Took me ages to find this thread again!

You have missed a step.

When you get to the point that you have both drives installed, #1 with
Windows and #2 with Ubuntu, then you have 2 ways to proceed.

Either:

[1] use the BIOS to choose which to boot from

Or:

[2] Update GRUB on your Ubuntu drive so that it knows about Windows
and offers you the choice. To do this, boot Ubuntu - using the BIOS to
set Ubuntu's drive as bootable - and then from a terminal type

sudo update-grub

That's about it. Then Windows should be automatically added onto your
GRUB boot menu.
