I bought a new to me Lenovo desktop that has a similar partitioning
scheme. except for the D: partition. I used the gparted live CD from:
http://gparted.org/livecd.php
and carved out my desired Debian partitions from the large C: partition
and left all the other partitions alone since the computer is still
under warranty. I never booted Windows past the activation screen as
once I presented with that, I rebooted with gparted live and was on my
way.

So far no issues here although it seems that the update-grub script may
offer some sort of complaint once in a while. I've not had any problems
booting into Debian with this arrangement.

I went straight for the gparted live CD which is a minimal desktop
version of the Debian live CD. I used the amd64 version and it worked
very well. As I recall, I chose to align on cylinders when setting up
the partitions in gparted. Perhaps this was a mistake but it seems to
be working just fine for me.
