So, I've got several debian install disks, but i'm attempting to install it on a qemu virtual machine, using curses as the graphical output. The issue i'm having is that curses doesn't do very well with graphical interfaces, and since the debian boot disks boot directly into a gui, all i get is a black screen on startup. Is there any way to install using a cli instead of a gui? Just hitting a few hotkeys and getting a cli would be ideal. 
How can i install Debian without using the install gui?
debian;system installation
