How to Install Ubuntu?(Install Inside Windows)

/ Labels: , /

Many of you would have installed WINDOWS XP or WINDOWS 7 in your systems but have you ever tried to install UBUNTU or any other LINUX flavours? If you try to install UBUNTU by BOOT-TIME installation, you will come across some problems and most of you will be not in a situation to install it successfully and come up with a conclusion saying WHAT THE HELL MAN?, I TRIED TO INSTALL UBUNTU BUT ITS INSTALLATION STEPS ARE SO DIFFICULT AND IT IS HIGHLY RIDICULOUS. But actually, you are wrong. Installation is so easy and there is no need of sitting in front of computer during installation time.



How actually you can install UBUNTU?

Ans) There are 2 methods by which we can install UBUNTU.




  1. Boot-Time Installation.

  2. Install Inside Windows(Only if Windows OS is installed in your computer)


Here, i completely deal with Install Inside Windows method since it is very easy. Not saying Boot-time installation is difficult, but there has to be some work which has to be carried out by you to install. This needs prior knowledge. And there is also some problems if you install UBUNTU in Boot-Time installation method. Main problem is GRUB load error. If you have observed, the OS will be searched and loaded into memory by Boot-loader(Windows). Exactly in the same way, in UBUNTU the loader is called as GRUB. If you un-install UBUNTU directly(i.e by directly formatting your previously installed UBUNTU drive) you will face problem saying GRUB LOAD ERROR. This means, the MBR(Master Boot Record) has been corrupted or the OS was un-installed in a wrong way. And also the mounting of the drive as a "/" file system and providing a swap-space task will be not known to many people.  Thus to get rid from all these problems and install UBUNTU in more successful and easy way is Install Inside Windows.


Install Inside Windows needs Windows as a Master OS. Master OS means, the loader and the Boot Menu is directly or indirectly connected with WINDOWS. Since this is a easiest method to install UBUNTU, i prefer this type of installation. Well, the steps for the installation of UBUNTU by INSTALL INSIDE WINDOWS method goes as given below:---





  • Put your UBUNTU installation disc in you CD/DVD reader.

  • After Autoplay, a window will be popped out and 3 options will be shown to you. Select Install Inside Windows option.(Same for 9.10 and also for 10.04)



  • In a new window, select the harddisk drive and the installation size(Preferably 8GB) and also enter the password(Do not forget the Username and Password at any cost).

  • Setup copies the installation files to your drive and after copying, it asks for reboot of the system. CD will be ejected out from the DVD reader.

  • After restart, select the UBUNTU option.


And now you make sure that internet is switched on. Installation without internet will not install CANONICAL manager or the Canonical application installer. Thus, without fail, turn on internet during installation process.(**This process can be carried out even after complete installation).

Installation takes 20min's.  After complete installation, login with the username and password which you gave. You can configure your UBUNTU now. Configuring of UBUNTU posts is also posted in this blog.

If  you try to install something from terminal and if it says something saying. Couldn't find files, then no need to worry.  Just go to terminal and enter this. (Thanks to sudarshan).

sudo apt-get install update

You will be done with this. Everything will be completely fine.

Installation guide of OpenGL API in Ubuntu/Fedora

/ Labels: , /

Many would have installed OpenGL, an API(Application Programming Interface) for writing applications that produce 2D and 3D Computer Graphics.


Installation of OpenGL in Linux platform is different and installation in WINDOWS is different. So, some set of steps has to be followed while installing OpenGL in LINUX platform.


Steps goes like this:--


First we need to install the IDE(Integrated development environment). Here, we use CODE::BLOCKS IDE.  To install, open the terminal and type the following command.


sudo apt-get install codeblocks



What actually happens when u execute this command?

The application name specified in the command will be checked in the repository and then the application gets installed by downloading the installation files from the internet or from the pre-installed folder which contains installation files.


Now, IDE is ready but we have to install GLUT(OpenGL Utility Toolkit).  We have to pay for installing GLUT but FREEGLUT available in the net. So, we can install this by the following 2 commands. Enter these following commands in the terminal.



sudo apt-get install freeglut3

sudo apt-get install freeglut3-dev



GLUT files will be installed in /usr/include/GL/   directory.



Once the API is successfully installed, next step is to configure it.

Steps:--



  • Go to Applications-->Programming-->Code::Blocks IDE

  • Then, go to Settings-->Compiler and debugger.

  • Open Linker settings tab. Then, in the bottom, you can see the ADD button. Click on Add button and then type glut and click on ok.  In the same way, type as GLU and GL in Linker settings tab.



FreeGLUT is installed now.


Now API is ready to execute the programs.


Type the program and if you come up with any problem saying cannot find lXxf86vm, then no need to worry. Just go to terminal and type the following command and you are done with that.


sudo apt-get install libXxf86vm-dev


Now, run the program and it must execute.


Any problem or clarifications regarding this post can be posted in the comment panel or email to srikanth.gundaz@gmail.com.



Thank you. :)
