I recently installed debian-7.8.0-i386-DVD-1.iso on a VirtualBox. It "live booted" just fine and then I followed the install instructions. As far as I can tell it works. ??? I dont know. here is the issue. When I tried to instal from the Add/remove software in the applications. I get a notice to load 'Debian GNU/Linux 7.8.0_Wheezy_- Official i386 DVD Binary-1' in the dvd tray, after it starts to load/install. so what is really going on there? why do I need to use this? how do I get around it. I appreciate the input. Keep in mind I have know idea about how Linux works. First time user.
