Lately Raspberry images are shipped using the xz compression, you might need to install the corresponding library to extract it.

xz --decompress 2025-05-06-raspios-bookworm-armhf-lite.img.xz
Connect the SD card to you desktop and find the name device name using
lsblk
Burn the image be sure to put the proper device name:
sudo dd if=2025-05-06-raspios-bookworm-armhf-lite.img of=/dev/mmcblk0 bs=4M conv=fsync
Config.txt
Raspberry Pi devices use a configuration file called config.txt. The GPU reads config.txt before the Arm CPU and Linux initialise. Raspberry Pi OS looks for this file in the boot partition, located at /boot/.
SSH Setup
SSH allows you to remotely access your Raspberry Pi’s terminal. One way to enable SSH:
Via SD Card (Headless Setup):
After flashing Raspberry Pi OS onto the SD card, insert it into your computer.
In the root of the boot partition, create an empty file named
ssh(no extension). This enables SSH on first boot
Connection
ssh pi@raspberrypi.local
