Virtualization with Sun VirtualBox

Virtualization with Sun VirtualBox

Many people feel intimidated by Linux. Linux is considered by many to be not meant for ordinary people who find the Windows operating system very simple and user friendly. Installation is perhaps the most difficult part of working with Linux, more so with the complexities of partitioning the hard disk, installing the boot loader, setting up the applications,
A major risk which most people face while installing Linux is overwriting the windows partition with Linux or overwriting the windows boot loader with the boot loader of Linux. Though these pitfalls can be avoided and Linux can be set up to dual boot with windows, it is not so easy.
A very efficient and risk-free approach to setting up Linux is virtualization. Virtualization allows you to set up Linux to run on windows. And that too without worrying about accidentally losing your windows installation.
There are various virtualization solutions available, most notably Microsoft Virtual PC, VMWare, Sun Virtual Box and Qemu.
Here I will give step-by-step instructions on how to set up Linux on Windows Operating System using Sun Virtual Box.
Here the Host Operating System is Windows Vista and the Guest Operating System is Ubuntu Linux 9.04 (Jaunty Jackalope)
