Expected behavior

When I try to make a bootable USB with ubuntu-24.10-desktop-amd64.iso then everything works.

I tried also the linuxmint-22-xfce-64bit.iso - same result. The image is not bootable.

I tried to create bootable USBs under Ubuntu using Startup Disk Creator with same results.

I also tried to use 3 different USB keys and I also tried to do this under Guix running on a different Hardware.

The results were everytime the same. Your iso images are broken. The ubuntu-24.10-desktop-amd64.iso works.

Cheers Bost

Well, I just found out that when I change the Boot Option Priorities, setting Boot Option #1 from UEFI USB Key to UEFI USB CD/DVD:UEFI SanDisk, the GRUB menu appears - yay... almost.

In the GRUB menu, when I select Start Linux Mint 22 Cinnamon 64, my laptop freezes. I need to choose Start Linux Mint 22 Cinnamon 64 (compatibility mode) instead.

None of this is required to boot the aforementioned ubuntu-24.10-desktop-amd64.iso.
