The 'no such partition' error, also known as Grub rescue, occurs when the bootloader is unable to find the Linux partition. This issue affects users who have deleted their Linux partition from Windows without properly repairing the Master Boot Record (MBR). The frustration lies in the fact that this error can be caused by a simple mistake, and the solution involves using a small utility that can be easily downloaded and run from an USB drive.

Fortunately, there are several methods to resolve this issue without needing a Windows boot CD or a CD drive. In this guide, we will walk you through two primary fix methods: using a small Linux live CD and utilizing a custom rescue tool.

🛑 Root Causes of the Error

  • The first main reason why the 'no such partition' error occurs is when the MBR becomes corrupted due to deleting the Linux partition from Windows. This can happen if the user forgets to repair the MBR or doesn't have the necessary tools to do so.
  • An alternative reason for this error is that the Grub bootloader has become outdated or corrupted, preventing it from detecting the correct partition.

🚀 How to Resolve This Issue

Using a Small Linux Live CD

  1. Step 1: Download a small Linux live CD image (such as Ubuntu Rescue Mode) and create a bootable USB drive using a tool like Etcher or Rufus. Make sure to select the correct architecture (32-bit or 64-bit) that matches your system.
  2. Step 2: Insert the USB drive into your computer and restart it. Select the USB drive as the first boot device, usually by pressing F12, F2, or Del during startup. The live CD will boot from the USB drive, allowing you to access a command-line interface.
  3. Step 3: Once booted, type 'sudo fsck -t ext4' (or the file system type of your Linux partition) to scan for and repair any damaged file systems. If successful, type 'sudo grub-install /dev/sda' (replace '/dev/sda' with the actual device name of your disk).

Using a Custom Rescue Tool

  1. Step 1: Download a small Linux-based rescue tool such as GrubRescue or UBCD-Live. These tools are designed to provide a minimal environment for repairing the MBR and Grub bootloader.
  2. Step 2: Insert the USB drive containing the rescue tool into your computer and restart it. Select the USB drive as the first boot device, usually by pressing F12, F2, or Del during startup. The rescue tool will boot from the USB drive, presenting a menu with various options.
  3. Step 3: Select the option to repair the MBR and Grub bootloader. The rescue tool will guide you through the process of repairing the file systems and reinstalling the Grub bootloader.

💡 Conclusion

In conclusion, the 'no such partition' error can be resolved by using a small Linux live CD or a custom rescue tool. By following these steps, users can safely repair their MBR and Grub bootloader, ensuring that their system boots correctly again.
