Dual Boot Windows 7 X32 & X64 Steps, Correct?

I am just checking before I do it if the steps are correct.

Q: Why am I doing this?

A: I have both retail versions of Windows 7 x32 and x64 and need to install both on one HDD, I have two unique keys also. This is used for my work machine for software testing.

I have a single SATA 250GB HDD which is a new HDD, completely un-used.

The steps I think are correct are as follows;

* Insert Windows 7 x32 into drive and proceed with setup.

* Click advanced drive options and click New, create the first partition 50% of my full HDD space.

* Click New and create the 2nd partition with the same size as previous.

* Install Windows onto Partition 1 as normal.

* Insert Windows 7 x64 into drive and proceed with setup.

* Install Windows 7 onto Partition 2 as normal.

Use the unique license key for each install, cannot use the same key for both.

Both operating systems are now installed and can be chosen on boot, each has the same available size.

One question I am wondering is does this process create 2 System Partitions for recovery files like it does when doing a single install? If so do I need to incorporate the 200MB size allocated when I am choosing each partition size?

I know this can also be done via disk management after one is installed then shrinking the volume by a max of 50% but I want to know the clean install route as mentioned above.
