Hi, i proposed for booting from the now reluctant USB stick: > > grub> linux /install.amd/vmlinuz vga=788 --- quiet > > grub> initrd /install.amd/gtk/initrd.gz > > grub> boot

The internet shows such starts with first command "set root". https://superuser.com/questions/1237684/how-to-boot-from-grub-shell https://askubuntu.com/questions/883992/stuck-at-grub-command-line So perhaps: grub> set root=(hd0) grub> linux /install.amd/vmlinuz vga=788 --- quiet grub> initrd /install.amd/gtk/initrd.gz grub> boot We could need some more experienced GRUB operator for finding the part of the boot process wich fails. It looks like GRUB is found and started. But then somethig goes wrong. For now we know that the various grub.cfg are visible in the stick's EFI partition (hd0,msdos2) and in the stick's ISO filesystem (hd0). If the kernel can be started and does not abort to fall back to GRUB then i am out of guesses about how GRUB fails to find and execute the grub.cfg files. Have a nice day :) Thomas
