When booting from Live USB with Ubuntu 18.04.4 image, I've got the following error ~10 seconds after the GNOME shell was loaded:

enter image description here

This error leads to a system shutdown.

I've tried to select Try Ubuntu without installing and Install Ubuntu, both of them are giving the same error.

UPD: This problem still persists (I've tried different ubuntu images and different disk creators). I've also tried to disable acpi with acpi=off in bootloader settings.

My system ASUS ROG Strix GL503GE laptop has the following drives:

  • 256 GB SSD with Windows 10 installed
  • 1 TB HDD with Ubuntu 19.10 installed

  • You have nVidia, are you using nomodeset boot parameter? Have you updated UEFI & SSD firmware? Asus ROG Zephyrus G Ryzen 7 GTX 1660 Ti UEFI update required, nVidia driver required https://ubuntuforums.org/showthread.php?t=2420199 Many also need pci=nomsi boot parameter. https://ubuntuforums.org/showthread.php?t=2414431 & https://askubuntu.com/questions/162075/my-computer-boots-to-a-black-screen-what-options-do-i-have-to-fix-it – oldfred Mar 29 '20 at 18:03
  • @oldfred UEFI is at newest version. nomodeset parameter was added but also didn't work for me. – arturkuchynski Mar 30 '20 at 05:43
  • Both nomodeset pci=nomsi added to Linux line? This user even added more parameters? https://askubuntu.com/questions/694453/new-laptop-skylake-cannot-boot-xubuntu-even-with-boot-parameters – oldfred Mar 30 '20 at 13:43

Boot Live USB using grub from Internal Drive

If you are having trouble booting a Live Ubuntu 19.10 USB made using balenaEtcher, mkusb, Startup Disk Creator, dd or other method that uses an ISO9660 file, you may be able to boot using your internal drives grub.

Try adding the following menuentry to your internal drive's grub menu or to /etc/grub.d/40_custom and then run sudo update-grub.:

menuentry "Ubuntu - flash drive" {
 search --set=root --fs-uuid xxxx-xx-xx-xx-xx-xx-xx
    set gfxpayload=keep
    linux   ($root)/casper/vmlinuz$casper_flavour  file=/cdrom/preseed/ubuntu.seed quiet splash  ---
    initrd  ($root)/casper/initrd$casper_flavour
}

Where xxxx-xx-xx-xx-xx-xx-xx is the UUID of the Live USB.

This method should work for any live or Persistent USB that boots ISO9660 files.
