    Installing ubuntu 12.04

    I managed to try the live version with the the nolapic or acpi = off boot parameters. After i installed the OS now i can't boot with the same error i was getting. How can I pass those options to grub?
    Thanks in advance.

    If you enter the boot options in the right place, it will survive the upgrades. See

    If i understood it right, i should edit the file /etc/default/grub

    and add the in the following line:

    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" "acpi=off" "nolapic"
    if i do that, when i update the grup, i get this error:

    "/usr/sbin/grub-mkconfig: 35: /etc/default/grub: Syntax error: EOF in backquote substitution"

    Where is my mistake?
    Thanks again

    Hello, hsaptus.

    I think the line should read
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="acpi=off nolapic quiet splash"
    There must be only 2 double quotes, 1 at the beginning and 1 at the end.

    Kind regards,
