First put the CD of the second operating ssystem of your choice into the CD-ROM drive of your PC. Then, restart your PC and login to your bios setup to make CD-Rom drive first in the boot order. Save and exit.
Click on any button when prompted and copying of the setup files automatically begins.
WARNING!!! Do not select format drive at all, please this will lead to the loss of your data. Choose install into another folder, this will make the former operating system and the new operating system to be existing side by side.
The rest are just simple information you put and desired user name of your choice. When the installation is completed and you restart, you will see the two operating systems and you can always choose which one you want to login into. All the best
There is utilities to do this. But also you can do with installing like a VM(virtual machine).
