# Booting from SD card

#### 1. Download OS image
Go to [urveboard.com](https://urveboard.com/pi/files) and download *OS Image (Debian 11)*. Extract content of the archive. Open SD_Firmware_Tool.exe from SDDiskTool_v1.73 directory.
#### 2. Create bootable SD card
After opening  the app select device and select *SD Boot* checkbox. If you keep default value *Upgrade Firmware*, this SD card will be in upgrade mode (it will upgrade existing system). Then select update.img located in *Image* directory and click *Create*.

If any error occurs for example *Writing Loader failed!*, you should ignore that error and click *Create* again. After few minutes you should see *Creating upgrade disk ok.*

#### 3. Clear internal memory
Enter terminal of the device. Either via SSH connection or with debug UART ([Connecting to URVEPi Debug UART](https://faq.urveboard.com/books/general/page/connecting-to-urvepi-debug-uart)). Use command below to clear partition table of internal memory. 
```bash
dd if=/dev/zero of=/dev/mmcblk0 bs=512 count=1 && sync
```
**WARNING** this command is irreversible and will delete internal memory data.

#### 4. Verify
You can check if it works by using command `lsblk`. You should see root partition (/) mounted from *mmcblk1p6*.
