I have the need to run Debian on my MacBook and have been told that the best way to do this would be through VirtualBox. I have downloaded and installed VirtualBox. Now.. I have no idea of what to do - I'm not too experienced when it comes to installing operating systems beyond OS X and Windows. When looking at the Debian website, there are several ways to download Debian and several kinds of images (alpha,amd64,hppa,i386,ia64,mips,mipsel,powerpc,sparc). I have no idea which of these I should download and how to get it working properly with VirtualBox. I'm running 10.5.5. Also, if this matters, I'm installing Debian to create a repository for Cydia.. I'm not sure if that alters how I need to install it.
