If you’re encountering the dreaded “No init found. Try passing init=bootarg” error when trying to boot your Ubuntu system, don’t panic. This error is indicative of an issue with the system’s initiation process, and there are several potential causes and solutions to explore.

Understanding the Error

The error message suggests that the Linux kernel is unable to find the initialization (init) process, which is essential for the proper functioning of the operating system. This can happen for various reasons, ranging from corrupted files to misconfigured boot parameters.

Possible Causes

Filesystem Corruption: If the filesystem containing the init process is corrupted, the system may fail to locate it during boot.

Incorrect Boot Parameters: The boot parameters passed to the kernel may be incorrect or missing, leading to the failure to locate the init process.

Boot Loader Configuration Issues: Problems with the configuration of the bootloader, such as GRUB, can also contribute to this error.

Step-by-Step Solutions

Boot from Live USB

Create a Ubuntu Live USB and boot from it.

Open a terminal and access the root partition of your installed Ubuntu system.

Check Filesystem

Run a filesystem check on the root partition using the fsck command.

sudo fsck /dev/sdXY

Replace /dev/sdXY with the appropriate partition identifier for your system.

Verify Boot Parameters

Check and correct the boot parameters in the GRUB configuration.

sudo nano /etc/default/grub

Ensure that the GRUB_CMDLINE_LINUX parameter includes the correct root partition and other necessary options.

Reinstall GRUB

Reinstall the GRUB bootloader to fix any configuration issues.

sudo grub-install /dev/sdX
sudo update-grub

Replace /dev/sdX with the device identifier for your hard drive.

Restore init Process

If the init process is missing or corrupted, reinstall the init package.

sudo apt-get install –reinstall init

Kernel Upgrade

Consider upgrading the Linux kernel to a newer version.

sudo apt-get install –install-recommends linux-generic

Conclusion

The “No init found” error in Ubuntu can be a frustrating experience, but with systematic troubleshooting, it can often be resolved. By following the steps outlined above, you can address the potential causes of the issue and get your Ubuntu system back to a healthy boot state.

Remember to proceed with caution, especially when dealing with filesystem-related operations, to avoid further data loss. If the problem persists after trying these solutions, seeking assistance from the Ubuntu community forums or other support channels may be beneficial.
