No you can't, when Apple silicon Mac with M1 cannot load Recovery options. It shows exclamation mark and url to go for support, where you learn that it would boot only with the help of 'another Mac'
The comment I was replying to was about booting from an SD card. There’s no reason to think that would work differently from the USB booting option that already exists.
>here’s no reason to think that would work differently from the USB booting
Inability to boot my previous Mac from sd-card could be that reason? Or am I missing something? Because it was not possible to boot from sd-card last time I've tried.
What I’m saying is that there’s already the ability to boot from removable media (USB). If your problem with the existing solution is that it has some limitations, then it doesn’t make sense to demand SD boot, because it would probably have exactly the same limitations.
That procedure will create a boot partition on the built in drive and use it to jump to the partition on the TB3 drive - because the built-in bootloader doesn't have support for loading or even enumerating drives other than the built-in one.
