Is it a NT based version like Windows 2000 or XP?

If so there is a real easy way to do dual boot with a utility called Bootpart. It's what the old Corel Linux used to do dual boot with.

It works with the Boot.ini menu.

I used Bootpart to access Knoppix after I installed it as a dual boot setup on my system. It is so simple to use, it places the command you want into your boot.ini file for you.
