Old MacBook does not boot from USB

[hijjj]

Hi -

I have an old macbook1,1 - which i would like to keep using as debian machine. at the moment i just do not get it to boot from a USB drive. I had a look at https://wiki.debian.org/InstallingDebia ... acBook/2-1 and downloaded the mini.iso.

I formated the USB drive on a Mac:
sudo diskutil partitionDisk /dev/disk2 GPT FAT32 New 0b

diskutil list shows
/dev/disk2 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: FDisk_partition_scheme *1.0 GB disk2
1: DOS_FAT_12 Firmware 6.3 MB disk2s2

I used balena Etcher to copy the mini.iso onto the drive

When I boot my macbook pressing "alt" it boots straight into MacOs.

When I boot holding down "D" or "C" the EFI bootloader appears but it only shows the mac hd - while the USB drive is blinking and seems to be recognised ...

Any suggestions what I am missing here or if more information needs to provided.

Cheers!

You don't need to format the USB drive. Just copy the iso to the root of the drive.

Code: Select all

dd if=mini.iso of=/dev/disk2

^ Don't forget to flush the buffers!

I prefer cp:

Code: Select all

# cp mini.iso /dev/disk2 ; sync

Easier to remember and also (slightly) quicker
