I have a problem with installing Ubuntu on my desktop computer.
I had Ubuntu 16.04 and Windows 10 dual boot. After one update of Windows, the Ubuntu installation disappeared.
I tried to install it again with Ubuntu Live USB but when I clicked on 'Install Ubuntu' or 'Try Ubuntu without installing' I got the following errors:
[ 0.016192] ACPI Error: [\_SB_.PCI0.XHC_.RHUB.HS11] Namespace lookup failure, AE_NOT_FOUND (20150930/dswload-210) [ 0.016195] ACPI Exception: AE_NOT_FOUND, During name lookup/catalog (20150930/psobject-227) [ 0.016222] ACPI Exception: AE_NOT_FOUND, (SSDT:xh_rvp08) while loading table (20150930/tbxfload-193) [ 0.021348] ACPI Error: 1 table load failures, 7 successful (20150930/tbxfload-214)
This text is repeated on the whole screen and after the first time it seems blurry as if there are video card issues.
The same Ubuntu Live USB works fine on another PC.
I tried also with Ubuntu 17.04 – still the same errors.
I deleted Windows installation as well and tried to install Ubuntu again.
Then I tried Windows installation and it installed correct.
After a lot of researching in the web, I reached to the conclusion that I have to turn off ACPI in order to install Ubuntu. So I did it. It got installed but it behaved strange, the resolution could not be changed and it started to restarts repeatedly. So I deleted the installation again, considering turning ACPI off was not a good solution.
Has anyone ever had the same or similar problem? What are these errors displaying? How to fix them?
Any help would be greatly appreciated.
