I have my Pi5 booting from an NVMe drive on a Pimoroni NVMe base and the boot order is set to boot fro NVMe first. I wanted to try out some new software and was going to use an fresh OS install on a micro SD card, to try it out before committing it to my main system. However if I change the boot order to **B1. Boot from SD card if available, otherwise boot from NVMe**. It will continue to boot from the NVMe.  
Is there another way to change the boot order?  
I can boot from the SD card if the NVMe is detached, however I don’t want to be constantly detaching and attaching the NVMe drive, to achieve the desired result.

Any advice would be gratefully received.

- First, check your current boot order setting.
  - $ rpi-eeprom-config

- If you see BOOT\_ORDER=0xf146, the boot order has not been changed.
- Change the boot order.
  - Let say you are booted to drive X (SD, NVMe, or USB)
  - $ sudo raspi-config
  - Select Advanced Options, then Boot Order, then B1.
  - This writes the change to a temporary file stored on drive X. But the change is not made to the eeprom until you reboot drive X.
  - You will be asked if you want to reboot. Select Yes.

- Now that you have rebooted, try $ rpi-eeprom-config. You should see BOOT\_ORDER=0xf461.
- Shutdown.
- Insert a SD card containing a RPi OS image.
- Reboot

Thanks for the input.

After a bit more searching, I found the problem, when I cloned the SD card from the NVMe card I did not let it assign new UUID’s to the partitions.  
So I recloned the NVMe drive to the SD card with new partition UUIDs, then booted into NVMe and changed the boot order back to **B1. Boot from SD card if available, otherwise boot from NVMe** and rebooted with the SD card in and all went as expected.
