Running other distro ISO's from Debian Buster Live USB (Secure Boot)
by kkman007 from LinuxQuestions.org on (#577C4)
I have managed to create a live USB of Debian Buster 10.5 which works with Legacy Boot as well as UEFI Secure Boot.
What I am trying to do/learn is if it is possible to run other distros using either their ISO or extracted files from my Live USB.
For example I am able to use it to boot Ubunto ISO's in legacy mode and UEFI ( without Secure Boot ), but when I try to do the same using Secure Boot, I receive a message saying invalid signature for vmlinuz.
Obviously this is because the USB does not have access to the Ubuntu ISO's internal BOOTX64.EFI.
So my question is; is there any way to include those in a way that will allow booting using secure boot.
As a suggestion, I have been trying to find information about fbx64.efi and BOOTX64.CSV which allow defining a fallback BOOTX64, but I dont think that it will work for my use case.
So am I wasting my time? Or is there a way I have not looked at.
Any help/advice would be appreciated.
PS. Once I know what the limitations are I will finish my work and hope to release the steps I followed to create the Live USB in case of it being helpful to other.
