When installing Linux, one common issue that users encounter is the message stating that the "boot loader isn't located in the partition selected." This can lead to confusion and frustration, especially for those new to Linux. In this article, we'll clarify this problem, analyze its causes, and provide practical solutions to ensure a smooth Linux installation experience.
Problem Scenario
During a typical Linux installation, users select a partition where they want to install the operating system. However, if the installer is unable to locate the boot loader in the selected partition, it can lead to an unsuccessful boot process. Here's a snippet of the original problem:
Error: Boot loader isn't located in the partition selected during Linux installation.
Understanding the Boot Loader
The boot loader is a critical component of the operating system. It is the first software that runs when a computer starts, and it is responsible for loading the operating system into memory. In the context of Linux, popular boot loaders include GRUB (GRand Unified Bootloader) and LILO (Linux Loader).
Causes of the Issue
-
Incorrect Partition Selection: One of the most common reasons for this issue is the user selecting a partition that doesn't support boot loaders or is not designated for such use (e.g., a data partition).
-
Partition Type: The selected partition must be set as active or bootable. If it's not, the boot loader won't be able to install properly.
-
UEFI vs. BIOS: If you're using UEFI firmware and select a Legacy mode during installation, or vice versa, this mismatch can prevent the boot loader from being installed correctly.
-
Disk Partitioning Scheme: If you're using an unsupported partitioning scheme or your disk is formatted in a way that is incompatible with the installer, it may lead to this error.
-
Corrupted Installation Media: Sometimes, the installation media can be corrupted, leading to installation errors including issues with the boot loader.
Solutions
To resolve this issue, here are some practical steps:
1. Verify Partition Selection
Double-check that you are selecting the correct partition for the installation. Ensure that the partition is formatted as ext4 or another Linux-compatible filesystem and is marked as bootable.
2. Use GParted
If you're unsure about the partitioning, consider using GParted to manage your partitions before the installation. GParted allows you to check the partition status, format partitions, and set bootable flags easily.
3. Boot Mode Consistency
Make sure that your boot mode (UEFI or Legacy BIOS) matches the type of installation you are performing. For example, if your hardware supports UEFI, you should use UEFI mode for the installation.
4. Recreate Installation Media
If you suspect that your installation media may be corrupted, recreate it using a reliable tool like Rufus or Balena Etcher, and then attempt the installation again.
5. Use the Rescue Mode
If you encounter this issue post-installation, consider using a Linux live CD to boot into a rescue mode and reinstall the boot loader manually. You can do this by running the following command from the live environment:
sudo grub-install /dev/sda
sudo update-grub
Replace /dev/sda with your actual disk where the Linux operating system is installed.

Conclusion
Understanding the boot loader and its importance is crucial when installing Linux. Encountering the error stating that the boot loader isn't located in the selected partition can be frustrating, but by verifying partition selections, ensuring boot mode consistency, and utilizing appropriate tools, you can overcome this hurdle. Always remember to back up your data before making changes to partitions or the boot loader to avoid data loss.
By following the above guidelines, you will enhance your Linux installation experience and avoid common pitfalls associated with boot loader issues. If you continue to experience difficulties, consult online forums and community resources for assistance.
