rEFIt was still be able to boot OSX, even when I messed up the grub install options. When I bricked the Mini, I was running on Apple's boot loader. Please comment if you find a shorter sequence.Īsides from getting Ubuntu to boot, rEFIt is handy because it rescues you in case something blows up. When the rEFInd screen comes up, select the fallback bootloader (boot manager I dont remember) on the flash drive you plugged in. Go and plug the flash drive into your Mac Mini, and restart it. I know that the last steps look like black magic (pulled out of my behind). So, we need this file to let the Mac Mini do a 32 bit EFI boot of the 64 bit Ubuntu ISO. It will offer to update the MBR to reflect the EFI partition table. Upon rebooting, go to Partitioning Tool (second icon in the bottom row) in rEFIt.This is necessary so that Grub installs in the right place. The post includes a tutorial for installing Ubuntu on M1 Macs, and theres a Github repo (corellium/linux-m1) that you can download the kernel from. On the last install screen, click Advanced, and replace (hd0) with (hd0,2).Choose manual partitioning, delete the big FAT32 partition that Boot Camp created (leave the EFI partition alone though), and create the root and swap partitions in the free space. Don't worry if you've never seen it before. Reboot and insert your Ubuntu 8.04 disc.Optionally, switch the boot default to Linux: open /efi/refit/nf in TextEdit, and uncomment the line saying #legacyfirst (at the very bottom).Make rEFIt take over the boot process (it should do that by itself but that doesn't work for me):.Quit Boot Camp when it offers to start the Windows installation. It is very easy to install since Ubuntu 18.04. Swap: Im using 18.04 because no swap disk is necessary. rEFInd (Download the Binary Zip), dont install yet. Start up Boot Camp, and resize your OSX partition. External Destination Drive (where your Ubuntu installation will live) Install Drive (USB stick etc) unetbootin.Use the Leopard (Desktop or Server) install disc to re-partition the disk to 1 partition, then install Leopard.One day later, I figured out a (small) sequence of steps that yields a working dual-boot of Leopard and Ubuntu 8.04. I promptly got my Mini to not boot by trying to install it using the same procedure I used for 7.10. Update: please read my new post if you want to install Ubuntu 8.10 or 9.04.
