Debian and CentOS UEFI Dual Boot - Can't Get Debian To Load
Clash Royale CLAN TAG#URR8PPP
I'm trying to install Debian and CentOS on one disk with a UEFI boot. When Debian boots, I get the error in the image below:
To explain how I attempted to set this up, I'll show what I did with the partitioning. Below is a picture of my initial Debian partitioning (note I left some spare space at the end to put the CentOS "/" mount point on).
After that ran and installed it worked fine. I then put a USB drive in, to boot and install CentOS. When I got to the partition screen, this is what it looked like (before any modification):
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?

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?

### END /etc/grub.d/41_custom ###
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?

sorry you miss-understand me. I am not an idiot, that needs to be told where the images are. I am some one that is giving feedback on you question. To make it a better question. In the hope that someone will answer it. You need to make the images part of the question, so that it is self contained, so that a reader can read it without being sent off, and coming back, and all that effort (If you act on the feedback, then I will read the rest of the question.)

That's right, I still don't understand you. You said "You need to make the images part of the question". There is nothing more that I can do to show you the image other than give the link underneath. Like, what more are you expecting? Is there a way to make the image from the link appear within the post (if so teach me so I can do what you ask man, I have tried to do this for years, but could never figure out how, or if its possible).

I did the first one for you. I followed the link, and right clicked to get a link to the image. Then edited question, clicked add image, and pasted the link.

I'm trying to install Debian and CentOS on one disk with a UEFI boot. When Debian boots, I get the error in the image below:
To explain how I attempted to set this up, I'll show what I did with the partitioning. Below is a picture of my initial Debian partitioning (note I left some spare space at the end to put the CentOS "/" mount point on).
After that ran and installed it worked fine. I then put a USB drive in, to boot and install CentOS. When I got to the partition screen, this is what it looked like (before any modification):
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?

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?

sorry you miss-understand me. I am not an idiot, that needs to be told where the images are. I am some one that is giving feedback on you question. To make it a better question. In the hope that someone will answer it. You need to make the images part of the question, so that it is self contained, so that a reader can read it without being sent off, and coming back, and all that effort (If you act on the feedback, then I will read the rest of the question.)

That's right, I still don't understand you. You said "You need to make the images part of the question". There is nothing more that I can do to show you the image other than give the link underneath. Like, what more are you expecting? Is there a way to make the image from the link appear within the post (if so teach me so I can do what you ask man, I have tried to do this for years, but could never figure out how, or if its possible).

Looks like CentOS's /etc/grub.d/30_os-prober script failed to take into account that the CentOS GRUB uses Secure Boot-compatible linuxefi/initrdefi keywords and omits support for the traditional linux/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's os-prober apparently just copied the configuration lines from Debian's GRUB configuration file essentially as-is, without applying the necessary change. You might file a bug report on CentOS os-prober about this, if someone hasn't already reported it.
