What you're asking for here won't work; arm64 devices don't/can't use the embedding MBR/gap style of GRUB installation - that's x86 only. Instead, what you need is to do an EFI installation but with a couple of extra options chosen. Run "dpkg-reconfigure -plow grub-efi-arm64" and say: * "yes" to "Force extra installation to the EFI removable media path?" * "no" to "Update NVRAM variables to automatically boot into Debian?" and and you should be fine from now on. -- Steve McIntyre, Cambridge, UK. st...@einval.com There's no sensation to compare with this Suspended animation, A state of bliss
