Create Bootable USB from M1 Mac or RPi

[explosionhole]

I am trying to deploy this to a HPE Microserver Gen8. I have upgraded the CPU, and tried to use Corsair RAM but seemed to be incompatible (ordering some from MrMemory.co.uk that state compatability with my hardware).

 

In the meantime, I have moved on to creating the bootable USB drive. I have the Samsung Bar Plus 32GB (recommended from a Youtube video of fastest performing USB flash disks and using Unraid).

 

But whenever I put this in the internal USB slot, after the BIOS/POST screens, I get a couple of beeps and an error message of "non system disk" or similar. I have creating this using

• Unraid USB creator tool
• Balena Etcher
• tried following the manual install guide though some issues with this process and using either / both macOS Ventura or the M1 (needs `syslinux`, unetbootin also doesn't seem to run properly from Ventura
• copying files and executing the `make_bootable_mac` script, but this also requires `syslinux`

 

The only other device I have is a RPi, but also being ARM-based, I would expect the same issues?

 

Can I ask for any assistance please? This is usually the easiest part of these installs these days...
