Installing Ubuntu inside Windows using VirtualBox

--> After obtaining Virtual Box.Follow steps below :
  Get a Ubuntu disk image (.iso file). 


--> After you launch VirtualBox from the Windows Start menu, click on New to create a new virtual machine. When the New Virtual Machine Wizard appears, click Next.

--> You can call the machine whatever you want. If you're installing Ubuntu, it makes sense to call it Ubuntu, I guess. You should also specify that the operating system is Linux.

--> VirtualBox will try to guess how much of your memory (or RAM) to allocate for the virtual machine. If you have 1 GB or less of RAM, I would advise you stick with the recommendation. If, however, you have over 1 GB, about a quarter your RAM or less should be fine. For example, if you have 2 GB of RAM, 512 MB is fine to allocate. If you have 4 GB of RAM, 1 GB is fine to allocate. If you have no idea what RAM is or how much of it you have, just go with the default.
Click Next.

--> If this is your first time using VirtualBox (which it probably is if you need a tutorial on how to use it), then you do want to Create new hard disk and then click Next.

--> Click Next again.

--> Theoretically, a dynamically expanding virtual hard drive is best, because it'll take up only what you actually use. I have come upon weird situations, though, when installing new software in a virtualized Ubuntu, in which the virtual hard drive just fills up instead of expanding. So I would actually recommend picking a Fixed-size storage.

--> Ubuntu's default installation is less than 4 GB. If you plan on adding software or downloading large files in your virtualized UBuntu, you should tack on some buffer.

--> Click Finish and wait for the virtual hard drive to be created. This is actually just a very large file that lives inside of your Windows installation.

-->Click Finish

 ----------------------------------------------------------------------------------------
 
-->The next thing to do to make the (currently blank) virtual hard drive useful is to add the downloaded Ubuntu disk image (the .iso) boot on your virtual machine. Click on Settings and Storage. Then, under CD/DVD Device, next to Empty, you'll see a little folder icon. Click that, and you can select the Ubuntu .iso you downloaded earlier.

--> Once you've selected it, click OK.
Then double-click your virtual machine to start it up.

--> Once it's started up, just follow the regular installation procedure as if you were installing Ubuntu on a real hard drive (instead of a virtual one).

--> Afterwards, in order to use your virtualized installation (instead of continually booting the live CD), you have to change the CD/DVD Device entry to be Empty again.
Enjoy Working.!!!!!!

VM VirtualBox

Oracle VM VirtualBox is an x86 visualization software package, created by software company Innotek GmbH, purchased by Sun Microsystems, and now developed by Oracle Corporation as part of its family of virtualization products. Oracle VM VirtualBox is installed on an existing host operating system as an application; this host application allows additional guest operating systems, each known as a Guest OS, to be loaded and run, each with its own virtual environment.
Supported host operating systems include Linux, Mac OS X, Windows XP, Windows Vista, Windows 7, Solaris, and OpenSolaris; there is also a port to FreeBSD.Supported guest operating systems include versions and derivations of Windows, Linux, BSD, OS/2, Solaris and others. Since release 3.2.0, VirtualBox also allows limited virtualization of Mac OS X guests on Apple hardware.
According to 2010 surveys by LinuxJournal.com, and LifeHacker.com, VirtualBox was the most popular virtualization product with over 50% of the vote.
Since version 4.1, Windows guests on supported hardware can take advantage of the recently implemented WDDM driver included in the guest additions; this allows Windows Aero to be enabled along with Direct3D support. Macintosh computers with supported hardware can also enable these new features.

The screenshots below show several impressions while running VirtualBox on Windows, Mac OS X and Linux/UNIX platforms: 

VirtualBox for Windows. Within VirtualBox Ubuntu 10.10 is running. 


VirtualBox for Mac OS X. Within VirtualBox Windows 7 is running.
VirtualBox for Linux/UNIX. Within VirtualBox Windows XP is running.

Please be aware that you should have a minimum of 512 MB of RAM. 1 GB of RAM or more is recommended. 

Comparison to Dual-Boot

Many websites (including the one you're reading) have tutorials on setting up dual-boots between Windows and Ubuntu. A dual-boot allows you, at boot time, to decide which operating system you want to use. Installing Ubuntu on a virtual machine inside of Windows has a lot advantages over a dual-boot (but also a few disadvantages). 

Advantages of virtual installation
  • The size of the installation doesn't have to be predetermined. It can be a dynamically resized virtual hard drive.
  • You do not need to reboot in order to switch between Ubuntu and Windows.
  • The virtual machine will use your Windows internet connection, so you don't have to worry about Ubuntu not detecting your wireless card, if you have one.
  • The virtual machine will set up its own video configuration, so you don't have to worry about installing proprietary graphics drivers to get a reasonable screen resolution.
  • You always have Windows to fall back on in case there are any problems. All you have to do is press the right Control key instead of rebooting your entire computer.
  • For troubleshooting purposes, you can easily take screenshots of any part of Ubuntu (including the boot menu or the login screen).
  • It's low commitment. If you later decide you don't like Ubuntu, all you have to do is delete the virtual hard drive and uninstall VirtualBox.
Disadvantages of virtual installation
  • In order to get any kind of decent performance, you need at least 512 MB of RAM, because you are running an entire operating system (Ubuntu) inside another entire operating system (Windows). The more memory, the better. I would recommend at least 1 GB of RAM.
  • Even though the low commitment factor can seem like an advantage at first, if you later decide you want to switch to Ubuntu and ditch Windows completely, you cannot simply delete your Windows partition. You would have to find some way to migrate out your settings from the virtual machine and then install Ubuntu over Windows outside the virtual machine.
  • Every time you want to use Ubuntu, you have to wait for two boot times (the time it takes to boot Windows, and then the time it takes to boot Ubuntu within Windows).

