Ubuntu 14

When you’re using Ubuntu, you may occasionally run into some issues. One error that users often encounter is “file ‘/grub/i386-pc/normal.mod’ not found”. This error can prevent your system from booting up properly, but don’t worry – it can be fixed. In this article, we’ll walk you through the steps to resolve this issue.

Quick Answer

To fix the "file ‘/grub/i386-pc/normal.mod’ not found" error in Ubuntu, you need to locate the normal.mod file, set the correct values for the root and prefix variables, and load and run the normal module.

Understanding the Error

Before we delve into the solution, it’s important to understand what this error means. The ‘grub’ in the error message refers to the GRUB (GRand Unified Bootloader) – a bootloader package developed to support multiple operating systems and allow a user to select among them during boot-up. The ‘normal.mod’ is a GRUB module that is necessary for the system to boot up properly. If this file is not found, it can result in the error message.

Locating the normal.mod File

The first step in resolving this issue is to locate the normal.mod file. Here’s how you can do it:

  1. Boot your system. When you see the grub rescue> prompt, type the following commands:
grub rescue> ls
grub rescue> ls (hd0,msdos1)/
grub rescue> ls (hd0,msdos1)/boot/grub/i386-pc/normal.mod

The ls command lists the contents of a directory. In this case, you’re looking for the normal.mod file in the (hd0,msdos1) partition. If the file is found, note down the partition.

Searching for the normal.mod File

If the normal.mod file is not found in the initial location, you can search for it using the search.file command. Here’s how:

grub rescue> search.file /i386-pc/normal.mod
grub rescue> search.file /grub/i386-pc/normal.mod
grub rescue> search.file /boot/grub/i386-pc/normal.mod

The search.file command searches for the specified file. If the command returns a result, note down the partition where the file is located.

Setting the Correct Values for root and prefix

Once you’ve identified the partition where the normal.mod file is located, you need to set the correct values for the root and prefix variables. Here’s how:

grub rescue> set root=(hd0,msdos1)
grub rescue> set prefix=(hd0,msdos1)/boot/grub

The set command is used to set the value of a variable. In this case, you’re setting the root and prefix variables to the correct partition.

Loading and Running the normal Module

After setting the correct values for root and prefix, you can try loading and running the normal module. Here’s how:

grub rescue> insmod normal
grub rescue> normal

The insmod command is used to load a module into the kernel, and the normal command is used to start the normal shell.

If everything goes well, the system should boot normally. If not, you may need to try alternative solutions or consider reinstalling the operating system.

Conclusion

Fixing the “file ‘/grub/i386-pc/normal.mod’ not found” error in Ubuntu involves locating the normal.mod file, setting the correct values for the root and prefix variables, and loading and running the normal module. While these steps can be a bit technical, they are crucial for resolving this error and ensuring your system boots up properly.
