对 grub 和 grub.cfg 的更改将被忽略

对 grub 和 grub.cfg 的更改将被忽略

我对 Linux 完全陌生,所以这可能是我所忽略的一些简单的东西,但我已经用尽了所有搜索选项,但没有任何效果。

我全新安装了 Kodibuntu 并进行了更新(sudo apt-get update && sudo apt-get upgrade)。因此,截至 2016-08-17,该机器现在运行的是最新的 Lubuntu 14.04。我遇到的问题与 Lubuntu shell 有关。我无法让启动时的 grub 消失。自安装以来,它一直存在,并且在两次全新安装后仍然存在。grub 存在是一个问题,因为机器是通过触摸屏和遥控器控制的,因此 grub 中没有选择任何内容的选项,并且 grub 永远不会超时。

当我启动时,我会看到以下选项,但没有超时计数器或任何其他内容:

[  ] Ubuntu
[  ] Advanced options for Ubuntu
[  ] Memory test (memtest86x)
[  ] Memory test (memtest86x, serial console 11520)

“grub”的内容:

我按照网上找到的几种“解决方案”操作,但似乎都不起作用。我更改了 grub 文件,从 /etc/grub.d 中移动了几个文件(编号为 30),然后运行“sudo update-grub”,看到“grub.cfg”更新为上面显示的内容。我原以为 grub 中不会再有 memtest 之类的选项,但它们仍然出现。

此外,设置“GRUB_HIDDEN_TIMEOUT_QUIET=false”和“GRUB_TIMEOUT=1”没有效果。

最后我尝试了 grub-customizer,但无济于事。我对 grub 或 grub.cfg 所做的任何更改似乎都没有任何效果。

有人知道我怎样才能让 grub 超时(或者更好的是,根本不出现)吗?

似乎 grub 以某种方式被强制执行。再次安装 grub 使其符合 grub.cfg 中的内容,但它确实删除了之前的启动画面。

再次安装完成:

sudo grub-install /dev/sda
