I have acquired some old pcs. I want the newest Ubuntu OS on them.

I have downloaded Ubuntu desktop 18.04.3 desktop amd64.iso and used Rufus, ISO to usb, and cmd line to make a bootable usb on windows vista. None have worked.

The pc that I want to run Ubuntu on is a dell opitplex 760. It’s certainly running windows xp 2002 service pack 3, has 2g memory, 2.5ghz processor and 160gb hard drive. I believe it’s a 32 bit system but not sure.

I have also bought 3 usb sticks and none seem to work. I got the pc once to give me a grub error 15 code but now I can’t get it to show back up. I can restart the system and windows xp works every time.

Please help with the right download and the right settings to make a bootable usb for this system. I would like windows xp off and Ubuntu to take its place.

    Then try i386 iso file: http://releases.ubuntu.com/16.04/ Rufus prompts you which method of copying you want to use: dd or iso. I don't remember what it should be, but try both to be sure. Also, what means none have worked? When grub error 15 code appears? – Gryu Jan 28 '20 at 19:08

    Also make sure you are using bios legacy, not uefi. With 2GB ram, might want to try lighter versions of ubuntu like lubuntu or xubuntu. My newer dell I had to google a bit for bios settings to boot/install from USB. – crip659 Jan 28 '20 at 19:25
  • Thank you both I’ll try the 32 bit downloads with Rufus I have to use Rufus 2.8 because the computer I’m using to write the usb drive is a windows vista once I try I’ll let you know how it comes out thank you – contact Jan 28 '20 at 19:52
  • THANK YOU so I can’t run Ubuntu 18 I had to run Ubuntu 16 on 32 bit thank you everyone! With that being said how can I find out how I can update to the latest os? – contact Jan 28 '20 at 20:35
  • This link should answer, seems to be possible if upgrading. https://askubuntu.com/questions/1127402/is-there-a-32-bit-version-of-ubuntu-18-04-desktop. Should try one of the lighter desktops for better performance on 2GB. – crip659 Jan 28 '20 at 22:03

There are many different Dell Optiplex 760 machines with different CPUs. If you have one with a 64-bit processor, just add RAM and you can run full-up Ubuntu. To find what you have, enter your service tag at the Dell PC Support Site, or open a terminal in Ubuntu 16.04 and run lscpu | grep Architecture

Without a 64-bit processor you will be limited in your choices when it comes to running full-up Ubuntu with the heavy GNOME3 desktop. However, Ubuntu also offers flavors with less demanding desktop environments which sill still run Ubuntu apps.

32-bit flavors of 18.04 include:
