Understanding Ubuntu 25.04 Boot Issues

Ubuntu 25.04, also known as Lunar Lobster, is the latest long-term support (LTS) release of the popular Linux distribution. While it offers numerous improvements and new features, boot issues can still occur due to various reasons, such as:

  • Hardware compatibility issues: Incompatibility with your laptop's hardware, such as the AMD Ryzen 9 7940HS processor or Radeon 780M Graphics.
  • Kernel issues: Problems with the Linux kernel, which can cause boot failures or crashes.
  • Bootloader issues: Issues with the GRUB bootloader, which can prevent your system from booting properly.
  • File system issues: Problems with the file system, such as corruption or incorrect configuration.

Preparation

Before we dive into the troubleshooting process, make sure you have the following:

  • A working internet connection: You'll need a stable internet connection to download and install any necessary packages or updates.
  • A USB drive or CD/DVD: You'll need a USB drive or CD/DVD to create a bootable Ubuntu 25.04 installation media.
  • A basic understanding of Linux commands: While not required, having a basic understanding of Linux commands and file system navigation will make the troubleshooting process easier.

Step 1: Boot into Recovery Mode

To diagnose boot issues, you'll need to boot into recovery mode. To do this:

  1. Insert your Ubuntu 25.04 installation media: Insert the USB drive or CD/DVD containing the Ubuntu 25.04 installation media.
  2. Restart your laptop: Restart your laptop and enter the BIOS settings (usually by pressing F2, F12, or Del).
  3. Set the USB drive or CD/DVD as the first boot device: Set the USB drive or CD/DVD as the first boot device in the BIOS settings.
  4. Save and exit the BIOS settings: Save the changes and exit the BIOS settings.
  5. Boot into recovery mode: Your laptop should now boot into recovery mode.

Step 2: Run a Memory Test

A memory test can help identify issues with your laptop's RAM. To run a memory test:

  1. Open a terminal: Open a terminal by pressing Ctrl+Alt+T.
  2. Run the memtest86+ command: Run the command sudo memtest86+ to start the memory test.
  3. Wait for the test to complete: Wait for the test to complete, which can take several minutes or hours, depending on the size of your RAM.

Step 3: Run a File System Check

A file system check can help identify issues with your file system. To run a file system check:

  1. Open a terminal: Open a by pressing Ctrl+Alt+T.
  2. Run the fsck command: Run the command sudo fsck -f /dev/sda1 (replace /dev/sda1 with the actual file system device).
  3. Wait for the check to complete: Wait for the check to complete, which can take several minutes.

Step 4: Check the Bootloader

The GRUB bootloader can cause boot issues if it's not configured correctly. To check the bootloader:

  1. Open a terminal: Open a terminal by pressing Ctrl+Alt+T.
  2. Run the grub-mkconfig command: Run the command sudo grub-mkconfig to generate a new GRUB configuration file.
  3. Check the GRUB configuration file: Check the GRUB configuration file (/boot/grub/grub.cfg) to ensure it's correctly configured.

Step 5: Check the Kernel

The Linux kernel can cause boot issues if it's not configured correctly. To check the kernel:

  1. Open a terminal: Open a terminal by pressing Ctrl+Alt+T.
  2. Run the uname -r command: Run the command uname -r to check the current kernel version.
  3. Check the kernel configuration file: Check the kernel configuration file (/boot/config-$(uname -r)) to ensure it's correctly configured.
