ACPI Errors - Ubuntu 16.04/17.04 can not be installed

Solution 1:

On my DELL XPS 9560 I had to:

sudo nano /etc/default/grub

Then add acpi_rev_override=5 to GRUB_CMDLINE_LINUX_DEFAULT:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_rev_override=5"

Run sudo update-grub.

Profit (hopefully it will work when you reboot, and rev override is better than turning off ACPI completely. Also I recommend you to update Kernel at least to 4.14.)

Solution 2:

Not sure if this is exactly the same problem you had, but a few days back, after a windows update my Linux Mint stopped working, with ACPI AE_NOT_FOUND errors. Turns out, the reason was that it tried to mount NTFS drives on boot, and the windows update switched "fast boot" back on, which makes the windows boot time faster, but also causes an inconsistent state on NTFS partitions (among other things as I understand, this was just my case), rendering them inaccessible to any other operating system, as the "missing parts" from the consistent state of the partition are stored in a data structure internal to, and only readable by windows.

As this question is almost a year old, this might not be useful info to you, but your question is on the first page when researching similar problems, so it might help a few people out.
