 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..

This is completely inappropriate for a Raspberry Pi, which does not boot like a PC using grub.

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

More bad advice.
See later in this thread for the actual answer.
