I have a Pi 5 16gb that previously had Ubuntu installed and was booting from 1 of 2 NVME drives (nvme0n1). I want to switch to Debian for arm64. I changed the boot order and booted into Pi OS from an SD card. I then downloaded the Debian ARM ISO and opened pi imager (showing version 1.9.4) Now I am having 2 problems:
Pi Imager keeps indicating a newer version is available and it takes me to a link that provides a shell command to update pi imager. When I run it nothing is installed and it indicates I am already on the latest version.
2. When I attempt to flash the ssd it gives a message that the drive is missing an MBR signature. When I run LSBLK the drive both nvme's appear. There is a file named nvme0n1 in my /dev folder but when enter "sudo umount dev/nvme0n1", I get the following:
umount: dev/nvme0n1: no mount point specified
How do I reformat, initialize and mount the nvme? I attempted to write to the second nvme but get the same message. It was never bootable. Any suggestions would be greatly appreciated.
