Kernel not recognized as bootable UEFI binary #130

x86_64 Describe the bug

Unable to boot live iso in uefi due to firmware being unable to recognize the kernel as a uefi executable To Reproduce

1) put iso in usb 2) boot into uefi shell 3) try to let it boot via startup.nsh

Expected behavior

being able to boot in uefi mode Logs

Additional context

trying with MocaccinoOS-XFCE-0.20230707.iso.tar.xz from 1.3 github release the only uefi related file is startup.nsh containing commands to launch the kernel I've attempted to run the kernel manually from the shell without success either the use of startup.nsh is usually reserved for efi shells and such, most systems recognize bootable .efi files Rufus only offers mbr/bios for the partition table meaning it does not detect uefi in the iso

As we talked about on the telegram chan. This happens with older firmware that is unable to handle EFI stub.

To me it looks like we have CONFIG_EFI_STUB enabled: https://github.com/mocaccinoOS/desktop/blob/62ad7c54bec8b01ed86d93d34d3cc44498fd9744/packages/kernels/kernels/mocaccino/kernel/mocaccino-x86_64.config#L466, @Juesto can you provide a bit more context? what is the hw specs here? can you reproduce with modern HW?

Juesto commented 7 months ago

not all systems support direct kernel uefi boot, and most systems dont support startup.nsh at all @mudler

just efi stub does not make the iso efi compliant, providing efi shims will make this more compatible and compliant
