How to install Ubuntu on the computer
- First, you will need to download the current version of Ubuntu at http://www.ubuntu.com/download/desktop. Select your architecture (32-bit vs 64-bit), and click the big orange button. If your computer has at least 2GB of RAM, select the 64-bit version of Ubuntu. If you are unsure of the flavor you need, select 32-bit as it will run even if you have a 64-bit processor. You may also download any distro release, such as Kubuntu or Xubuntu.
- Next, you will be downloading a large .iso file, about 800MB-1GB. It can take up to a few hours, depending on your connection speed. Let the file download. Then, you will be burning it onto a DVD or LiveUSB. The Ubuntu 14.04 .iso file is too large to fit on a CD so you will need to either burn it to a DVD or else make an Ubuntu live USB using a flash drive that has at least 2GB. (links are for Windows if you are switching from another operating system to check the “Easy ways to switch to Ubuntu” section on the download page.)
- If you are using Windows 7 or higher, you may double-click this file (assuming you don’t have another program associated with it). Otherwise, install ImgBurn (sadly, not open source). You may also be able to right-click and select ‘Burn to Disk’.:

And if you want to make your pendrive bootable then you can also use the Rufus toll. get the Rufus tool from this link https://rufus.akeo.ie/
- You now should have burned your disk. If you open the disk using your file manager, there should be a bunch of files like:
poolamong others. If you have just one file on the disk with the same name as your ISO, make sure you are using a disk burning utility. Do not just drag and drop the ISO file. It will not work.
- Now, put the disc back in your optical drive, and reboot your computer. On a PC, you should have a key like Delete, F2, F10 or another key that will get you to your boot sequence menu. You can enter your BIOS menu by pressing one of these keys as soon as the motherboard splash screen appears when the computer is booting. Otherwise, consult the manual for your computer or BIOS and look for something similar to boot from external media or choose a startup disk (⌥ or Alt on Macs) to find the key that is needed. Follow the screen prompts to boot from the optical drive your new disc is in.
- Assuming you are not booting UEFI, press Shift once you get a purple screen with a picture at the bottom. Select your language with the arrow keys and Enter. Now, you should be confronted with a menu. You may try Ubuntu without installing, or you may install it. If you want to try it, choose “Try Ubuntu without installing“, try it, double-click the Install Ubuntu icon on the desktop, and continue with this guide. Note that this test version is slower because it is running from a CD/DVD/USB, not your hard disk. Some versions of Ubuntu will give a graphical menu for this step.
- Now, you will be confronted with a checklist. You may safely disregard the second option ‘Install this third-party software’, though Adobe Flash Player and some proprietary video codecs may not work unless you enter the commands at the end of this guide.
- Now it is time to partition your hard disk. If you want to avoid losing data or dual boot, this step is crucial. If you want to just clear out whatever is already on your hard disk, and use all of the space for Ubuntu, select that option, and skip to step 10. If you want to dual boot and trust the Ubuntu installer (not recommended), select the option to install side-by-side, and skip to step 10. If you want to manually set up dual boot, select the choice for advanced partitioning and proceed to the next step.
After you finish all these steps, connect to the internet, open the terminal (Ctrl+Alt+T) and run these commands:
- sudo apt-get update && sudo apt-get dist-upgrade: Run this command to update and upgrade ubuntu Operation system.
- sudo apt-get install ubuntu-restricted-extras: This will update the packages on your system and install codecs for proprietary files with restricted copyright (MP3, AVI, MPEG, Microsoft fonts) and Adobe Flash Player.
NOW YOUR UBUNTU OS IS INSTALLED ENJOY IT….(“_”)
