I appreciate that.

Awesome info here. Thank you.

I need to place /boot at the beginning of the disk because I am using two hard drives in a dual-boot. For booting windows and Debian. /boot will be at the beginning of the 2nd drive (sdb). This drive will be 100% devoted to debian. I will then change the boot order in BIOS to have sdb drive boot. This will display a menu asking which OS to boot (windows or debian). See the end of page 2 on this link please: http://www.linuxbsdos.com/2012/07/23/dual-boot-ubuntu-12-04-and-windows-7-on-a-computer-with-2-hard-drives/ >> I am also 'meticulously' reading the debian install instructions as >> well and Debian mentions other available directories such as: >> dev, lib, opt, var, usr, sys --- etc. Please see the list of >> additional directories: >> http://www.debian.org/releases/stable/i386/apcs02.html.en >> >> Question #3 please: >> I am not sure if I need to include 'any' of these additional >> directories (listed above) in my partition scheme. > > The only actually additional one is /opt.

Ok but words like i3, rxvt, X11 are very foreign to me at this point.

Currently I have RAID turned off on my motherboard but I will consider your suggestions. Definitely great advice! > Do not install/use the console-kit-daemon.