20 Free Operating Systems that are not Windows


For the last few days, Windows 7 is just about the only OS anyone has been talking about. I figured it was high time for us to share the love and take a look at some other interesting free, downloadable operating systems.

fedora f 20 Free Operating Systems that are not Windows
Fedora 10 (pictured) – One of the few live distros that didn’t have any trouble with the hardware on my MSI Wind netbook. My acid test: can it properly suspend and wake? Yes – and it does it faster than Windows XP, Vista, or Windows 7. OpenSUSE and Ubuntu both failed to resume properly.

Damn Small Linux
– I wouldn’t feel right not listing Damn Small. It’s pretty amazing what you can do with a whole OS that’s not much bigger than most Windows antivirus applications. 50mb gets you Firefox, XMMS, VNCViewer, MS Office Viewer, and much more. It’s also easily extendable through the MyDSL service or by using the apt command.
Linux Mint - While it’s based on Ubuntu, Mint has some features that I think make it a bit more user-friendly. For starters, there are several easy ways to find and install new software including the dead simple Mint Software Portal. Find an app, click the install button, bada bing!


64 Studio – If you’re into digital content creation of any kind – audio, video, or graphics – 64 Studio is a distro worth downloading. It’s packed full of awesome multimedia apps and, contrary to the name, is available for 32-bit platforms as well.
live.linux-gamers.net - One of the big complaints about Linux is “Where are the games?” If you’d like to see some, why not download a live DVD that contains a truckload that you can run without even installing anything? FPS, racing, platformer, you name it – this disc has it covered.
Slax – This has always been one of my favorite light Linux distros. It’s about 200mb and includes plenty of great apps. It includes a really slick boot option as well: to act as a PXE server, allowing other machines on your LAN to boot Slax over the network.
NimbleX – If you’re looking for a lightweight base to run virtual PCs on, check out NimbleX. It’s the smallest distro I’ve seen that comes with Sun’s Virtual Box. You can even customize your ISO on the web site before you download it if you want. Awesome.

haiku 20 Free Operating Systems that are not Windows

Haiku – Inspired by BeOS, Haiku strives to provide an environment that is simple enough for beginners to use, yet powerful enough for more experienced users to enjoy as well. As they say on their web site, Haiku wants to be “free of unnecessary complexities.” There’s also Zeven OS, a Linux distro with BeOS-inspired visuals.
ReactOS – Definitely an ambitious project, ReactOS is trying to produce a free, non-linux environment that is fully compatible with Windows applications and drivers. It’s got a long way to go, but it’s an interesting project to keep your eye on.
Mac-on-stick – Sure, OSX is pretty and functional, but can it fit on a 32mb flash drive? Mac-on-stick is a complete Mac OS 7.0.1 environment that runs on Windows, Mac, Linux, and even Pocket PC. Use it to run old-school apps or classic games like Dark Castle. It’s also part of the Portableapps.Com suite.
OSX86 – No, there’s no link for this one, gang. I’ve included OSX86 (which you can probably find yourself on any major torrent tracker by searching for kalyway) because it’s an amazing example of what an enthusiastic computing community can accomplish. There’s even a customized version floating around that is tailored for the MSI Wind netbook..
NetBSD – If you’re not interested in trying the Hackintosh thing, why not play around with OS X’s foundations? One of the great things about NetBSD is the amazing number of hardware platforms it can run on, including the Playstation 2 and Sega Dreamcast. You may also want to try Jibbed, a lightweight NetBSD livecd spinoff that runs XFCE4.
solaris 20 Free Operating Systems that are not Windows
Open Solaris – The good folks at Sun play a big part in the development of a pretty mean free OS. Open Solaris is incredibly stable and is designed for reliability and network performance. It makes an excellent foundation for NAS devices and servers.

FreeNAS – Speaking of NAS, if you’ve got an old junker around that you’d like to turn into something useful, FreeNAS is a nice option. It’s a barebones distro based on FreeBSD and is designed to turn old hardware into simple network attached storage.
IE Application Compatibility VPC Images – More free stuff from Microsoft? The VPC images include .vhd files of XP and Vista machines that can be run inside Virtual PC to test applications in different Windows OSes with different versions of IE.
VICE – Again not technically an OS, but I’m not sure anyone is really looking to multiboot the Commodore 64 or VIC20 operating systems. The VICE emulator will also run C128, PLUS4, and PET programs.

GeeXboX – Another great use of an outdated machine is to turn it into a media server/HTPC and GeeXboX is an excellent operating system to power it. There’s even an ISO generator that runs on Mac and Windows that you can use to build a customized GeeXboX disc with different themes, languages, network settings, and more.

Untangle – Untangle is a free, open source gateway that is available as both a full-blown OS and a Windows application. The Windows “app” is a nice option if you don’t have the hardware to spare for a standalone gateway machine.

Ultimate Deployment Appliance
– UDA is a slick VMWare appliance that allows you to easily serve ISO images via a PXE environment. I love it. No more griping about badly scratched Vista or XP install discs, I just boot via the LAN interface instead.

gParted – If you’re using a “questionably legal” solution like Hiren’s Boot CD to manage drive partitions, you should give gParted a try. The interface and functionality is very similar to Partition Magic, and gParted is totally free and open source.
