Running multiple Operating Systems usually costs too much, and needs to keep rebooting each time, which makes installing two or three different Operating Systems a complicated and unlikely process. Multiple commercial and free applications could be used to run multiple OS's, like Microsoft Virtual PC, Apple Boot Camp, and there is free software like VMware server, which we will use in this How-to.

  1. 1
    Download VMware Server, you can find a free version on their website.
    Ad
  2. 2
    Install VMware, as simple as installing any program.
  3. 3
    Give your program its first run.
    • On the first run, the program usually asks for a license number, which you could get by request from the website.

    Choose a host. Each time VMware runs, it will ask you to which Host you want to connect, this is very useful if you have a server and you connect to it by entering the IP, in the simple case use the Local Host.
  5. 5
    To add a new operating system, you should make a new image, each image contain one operating system, which is refereed to as "Virtual Machine" in VMware.
    • Example: want to add a Linux Ubuntu image (Virtual machine)

    Here you choose the network type, if your PC has an IP like 192.168.20.12 on the local network, you can give the new Guest OS a new IP like 192.168.20.11.
    • An easier choice is to use Bridged Networking.
