Dell XPS 15 9560, BIOS is up-to-date (Feb 18). I'm trying ton install Ubuntu 16.04/17.10/18.04beta from USB thumb drive (SanDisk USB 3.0), but when the installation starts it gives errors:
ACPI Error Namespace llopup failure, AE_NOT_FOUND
Cannot enable. Maybe the USB cable is bad? cannot disable (err = -32)
I tried different USB as well as different USB ports, and also tried Ubuntu 17.10 as well but no luck.
I could proceed to “Installation Type” (but there is no partition) after
acpi=off as kernel param but then it crashes when I try to select “+” or “Change”, so it seems like it does not help. But the partition is empty, so something is wrong.
After a struggle, it seems like I needed to change Raid on to AHCI for SATA setting, but after the change I still cannot reach the installation screen or it just freezes as error occurs
unable to find a medium containing a live file system as shown below:
