Troubleshooting • RPI5 bon't boot

Hey.
I installed Ubuntu 24.04 on an USB 3.0 SATA disk and work fine. I bought a NVMe adapter and memory and installed Raspberry Pi OS. I find with: the BOOT_ORDER=0xf461 and change to 0xf164

The, when I reboot, the Pi just blink around 9 times, a little pause then 9 times.

I downloaded with Pi-Imager: Bootloader (Pi 5 family), booth "SD Card Boot" and "NVMe/USB Boot and run. Boot get a Green screen and a rapidly blinking.

When I then try to bootfrom SD, NVMe or USB, the PI start blingnking 9 times little pause and the 9 again forever.

The boot-loader seems to work (green screen and rapidly blinking green led, so I don't know why it is not booting

For SD-boot, do I need to use the same card, to have a OS on? It think it does not matter , but It is desribde in the README.txt o the Bootloader config SD-card. Have an 64GB ard AND a 2GB card, and for the bootloader config the max is 32GB.

/Cheers and I am greatfull for all help in right direction.
