3. Download and copy Ubuntu installation CD to your "ubuntu" directory
4. Open VMware Player, choose File -> Open a Virtual Machine, choose the virtual machine from your "minix" directory. If the "I Moved it/I Copied it" question pops up, choose "I Moved it"
5. Do the same for "ubuntu" machine
6. Install Ubuntu. Configure Ubuntu according to "disk_images/INSTALLING_UBUNTU.txt". Close machine after installation.
