Libefivar1/stable,now 37-6 arm64 īUT note that all this will not work on real hardware. I see that following is installed (by myself, not installer):Įfibootmgr/stable,now 17-1 arm64 In a VM one can easily boot by direct kernel+initrd load and then install GRUB and EFI in running system. AFAIK it should be:Īt my Debian install, grub.cfg is not there, but it boots, it could simple be that it fails to load debian and then tries EFI/BOOT/bootaa64.efi, which I manually copied from EFI/debian/grubaa64.efi That is the file UEFI firmware loads if nothing else is there.īut for every OS installed, there be a separated directory with the bootfiles for that OS. Then besides the files from, there should be a file: At leatst for RPi4 with new enough EEPROM. The whole 'boot architecture' for ARM platforms is not so mature/robust/etc as for PC's.īut on the first FAT (make it FAT16), type can be 0C or EF (MBR) / 0700 or EF00 (GPT). I should have manually installed a flavor of GRUB first. All went smooth until I rebooted for the first time. I have seen this for both Debian arm7 (32-bit) and aarch64 where I did an install in a virtual machine environment with QEMU/libvirt. I know the warnings at the end of installation that all went fine, BUT no bootloader has been installed. This method of installing via the network has the problem that the (Debian) installer is not sure on what to install as bootmethod/bootprogram. Has anyone got a PXE install of Debian to a Pi's empty USB stick working? Any tips would be gratefully received! I don't know what to do on the ESP so that GRUB starts. However, GRUB is not loaded so Debian never starts. I did this manually on that resultant USB stick and the Pi now boots, loading the UEFI firmware from the USB stick. Akeo's guide ( viewtopic.php?t=282839) details extracting the UEFI firmware zip onto the ESP. The installation runs without error but the resultant USB stick isn't bootable. PXE via UEFI ( ) works perfectly and GRUB starts a Debian 11 arm64 netboot install. I know the Pi has network boot functionality that behaves like PXE (. I've found lots of guides on 'diskless' installs, where the OS is running from the network, but I'd like to install an OS, from the network, on an empty USB stick. I would like to do something similar for a Pi 4. I have a simple PXE setup for x86/圆4 PCs to install Debian.
