Installing a 2nd NVMe Device on Debian 12: Properly Installing GRUB

In this article, we will cover the process of installing a second NVMe device on a Dell laptop running Debian 12, specifically focusing on the proper installation of GRUB. This is a crucial step to ensure that your system can boot correctly from the new device.

Preparing the System

Before we begin, it is important to ensure that your system is up to date and that you have backed up any important data. To update your system, run the following command:


sudo apt update && sudo apt upgrade

Identifying the Devices

Next, we need to identify the devices that are currently installed in your system. To do this, run the following command:


lsblk

This will display a list of all the block devices currently connected to your system. Take note of the name and size of the current NVMe device and the new 4TB device that you will be installing.

Partitioning the New Device

Now, we need to partition the new 4TB device. To do this, run the following command:


sudo fdisk /dev/nvme1n1

This will open the fdisk utility for the new device. Follow the prompts to create a new partition table, a new partition, and to set the partition type to Linux filesystem. Once you have finished, you can write the changes to the disk and exit the utility.

Formatting the New Partition

Next, we need to format the new partition. To do this, run the following command:


sudo mkfs.ext4 /dev/nvme1n1p1

This will format the new partition as an ext4 filesystem.

Mounting the New Partition

Now, we need to mount the new partition. To do this, run the following commands:


sudo mkdir /mnt/newdisk
sudo mount /dev/nvme1n1p1 /mnt/newdisk

This will create a new directory for the new disk and mount the new partition to that directory.

Installing Debian 12 on the New Device

Next, we need to install Debian 12 on the new device. To do this, run the following command:


sudo debian-installer live --media-path /mnt/newdisk/ --bootloader-installation grub-efi --efi-directory /boot/efi

This will launch the Debian installer and install Debian 12 on the new device. Be sure to select the correct disk during the installation process.

Installing GRUB on the New Device

Finally, we need to install GRUB on the new device. To do this, run the following command:


sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=Debian --recheck /dev/nvme1n1

This will install GRUB on the new device and configure it to boot from the new disk.

Update your system
Identify the current and new devices
Partition the new device
Format the new partition
Mount the new partition
Install Debian 12 on the new device
Install GRUB on the new device
