Hello Chris!

23 Jan 25 22:12, you wrote to all:

Maybe this is useful

https://aroundmyroom.com/2018/07/28/update-boot-from-usb-with-hp-microserver-
gen8-and-openmediavault/

and gives you hints

I own some HP Gen8 Microservers where you cannot boot (depends on how you want
to use the HDD's) from the ODD port, but you can use it to have a disk
connected to it for further use

So the trick is to boot from your SD and than tell Grub that it has to use that
device for the rest
so the USB disk (in my instance) was only getting start and than go further to
the SATA

But it should not matter if that is SD or USB whatever..

If you start chatgpt.com  ..
and ask a question like

how to start from an SD card (initial boot) on a raspberry pi and than the rest
through grub starting to the USB ?

you get also an answer you might be able to use
