I am trying to migrate Wİndows to Ubuntu.I have prepared bootable USB with rufus. I restarted my laptop and went to the setup page, setting my USB drive as main boot option and disabling all other options.

I encountered the same following problem: Installation of Ubuntu 16.04 from a USB drive freezes I fixed this problem with using acpi=off.

I have erased all disk and made clean installation.On the first opening I have installed development tools(JDK,Netbeans...) and move my files to Ubuntu.On the second opening I get following GRUB menu.

1.Advanced GRUB Options for Ubuntu
2.Ubuntu

After choosing the second option , I get following error.

ACPI Error : [_UPC] Namespace lookup failure,AE_ALREADYEXIST(Z0170031/dswload-378)

ACPI Exception : AE_ALREADY_EXIST During name lookup/catalog failure

ACPI Exception : AE_ALREADY_EXIST(SSDT:xh_rupli) while loading table (Z0170831/tbxfload-228)

ACPI Error : 1 table load failures, 0 successful(Z0170831/tbxfload-228)
Couldn't get size : 0x800000000...e
MODSIGN :Couldn't get UEFI db list

I have done some research on internet find following solutions:

First Solution I closed Secure Boot from BIOS settings but It didn't work.I still get same error.

Ubuntu version : 18.04.1 LTS

  • Thanks. I will try this. I almost forget that question. I have fixed this problem by using nomodeset instead of acpi=off.I have no idea what I have done should I answer my question? – my-lord Nov 01 '18 at 18:55
  • Yes you should answer your own question, and accept it (maybe after a 3 day delay, but not sure if the delay is still applicable at this point). – ubfan1 Oct 26 '19 at 02:59
