Ubuntu inside Windows can't be more easy :)

Yesterday I tried installing Ubuntu inside Windows, it was so easy that I was tempted to write down steps for any future reference:

Required stuff:
1. 512 MB of RAM

2. Ubuntu - Download the ubuntu image of whichever version you want
File size: ~700Mb File format: .iso
If you have fast internet access it might just take a couple of mins
http://www.ubuntu.com/desktop/get-ubuntu/download
Else if your internet gets interrupted every now and then you might consider downloading
it through bit torrent

3. VirtualBox
Depending on your system version/configuration virtualBox can be downloaded from here
http://www.virtualbox.org/wiki/Downloads


Once the above downloads are ready follow the article for step by step installation

Just the follow up of the above post to run virtualBox in fullscreen mode:
1. Install Ubuntu on VB.
2. After install and restart, go to the 'Devices' menu for VirtualBox.
3. Select 'Install Guest Additions'.
4. Open Terminal in Ubuntu.

Type:
cd /media/cdrom0 (this puts you to the cdrom directory where you just mounted guest additions)
Press enter then type:
dir (this shows you what's inside this directory.)
Press enter then type:
sudo sh ./VBoxLinuxAdditions-x86.run (this is what you would type if you have an x86 machine, typical. If you have an AMD use that one, and so forth.)
If this steps doesnt work for you try locating the file in following structure and run it VBOXADDITIONS_W.X.Y_Z/VBoxLinuxAdditions-x86.run

5. Wait for update to complete.
6. Once complete, shut down Ubuntu.
7. Restart VirtualBox
8. Boot up Ubuntu.
9. Once booted, press cmd+F for fullscreen or cmd+L for seamless.

There u go!
