我之前在这里发过这问题，现在已经解决。我正尝试使用闪存驱动器在我的 MacBook Pro 上安装 ubuntu 15.10。具体来说，我遵循这些我通过搜索找到了说明，但是我没有按照本指南的第 1 部分进行操作，因为我使用的是朋友已经安装 Ubuntu 的闪存驱动器。我希望这与我现在遇到的问题无关。
我现在到了第 4 部分：让 Ubuntu 可启动。我到了必须在终端中输入以下内容的步骤：
grub-mkconfig -o boot/grub/grub.cfg
And this is the results that I get:
Generating grub configuration file ...
Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.

cat /boot/grub/device.map

答案1
这应该作为注释更好，但我仍然没有权限。我是 GRUB 的前开发人员。
可能发生的情况是 grub-mkconfig 无法检测到 /dev/sdc1 所需的模块。如果您的驱动程序不包含您的 /boot（grub 存储模块的地方）或要启动的内核文件，这不是问题。
请分享您的 /启动/grub/grub.cfg并将
GRUB_TIMEOUT 的值更改为 10
sdc1 中的文件系统是什么？的输出是什么sudo fdisk -l？在 grub 提示符下输入 c（进入 shell）并输入ls它向您显示的驱动程序？
