Summary | 0016571: UEFI dual boot - Cent OS 8 and Debian 10 dual boot grub not working | ||||
Description | I installed the Debian 10 and then Cent OS 8 now I get the grub screen created by Cent OS 8, I'm even able to see the entry for Debian 10 buster along with advanced options but when I try to boot into debian I get an error. If I use bios feature to switch the bootloader / grub and boot into debian I can use the debian 10 but not Cent OS 8 (not able to boot from debian grub into cent os is I guess Debian issue). Secure boot and UEFI both were enabled while installing both OS. I even tried to re-install the grub from cent OS using grub2-install command but I'm getting error: grub2-install: error: /usr/lib/grub/x86_64-efi/modinfo.sh doesn't exist. Please specify --target or --directory. To resolve above error I had to install package "grub2-efi-x64-modules" but whenever I install this package CentOS just stops booting and there not even a grub screen from cent OS anymore. | ||||
Steps To Reproduce | Enable UEFI Enable Secure Boot Install Debian 10 Buster Install Cent OS 8 | ||||

Error on selecting Debian entry in Cent OS specific grub error: ../../grub-core/loader/i386/efi/linux.c:208:/boot/vmlinux-4.19.0-6-amd64 has invalid signature error: ../../grub-core/loader/i386/efi/linux.c:93: you need to load the kernel first. Press any key to continue... Just to verify that both the kernels are signed in BIOS; I executed the "mokutil --list-enrolled" command and I was able to see the signature for both "debian" and "centos".
