Topic: Linux Ubuntu Boot Errors | Status: Updated
What is this error?
Error 15: File not found is a common boot error in Linux Ubuntu, indicating that the bootloader cannot locate a required file or operating system configuration during the startup process. This error often occurs due to an incorrect path in the boot configuration or a missing kernel/initrd image.
How to Fix It
- Boot into Live USB: Create a bootable USB drive with Ubuntu and boot your computer from it.
- Open Terminal: Once in the live environment, open the Terminal by pressing
Ctrl + Alt + T.
- Locate your root partition: Use the command
sudo fdisk -l to list all partitions and identify your Linux installation's primary partition (like /dev/sda1).
- Mount your root partition: Run
sudo mount /dev/sda1 /mnt, replacing /dev/sda1 with your identified partition.
- Access boot directory: Navigate to the boot directory by executing
cd /mnt/boot.
- Check for files: List available files by typing
ls. Ensure that the necessary files such as vmlinuz and initrd.img exist.
- Edit GRUB configuration: If files are missing or paths are incorrect, edit the GRUB configuration using
sudo nano /etc/default/grub. Correct any invalid paths.
- Update GRUB: After making changes, update GRUB using the command
sudo update-grub.
- Reboot the system: Exit the terminal, unmount the partition with
sudo umount /mnt, and reboot your computer with sudo reboot.
