I've probably missed something but I can't find the memtest option when booting from my Ubuntu 12.04 Live USB.

Could someone please tell me how to get to it?

    If you have an UEFI bios and you want to test your memory for errors you need to downlaod the seperate image from memtest86.com/download.htm. The utility on the Ubuntu live CD/DVD/USB does not work with computers with a UEFI BIOS. – Luckyrings Feb 21 '13 at 20:03

You need to boot from live CD or USB. Press and hold any key while your computer is booting.

Press 'F6', a language menu will pop up, select English and press enter. You will then be presented with the option menu.

The options will be

  • Try Ubuntu without installing
  • Install Ubuntu
  • Check Disk for Defects
  • Test memory
  • Boot form First Hard disk

If you select Test Memory you will be presented with another menu that will allow you to select which test(s) you want to run.


F.Y.I. Check Disk for defects will check the installation media for defects(not the hard drive)

  • I don't know whether that applies to Ubuntu 12.04 but with either 14.04 or 16.04 I had no luck seeing a "memory test" option when booting from a Live USB created with "USB Creator" (command line: usb-creator-gtk). Instead, when the live USB was created with UNetbootin: unetbootin.github.io. See this relevant answer: askubuntu.com/a/848772/89663 – Marcus Junius Brutus Nov 13 '16 at 4:32
  • I also solved by directly downloading memtest and installing on usb with rufus – elect May 24 '17 at 11:01
