This will write zero's to the entire drive - a bit excessive, and
time consuming. Add count=1 to the command.

It does not put the Windows boot loader one the drive, but it does
create a new MBR.

If the partitions are the same size, you should be able to do:

dd if=/dev/sdb1 of=/dev/sda1

But I still like using parted instead of dd for this. It will handle
any differences between the partitions.

I would defrag before shrinking the partition, but I guess you have
already shrunk it. You are also going to have to boot from the
windows CD, start the recovery console, and run fixmbr. (Or you can
do your Linux install, install Grub, and let it boot Windows/Linux.)
