I have ASUS X540U laptop and I am trying to install Ubuntu 18.04LTS on it but every time the installer reach the detecting hardware stage the progress bar freeze and after couple of seconds it crashes. I did searched for solution on Google and found that I have to disable secure boot but it is already disabled. how to solve this problem Note: I am installing Ubuntu side by side windows 10


I have the same laptop!

In the black GRUB menu that shows briefly, when highlighting the installation option or the "try Ubuntu" option:

  • press the e key (for edit)
  • where it says "splash ..." put "splash pci=noaer ..."
  • press ctrl+x key combination to boot

After installation, open the Terminal application and type:

sudo dpkg-reconfigure grub-pc (or maybe grub-efi-amd64 ?)

There, press Enter and when it says "Linux default command line" you should add pci=noaer, so it should end up like this:

quiet splash pci=noaer

If you don't do that quickly after installation, your hard disk will get full because of log messages in /var/log/.

    I had the same problem with ubuntu 20 and intel i9. The new thing, besides the processor, was a wifi card. The instruction that was provided solved the problem – wmora2 Aug 11 '20 at 22:55
