我正在尝试使用 UEFI 引导在一个磁盘上安装 Debian 和 CentOS。当 Debian 启动时,我得到下图中的错误:
为了解释我是如何尝试设置的,我将展示我对分区所做的工作。下面是我最初的 Debian 分区的图片(注意我在最后留下了一些空闲空间来放置 CentOS "/" 挂载点)。
之后运行并安装它工作正常。然后我插入一个 USB 驱动器来启动和安装 CentOS。当我进入分区屏幕时,它看起来是这样的(在进行任何修改之前):
I then made one 20GiB partition for the / of CentOS. Additionally, under the Debian partition section, I modified the /boot/efi partition to have the "mount point (see far right of the image)" of /boot/efi. This then seemed to duplicate itself over to the CentOS partition section. The result is shown below:
Upon boot, I see two options, one for CentOS and one for Debian. If I select CentOS it works fine. If I select Debian, I get the error shown in the first link of this post. My question is why?
My EFI directory is below.

UPDATE - Got A Working Solution, but not happy how I got there (I would like to someone to tell me why my system ended up this way) : In my /boot/efi/EFI/centos/grub.cfg file I manually edited the lines under the Debian menu entry (or sub-menu entries) starting with the word "linux" or initrd" to the words "linuxefi" and "initrdefi" respectively. I can't understand why I've had to manually edit this grub file to make my debian system boot. I must be doing something very wrong right from the installation/setup stages of the operating systems for me to run into this problem. What is happening?
Looks like CentOS's
/etc/grub.d/30_os-prober
script failed to take into account that the CentOS GRUB uses Secure Boot-compatiblelinuxefi
/initrdefi
keywords and omits support for the traditionallinux
/initrd
ones. (Or maybe the support would be available as a GRUB module, but Secure Boot requires all executable code to be loaded to use UEFI standard executable/library formats, which GRUB modules are not.)Debian, on the other hand, uses the traditional
linux
/initrd
keywords because of their strong pro-Free Software (and consequently anti-Secure Boot) stance.CentOS
os-prober
显然只是按原样复制了 Debian 的 GRUB 配置文件中的配置行,而没有进行必要的更改。os-prober
如果有人尚未报告,您可以在 CentOS 上提交有关此的错误报告。
