Select the icon and the installer should start. A nice icon with the USB logo should be shown in the boot menu. Insert the prepared USB drive to the MacBook and turn it on while pressing the Option (Alt) key. If loadfont /boot/grub/fonts/unicode.pf2 thenĬopy installer and ISO image to the USB driveĮxtract the kernel and initrd from the ISO and copy them and the netboot ISO image itself to the USB stick: If you need to debug the GRUB settings interactively, remove the last line (boot). The config below sets the graphics mode and font on the console to something the installer can use, loads the kernel and initrd into memory and boots. Make a grub.cfg file in /mnt/usb/boot/grub/grub.cfg. Grub-install -target=i386-efi -efi-directory=/mnt/usb -boot-directory=/mnt/usb/boot -bootloader-id=boot -removable

If your spare drive has another partition type or file system, use fdisk to make a 'W95 FAT32' MBR partition (hex partition code 0x0b) and mkfs.vfat to clear the partition and make a new FAT32 filesystem. Installing GRUB and copying the installer files does not destroy the data on the drive, but just to be sure, take backups. If you already have a USB drive with a FAT32 file system and about 50 MB free space, you're set. Download netboot ISO image from your Debian mirror, e.g.Install grub-efi-ia32-bin, 7zip and dosfstoolsĪpt-get install grub-efi-ia32-bin p7zip-full dosfstools.you don't need another Mac running linux). The jessie netboot requires less than 64 MB, so any old USB stick will do.Ī computer already running Debian jessie, any architecture will do (i.e. MacBook2,1 is also able to run 64-bit linux (amd64 architecture in Debian), but this guide will use the i386 version.Ī USB drive with enough space for the ISO image of your choice.

This guide shows how to prepare a 32-bit EFI bootable USB drive which has the Debian installer and an i386 installation ISO image of your choice (we'll use the netboot image mini.iso in the examples) using another Debian (Jessie) system to prepare the USB drive. The UEFI bootloader in these disk images is the 64-bit version, which does not boot even in the 64-bit ?MacBook2,1 because the Apple firmware expects 32-bit EFI binaries. The firmware interface in both models is however 32-bit UEFI.ĭebian installer releases for Jessie have UEFI support only in the amd64 ISO images. NetBoot is a derived work from the Bootstrap Protocol (BOOTP), and is similar in concept to the Preboot Execution Environment. New World ROM ) to boot from a network, rather than a local hard disk or optical disc drive. The early Intel-based white MacBooks from 20 came either with the 32-bit Intel Core Duo processor (MacBook1,1) or the 64-bit Intel Core 2 Duo (MacBook2,1). NetBoot was a technology from Apple which enabled Macs with capable firmware (i.e. Here's how to install Debian (jessie) on 32-bit UEFI based MacBooks (MacBook1,1 and Macbook2,1) from 2006-2007 (only tested on MacBook2,1 but MacBook1,1 should work as well).
