Installing W2KPro on a WXP system

Hello,

I would like to know how to install W2K in a PC already running WXP, so they both share the computer just like when you have W2K running and then install WXP (inverse operation is cancelled by the WXP installation program claiming that theOS is older than the currently installed).

This was asked by two top executives in my company, and I do have two extra hard disks to install W2K totally isolated from WXP. The idea is to have the classic menu at the beginning asking me which OS want to load. (I know this is easy when you set up W2K and after WXP).

Thank you guys in advance for your comments and suggstions,
