Windows 7 Home Premium 64bit & Windows 7 Starter 32 bit (partitions)

I have just purchased a new pc that came with Windows 7 Home Premium 64-bit, which wont run my company software, which was made in 1995, 16 bit.

This 16bit software ran fine on my previous pc, which had Windows 7 Starter 32-bit. But the 64 bit Windows 7 version wont run it, I cant use Windows XP Mode on my version of Windows 7, need Pro - Ultimate Version.

I want to install and run the Windows 7 32-bit I have, on my new pc (I still have the installation disk) on a seperate partition and keep the 64 bit version to.

Is this possible to install both 32 bit and 64 bit versions of Windows 7 and then select which to run when the pc boots?

Any advice would be greatly appreciated, James

YES, take a look at this tutorial, replace vista with Windows 7.

Dual Boot Installation with Windows 7 and Vista

Thank you theog, I will be following that tutorial, it is very helpful, but I have two questions:

1.) How big should I make the partition for Windows 7 Starter 32 bit? Is there a tutorial to do this?

2.) Will I be able to install Windows 7 Starter 32 bit, from the Windows 7 disk that I got with my previous PC?

1) Step 2 of the tutorial.

2) if retail YES, If OEM manufacturer's NO.

3) one license one PC install. for dual boot two license need,
