. Then get a debian network boot floppy for your system.
3. If you have broadband internet access, just download the debian-installer CD (
http://www.debian.org/devel/debian-installer) and install the system via an ftp mirror (note that this will install Debian testing...if you're looking for Debian stable, you'll need to do a search for woody installers).
4. If your friend has broadband, download and burn the installer CDs.
The reason why I can't just say copy this and that from the dvd is because during the debian install process, it expects to find packages in a certain order. I don't know what that order is, so i can't say put just these packages on the first cd, etc. If you just put packages at random on each cd, you're going to be going through a lot of CD swapping during install, and that would just be a pain in the neck (you would have to try each of the cd's each time it goes to install a new package...unless you wrote down exactly what package you put on each cd).
Hope some of this helps.
