What exactly is the error with acpi? Copy it and paste it here. Please provide the specification of your laptop inxi -F

    Forgive me if I am slightly on the wrong track here; but I have heard that some machines can boot with acpi switched off so maybe this is an option. I remember reading a Red Hat Linux article about some hardware shipping with buggy acpi firmware. A quick search; and I have found said article maybe it would help in this situation? I am no expert but often find many solutions to these sorts of problems scattered across the forums of Solus and other OS's.

    pomon Its a lenovo g40-80 intel i5-5200U 6gb ram 2.20ghz and hdd. The error was acpi bios error(bug)could not resolve symbol

      Well, according to the link provided by @DJSupertel when starting Live Solus, press Tab and add acpi=off at the end of the line. If that doesn't work, you can try adding noapic or nolapic, or all of them.

        pomon tried doing all of them.
        Acpi=off brings me to a black screen.
        Noapic brings me to my error again thus nothing happened.
        Nolapic brings me to an error but its like a shorter error. There was no failed to mount /sysroot and no emergency mode. Im starting to think its my laptop's problem. Have already tried ubuntu and two solus os versions and still nothing

          You can check it out yet acpi_osi=! acpi_osi="Windows 2009". I asked you to provide a specification. What is your graphics card because the black screen is usually a problem with the graphics card drivers. You may need to add a parameter from modeset.

          Options: acpi_osi=! acpi_osi="Windows 2015" or acpi=off nomodeset

            Updating the BIOS can also cure this problem if the BIOS shipped had buggy firmware. ACPI off would mess up windows if you are trying to dual boot but as said above a black screen is usually a problem with the graphics card. Updating the BIOS was a tip given on a Ubuntu forum question I remember from some time last year when someone was faced with this problem.

            Linux13 When it finally boots, update Solus GNOME via the terminal (It should be listed under "System Tools" in the menu).

              Appreciate all the effort guys. Havent tried anything after doing the acpi thing. Thought that i should take a break. Wish me luck, although i have tested my ram using memtest86 i am still not satisfied so i am goinf to go test it again and see if it is my hardware or im just unlucky and stupid

              Linux13 Have you tried to add what I gave you earlier? Maybe this: acpi=off i915.modeset=1.
              Read about modeset and acp i and try different combinations of entries.

                  pomon this is not really related to acpi error but why do i get a failed to mount /sysroot error.

                    pomon it wont work at all. im going to update my bios and then ill see what i can do.

                        Just noticed that oftenly Shitdows 10 dont really shut down but it hibernates. Check that this is not the case. It can be pretty hard to tell...

                        Funilly I seem to have the same problem in a new laptop. Solus wont boot hanging in a black screen with
                        Invalid acp audio mode: 0
                        Havent really tinkered the bios. Mint boots but trackpad is not working. Havent tested other distros yet.

                        Linux13 Any updates on that?

                          Linux13 where did 2 videos come into play on a laptop? the intel is the main one? Maybe
                          I am seeing it wrong? If there are 2 I would disable one and try it

                              maybe this can help you down in the comments is also your model...you probably need it for another os not for win7 like in video

                              2 months later

                              Axios replying after some time. intel is the main one I guess? it's the integrated and amd is the discrete gpu and
                              no i still haven't fixed this problem.
