Installing GRUB for a New Custom-Created Linux OS (Yocto) on Partitioned sda

Introduction

In this article, we will guide you through the process of installing a new bootable Linux OS on partitioned sda, specifically a custom-created Linux OS made with Yocto Project. The prerequisite for this task is that you have already partitioned your sda using your preferred method.

Installing a New Bootable Linux OS on Partitioned sda

After partitioning your sda, the next step is to install the new Linux OS. In this example, we will use the Yocto Project to create a custom Linux OS. Here are the general steps:

1. Create a Yocto Project BSP (Board Support Package)
2. Configure the BSP for your target hardware
3. Build the Linux image using the BitBake tool
4. Write the image to a bootable medium, such as a USB drive or SD card
5. Install the Linux OS on the partitioned sda

1. Create a Yocto Project BSP

To create a Yocto Project BSP, follow these steps:

1. Install the Yocto Project prerequisites, such as Git, Python, and the Yocto Project core tools.
2. Clone the Yocto Project source code from the official Git repository.
3. Create a new BSP directory and initialize it with the Yocto Project tools.
4. Configure the BSP for your target hardware by creating a machine configuration file.

2. Configure the BSP for Your Target Hardware

In the machine configuration file, you will configure the BSP for your target hardware. This includes:

• Defining the hardware architecture
• Setting up the kernel and bootloader
• Configuring the file system

3. Build the Linux Image Using the BitBake Tool

Once you have configured the BSP, you can build the Linux image using the BitBake tool. This process can take some time, depending on the complexity of your BSP and the speed of your hardware.

To build the image, run the following command:

4. Write the Image to a Bootable Medium

After the image has been built, you need to write it to a bootable medium, such as a USB drive or SD card. This can be done using the dd command:

5. Install the Linux OS on the Partitioned sda

Before installing the Linux OS on the partitioned sda, make sure that the partition table is correctly set up. You can use a tool like GParted to check this.

To install the Linux OS, follow these steps:

1. Boot from the bootable medium
2. Choose the installation language and select the installation type
3. Partition the sda using the available partitions
4. Select the installed Linux image and choose the partitions for the root file system, bootloader, and other partitions
5. Confirm the installation settings and start the installation process

In this article, we have covered the process of installing a new bootable Linux OS on partitioned sda using the Yocto Project. We have gone through the steps of creating a Yocto Project BSP, configuring it for your target hardware, building the Linux image, writing it to a bootable medium, and installing it on the partitioned sda.
