Here is my encounter with Virtual Box. You may download the iso file the operating system from internet, if you wish to boot them with out burning them to a cd or if you have your iso file in pendrive or external harddrive, and if you want to boot them from the drive directly, the answer is here.
Virtual box is a project developed by SUN. Download VirtualBox software from the link below, for your favourite operating system you are using and boot any operating system from any.
Here in my encounter, i have booted Ubuntu Ultimate Edition, that is as an downloaded ISO file in my home directory. Download the Virtual Box deb package from,
And then install it just by double clicking the deb file. You can start the Virtual Box software from the menu Applications->System Tools->Sun xVM Virtual Box. As Virtual Box requires some write permissions, its better to start in the command using su. So, move to the terminal and give the command
rosarioarun@ros-lap:~$ sudo VirtualBox
In the Virtual Box Window,
Now the Virtual Box Main Window will appear back.
The ISO that i wish to boot is in the location
/home/rosarioarun/Desktop/ultimate-edition-1.8-x86/ultimate-edition-1.8-x86.iso
Click on the Name you just created (Ultimate) and click Start. Read the Capture info and click ok.A wizard will appear.
Virtual Box Software with Inserted Bootlist
The OS will be booted as a separate window, you can capture and uncapture to go inside and come out the new OS booted.
OR, Select the Name and click Settings,->CD/DVD-ROM-> ImageFile and select the Image file u wish to boot. And click Ok.
Now click Start to boot the new OS.
After Booting Ubuntu Ultimate
Inside Ultimate with VirtualBox
Virtual Box is a community delovped project, by SUN for the purpose of OS Virtualisation. That is, any other operating systems can be booted inside other operating systems inside a virtualisation window. The Virtual box software will manage the resources required for the newly booted software and the currently running software. It will allocate the free resources within itself, to boot the new operating system virtually.
Presently, VirtualBox runs on Windows, Linux, Macintosh and OpenSolaris and many other guest operating systems. So this includes almost all most frequently used operating systems.
With Virtual box you can boot Guest operating systems in USB, Portable hard drive, or ISO images of operating systems in any host operating system. That is you can boot the downloaded iso images of opertaing systems(linux) in live -cd mode without burning them to a cd.
Normally most the linux distros comes with gcj, which is a Java compiler for gnome. Most of the java programmers prefer only jdk. So how to compile and run a java program in linux. Download the latest jdk from the sun website. (jdk-1_5_0_16-linux-i586.bin for a x86 system)
And then to install jdk use the following
rosarioarun@ros-lap:~$ ./jdk-1_5_0_16-linux-i586.bin
This will extract the jdk and give an folder in current path as, jdk-1_5_0_16, this folder will have all bin, lib directories required by the javac compilation and execution.
All the contents inside this directory will be same as the conents when you install the jdk in the windows. You will have a question that, why not i use the extracted jdk folder in windows, in linux to compile the java program in linux.
Both the extracted jdk folders in windows and linux are not the same, the difference is the extracted contents in windows will have all exe file, where as in linux it will be binary files.
That is javac in windows will be javac.exe and in linux it will be javac.bin
Now to set the path proceed as below
rosarioarun@ros-lap:~$ PATH=$PATH:/home/rosarioarun/jdk1.5.0_16/bin/
this is just a single line script to set the path, you can view the PATH variable using echo
rosarioarun@ros-lap:~$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/rosarioarun/jdk1.5.0_16/bin/
Now you can compile the java programs using javac and run them using java commands.

I had a chance of spending a day with 10 persons from Tanzania. An unforgettable day 25th July 2008. Had a wonderful time spending with them and taking them all around my native Kanyakumari.A day was not enough with them.
A special day
And In that team, Father Maina, Eric, And Frank were more interested in the way i was using Ubuntu(Hardy). Frank was more interested and wanted to intall Hardy in his New laptop(HP), which was preloaded with Vista. So i used a Hardy dvd, and booted the laptop in Live cd mode and used gparted(Gnome Partition Editor) to partion the hard drive into four partions…
He had a thought that its not possible to install other OS, with out complete formatting and partitioning the hard drive. (As there was no partition at all and Only C drive and it has Vista). He was worried that his Vista and Recovery part to go off… I took of all his worries about hin his lap… I partitioned, Installed Ubuntu with no loss in Vista or recovery part… Hardy Live CD is more power ful, also gparted is fantastic. Partion your new laptops with out loss of any data with Ubuntu Live CDs. Happy that i imported the Power of ubuntu and linux to few people.
Me accessing my DataOne broad band wireless in my hardy(ubuntu 8.04). For the post two year Iam using Dataone.. But I was not sure whether the wireless port in my modem was Input port or Output port. I tried connecting my Lap after purching my Lap. I didnt know exactly what mode to use in my admin setup page for accessing… I was randomly trying one after the other.. And got it at last.
My Interface Setup in my admin page is in PPoA/PPoE mode, with the username and pasword defined in the router setup page itself. And my Cute hardy scans for the Wireless Lan and connects automatically leaving me no work now a days. My Hardy is always cute, When my boot process is over Iam ready to surf my Net, provided my Dataone modem is ON.
