Run memtest86+ V4 on Asus A540L

First you must download Memtest86+ from site https://www.memtest86.com/download.htm , then install on USB via command (Linux):

dd if=memtest86-usb.img of=/dev/sdb

You will change /dev/sdb to the location of your flash drive

If you have installed pendrive, then you run BIOS (F2 Key), and:

  1. Go to [Security] Tab -> and then you’ll disable [Secure Boot Control]
  2. Go to [Boot] Tab -> and then you’ll disable [Launch CSM]. (Compatibility Support Module)
  3. Save Changes

Then you memtest86+ start correctly (if you have pendrive boot on first of course)
