Identifying the SD Card mounting point to write the Raspberry Pi system image. Start by opening a command line as Root, and type the command
lsblk to get existing list of available drive(s).
The usage of this information can damage your current system. Please use care and make sure to follow recommendations, advice and also your own analysis before proceeding. I will not take responsibility for any damage you may cause to your system following these instructions.
arnaud@VBM-Testing: ~$ sudo su [sudo] password for arnaud: root@VBM-Testing:/home/arnaud# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 60G 0 disk -sda1 8:1 0 60G 0 part / sr0 11:0 1 1024M 0 rom
Then connect the SD Card by plugging it into the SD Card reader and type the same command again,
lsblk. We will now get the SD Card information by comparison.
root@VBM-Testing:/home/arnaud# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 60G 0 disk -sda1 8:1 0 60G 0 part / sdb 8:16 1 15.1G 0 disk -sdb1 8:17 1 15.1G 0 part /media/arnaud/SD16GB sr0 11:0 1 1024M 0 rom
Here we can see a new device in the list, name sdb, with 1 partition on it: sdb1. That is a SD Card as it is the only device we connected in between. We can also see the partition is mounted. We need to un-mount them with
root@VBM-Testing:/home/arnaud# umount /media/arnaud/SD16GB
Note 1: The SD card was already imaged with a Raspbian image, that I wasn’t using anymore, you may see only 1 partition on the SD Card that have the size of the entire SD Card.
Note 2: Raspbian project has been renamed “Raspberry Pi OS” but it is none the less the same thing. As running the command on a “Raspberry Pi OS”
cat /etc/os-release provide the following results and Raspbian naming is still all around. Don’t get confused by that in the near future. It is also very possible that changes later as well.
cat /etc/os-release PRETTY_NAME="Raspbian GNU/Linux 10 (buster)" NAME="Raspbian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=raspbian ID_LIKE=debian HOME_URL="http://www.raspbian.org/" SUPPORT_URL="http://www.raspbian.org/RaspbianForums" BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"
We need to extract it from the zip file we downloaded before we can write it to the SD card, for that we will use
unzip command. The file will be extracted in the current folder with command below (eg.
/home/arnaud/ in this example).
root@VBM-Testing:/home/arnaud# unzip Downloads/2019-04-08-raspbian-stretch-lite.zip
We can now write the Raspberry Pi image to the SD Card using the command
dd. This command will copy 4MB
bs=4M at the time, from the source image
if=2019-04-08-raspbian-stretch-lite.img to the SD Card
of=/dev/sd. It will done synchronously with
conv=fsync (meaning it will finish to write on the SD Card before reading the next 4MB of the image source) and
status=progress will also display progression of the entire process.
root@VBM-Testing:/home/arnaud# dd bs=4M if=2019-04-08-raspbian-stretch-lite.img of=/dev/sdb conv=fsync status=progress
Progression will look like this:
448790528 bytes (449 MB, 428 MiB) copied, 14 s, 31.1MB/s
Note 3: Soon I will add a new article with my preferred 1st steps after getting the SD Card ready, those are definitely options but as mentioned my preferred steps before booting the OS for the 1st time. That article will be linked about here at the end of this article (just be patient for that one if you land here before I write it).
Once copy is completed it will return to regular prompt. The SD Card may mount automatically again, dismount it in this case, and remove it from the computer. We are now ready to boot from it using the Raspberry Pi.
