I recently decided to install Ubuntu on my computer for a project I'm doing, I downloaded the 64 bit version of Ubuntu from the official website and burned it onto a DVD, however, after the installation, I noticed (through the system settings) that the OS was only 32-bit

In case I had made the mistake of accidentally downloading the 32-bit ISO, I went to the Ubuntu website and downloaded the 64-bit version and burned it to a memory stick. I then proceeded to re-install the OS, but it still gives me the "32-bit" in the system settings.

Can someone please tell me What I am doing wrong?

Although I am certain that my PC architecture is 64-bit, I'll include details of my setup, just incase you think I may have made a mistake:

Processor: AMD A6-5400K APU with Radeon(tm) HD Graphics × 2 (in other words, its a dual core)

Motherboard: Asus F2A85-M PRO

Ram: 2x Kingston 4GB DDR3

Also, I got the .ISO from this address: http://www.ubuntu.com/download/desktop

Iso name: ubuntu-14.04.1-desktop-amd64.iso

Thank you very much in advance :)

  • Welcome to askubuntu! Please edit your post and add the filename of the ISO you downloaded and the link you downloaded from to your post. – Elder Geek Oct 30 '14 at 19:42
  • @ElderGeek Ok, I have updated this post, you can find where I downloaded this from and the .iso image name just underneath my PC specs :) – Leethom Oct 30 '14 at 19:56

  • @Mitch Thanks, but I already added that to my Post – Leethom Oct 30 '14 at 20:18
  • add the output of uname -a please – squareborg Oct 30 '14 at 20:20
  • @Shutupsquare I'm sorry, I don't understand, Im fairly new to Linux btw – Leethom Oct 30 '14 at 20:29
  • Okay just open a terminal, and type uname -a – squareborg Oct 30 '14 at 20:34
  • Then add the output of that to your question. – squareborg Oct 30 '14 at 20:34
  • Downloading the 64-bit ISO from the link you provided and checking the md5sum matches 119cb63b48c9a18f31f417f09655efbd

    ubuntu-14.04.1-desktop-amd64.iso. Why do you think you have a 32 bit OS? Are you possibly dual booting both 32 and 64 bit versions?

  • @Shutupsquare OH! you mean run that command in the terminal and tell you the output! jeez I have a long way to go with Ubuntu :/ Anyway, the output is as follows: "Linux Arcade 3.13.0-39-generic #66-Ubuntu SMP Tue Oct 28 13:31:23 UTC 2014 i686 athlon i686 GNU/Linux" Where it says 'Arcade' is the name of my Computer, as that's the project i'm using it for :) – Leethom Oct 30 '14 at 21:04
  • @ElderGeek When I go to the 'Details tab in the system settings, it tells me that my OS type is 32 bit – Leethom Oct 30 '14 at 21:07
  • Open a terminal enter the directory that you downloaded the iso to and and issue the command md5sum ubuntu-14.04.1-desktop-amd64.iso and add the result to your question. Thank you! – Elder Geek Oct 30 '14 at 21:15
  • @ElderGeek Ok then, I shall re-burn the ISO to my memory stick (making sure its the amd64 version this time) and shall attempt to re-install the OS, I'll let you know how I get on. Thanks for your help – Leethom Oct 31 '14 at 16:10

Your uname output indeed indicates a 32 bit OS, It appears that you accidentally flipped the dropdown on the page you provided from 64 to 32 bit.

My uname output from the 64-bit ISO link that you provided ends with X86_64.

You should check the md5sum of your download to insure it matches before you re-burn.

You can find references to the md5sum here: MD5 hash for ubuntu .iso (14.04 through 16.10)
