Add parameters on OS start up

  • Hi to everyone,

    i just make a clear installation of LibreELEC, but when i try to start the OS, it show the LibreELEC logo and version and give me the error:

    do_IRQ: 0.163 No ira handler for vector

    I know that the solution is to add the parameter "pci=nomsi, noaer" in the GRUB, because a friend of mine do it for me an year ago on OpenELEC, but now i don't know where the GRUB is stored, how to edit it and how i have to write the parameter.

    I have a Ubuntu 10.4 live USB, so i can edit the LibreELEC GRUB from there if it's necessary, but i need a step by step guide.

    I'll wait for your answer, thanks.
