Booting installation iso from usb disk results in boot error

[kidharb]

I have a non legacy boot laptop and a legacy boot laptop. I have written t2-24.5-x86-64-base-wayland-glibc-gcc-nocona.iso to the USB flash disk via d bs=4M if=./t2-24.5-x86-64-base-wayland-glibc-gcc-nocona.iso of=/dev/sda status=progress oflag=sync

The USB disk boots on the legacy boot laptop but does not boot on the non-legacy boot laptop.

On the non legacy boot laptop I get the following Grub error /boot/grub/x86_64-efi/normal.mod not found

If I run isohybrid on the iso file before writing to the flash disk, I get the following error

isohybrid --uefi t2-24.5-x86-64-base-wayland-glibc-gcc-nocona.iso                                      
isohybrid: t2-24.5-x86-64-base-wayland-glibc-gcc-nocona.iso: boot loader does not have an isolinux.bin hybrid signature. Note that isolinux-debug.bin does not support hybrid booting

So isohybrid cannot convert the iso into hybrid mode

Am I using the correct iso or is there a step that I am missing?

is windows secure boot off on the uefi

[kidharb]

Yes it is

[coolluke1992]

unless you have a real reason for uefi you could get away with legacy bios mode if its got it could be called CSM i think unless its a real problem with those isos but they work with QEMU EFI vms so unless rene has a dell to test uefi with im not sure what else it could be

[kidharb]

I wish I could I enable legacy bios mode, but I cannot :-(

I will work on creating a "hybrid" ISO image. Can I contribute to the project here or on https://svn.exactcode.de?
