System and Network configuration • apt and grub-install

Hello,

Debian is the latest 12

As I told, there is no boot sequence
Now, I boot with ubuntu grub menu because I did installed last

If I want boot debian I have to select the bios boot menu at startup
and I have the possibility to choose between

• UEFI debian

• UEFI ubuntu

I did not find a way to allow debian or ubuntu recognize each other kernel
I saved debian certificate in ESP but it did nothing

You can use the boot-info-script command (the Debian version is from the following package: boot-info-script) to get more detailed information about how grub was installed, what versions are involved, and what partitions are involved.

You can share the output of the prvios command in a follow-up post in the body of the message (between code tags) or as an attachment.

Please change the subject of the first post, as it is not about apt or grub-install, but about reports of conflicting grub installations on dual-boot systems; i.e.:

Cannot dual booting Ubuntu with Debian: error: bad grub signature, you need to load the kernel first

Note that the same topic has ben already previously opened (for dual boot of Kubuntu 23.10 with Debian 12):

• Bad shim signature - you need to load the kernel first

Hope this helps.
