    I Want to Try Ubuntu but I'm Afraid to Lose My Legacy OS!

    So you want to try Ubuntu on your Intel based Mac but don't feel confident going through the torturous procedure of partitioning your hard drive? Lucky for you, there are many programs that will allow you to run a virtual machine within your Mac OS X install. Our focus today will be running Ubuntu, within your Mac, through the popular Parallels Desktop virtual machine software. While Parallels is not free, it is a steal at its current price as it is easier to use on a Mac than the free options that are available.

    As a side note, if you plan on using Ubuntu heavily, you may want to consider partitioning your hard disk for the install to avoid the performance hit you will experience running Ubuntu in a virtual machine. For a Windows PC, your can just slip in the install disk (or usb stick) and get going, the GRUB partition manager comes preconfigured to resize a NTFS partition (that’s a Windows partition to you non-techies out there). Mac users will need to create the partition separately using rEFIt boot manager. A separate comprehensive tutorial for configuring Ubuntu on a mac is available here on Bright Hub.

    Configuring Your Ubuntu VM

    Once you have installed the Parallels program, fire it up and select ''New Virtual Machine''.parralels1 

    parralels2 Select ''Custom Install'', this will allow you to set how much RAM and hard disk space is devoted to your Ubuntu virtual machine. Specify ''Linux'' at the next prompt and allocate how much RAM you want devote to your Ubuntu install. Keep in mind that anything under 256 megs will run a bit slow, and most users report anything over 1 gig as not really giving much improvement. On most machines, allocating 512 megs will give you both a zippy VM and allow you to perform most tasks.parralels set ram 

    Choose ''create new virtual hard disk'' at the next prompt making sure you don't allocate too much room to the VM (Virtual Machine), especially if you will be using the VM for primarily safe browsing. Between 5 and 10 GB should be plenty unless you plan on downloading Blu-ray movie images! Accept the default path, select ''Bridged ethernet'' on the next prompt and make sure to select the same adapter you are currently using in your primary operating system. This can always be changed at a later time if needed. Finally, name your machine and get ready to install Ubuntu!

    The Exciting Ubuntu Linux Install

    parralels-choose-iso The first thing you need to do is to configure Parallels to look for your boot disk, the virtual machine software has it is set to CD-ROM by default, so if you are installing from a USB key or an Ubuntu ISO image make sure to choose that as the installation medium.

    Once that is done, restart with either the boot disk or usb in your computer, and you should see a purple screen. Expect to see this for a while if you are on an older machine. thepurplescreen

    Making Sure It's All Kosher...

    ubuntu-preparingto-install On the preparing to install screen the program will check to see if you have sufficient hard drive space, whether you are connected to the Internet and if the computer is plugged in (for laptops). Being connected to the Internet is only necessary if you plan on installing updates during the install, I do not recommend this unless your Internet connection is fairly fast. Updates can easily be installed post-install at your leisure.

    Allocating Drive Space for Ubuntu

    allocatespace2ubuntu1 This is the screen where we choose the drive space we created earlier. Set Ubuntu to install on the full hard drive here, don't worry, its only using all of the virtual hard drive. If you need more room, remember you can always expand it later.

    Setting Time, Keyboard Layout and Passwords

    Once this operation is completed, the only things left to do are to choose your keyboard layout, set the time zone and set your user name and password. Each screen will prompt you in quick succession. Make sure that your password is easy to remember because you will need it to log in and every time you install or update a program.
