Are you saying that this command (the one right above) will clone the whole disc, and the job is done? Probably not. When I run "dd --help" on the system i want to clone, there is no information about the switch "id" you use in the command. > > Viz: > > > df -h | grep ^/dev/ Running that command on my system gives: raspberrypi@raspberrypi:~ $ df -h | grep ^/dev/ /dev/sda2 234G 19G 203G 9% / /dev/sda1 511M 76M 436M 15% /boot/firmware For /dev/sda1 it says "firmware", so it probably should/can not be copied, and is permanent on the raspi5-system > /dev/root        15G  1.5G   13G  11% / > /dev/mmcblk0p1  255M   51M  205M  20% /boot > > These are the TWO partitions on a bootable PI device > In /boot which is DOS style formatted will be instructions on how to > boot the main system > > In the main bootable system there will be the fstab file which needs to > tally with the partition ids. > > more /etc/fstab: > > proc            /proc           proc    defaults          0       0 > PARTUUID=b8c9fbb7-01  /boot           vfat    defaults          0       2 > PARTUUID=b8c9fbb7-02  /               ext4    defaults,noatime  0       1 > > In the BOOT partition is this file >  more *.txt > :::::::::::::: > cmdline.txt > :::::::::::::: > console=serial0,115200 console=tty1 root=PARTUUID=b8c9fbb7-02 > rootfstype=ext4 fs > ck.repair=yes rootwait modules-load=dwc2,g_ether > > Unless the bootloader finds that partition ID, it will *not load Linux* > > AIUI the boot sequence is this: > > Look for a DOS style VFAT partition on SD card, then USB, then NVME. > > Look for a file named 'cmdline.txt' parse the root partition ID  and > attempt to load a linux image from the boot  partition and have the > kernel image mount the aforementioned PARTUUID as root partition. > > If the PARTUUIDs don't match, the boot sequence hangs > > So it is important to have the same PARTUUID in /boot/cmdline.txt, and > in /etc/fstab, and in the partition label on the boot partition > > The easy way to do this is not to clone the partitions, but the RAW DISK > > >> And following drucks first suggestion I should run these 2 commands: >> 1: dd if=/dev/sda2 of=/dev/nvme0n1 bs=1M status=progress >> and >> 2: dd if=/dev/sda1 of=/dev/nvme0n1 bs=1M status=progress >> >> replacing the name of the NVME to what I see when it is installed on >> the raspi. >> >> Best regards, and thank you for the help. > > That wont work, but you wont destroy anything by trying So I will not try :-) I think I should not take any more of your time for this project. Using a PC and a windows program (Macrium Reflect) to clone the disc will take maybe 30 minutes. Learning the ins and outs of how it should be done in raspi-os can take 14 days for a windows-addict:-) Best regards, and thank you for the help so far. -- Jesper
