Many Windows users would like to taste the different versions of Linux OS. There are ample of Linux Operating System available for free to download as ISO image file. Some of them are Ubuntu, Kubuntu, Lubuntu, Bodhi, Mint versions. Each of the Linux OS is having different features to explore. Every OS comes with versatile specifications and the users loves to engage in it which is subjected to their ideas and interest. 



If you are one of them who like to play with Linux on your PC or Laptop, while installing the Linux OS especially Ubuntu versions, you may face the installation problem. During installation, the OS get installed up to 69-73 % and then it get stopped. The error is called as errno 5. 

[Errno 5] Input/output error

This particular error is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment.



I re downloaded the ISO several times, checked the MD5 right after the download and MD5'ed the burned CD (burned at 4x). Everything seemed to be alright, but this message always occurred - around 69-73%. 

I browsed over Internet and found no solution for this. My Laptop is very new and there is no problem while using Windows 7 and 8. The hard disk and RAM everything seems to be fine and normal. Then I decided that the problem is within the ISO file image. I just tried to overwrite the image file by using Poweriso software and surprisingly it works for me. So now I'm going to teach you the procedure for reconstructing the Linux OS ISO image file. There is no risk involved in it. Follow the instructions given below:

  • Install and run Poweriso.
  • Click on Open.
  • Search for ISO image file which you have saved on your computer and then click on Open.
  • Then choose File > Image Properties. A new dialog box will get open. 
  • Check the boxes ISO9660+UDF for CD/DVD file system.
  • Check the Long(221) radio button for ISO9660 file name.
  • Check Enable file optimization box for Miscellaneous.
  • After that click Ok.


  • Click on File > Save as and save the file.
  • Then click on Yes to overwrite the file.
I used Poweriso full version to overwrite the image file. The free version has some limitation. It reconstruct the file up to 300 MB while overwriting. 

Alternatively you can try Imgburn software which is a freeware. It can do the same function as Poweriso. I will make another post on how to use Imgburn to solve ISO image file error.

To Sum Up

Finally burn the ISO image file to USB or CD/DVD. Enjoy using Linux on your computer system. Smiley
