Inspecting the Current State of Your Partitions
The first step towards resolving the ‘Error No Such Partition. Grub Rescue’ issue is inspecting the current state of your partitions. If you have been partitioning your hard drive or trying to install a new operating system, it is possible that something went awry with the process. The Grub (Grand Unified Bootloader) rescue prompt appears when the Grub can’t find the partition from which it’s supposed to boot. To start, you need to list the partitions available on your hard drive by typing the command ls at the Grub rescue prompt. This will show all the partitions present in your system.
Next, you need to identify the root partition where your Grub was installed. You can do this by running a series of ls (hdX,Y) commands, replacing X and Y with the hard drive and partition numbers, respectively, until you find the partition with /boot/grub. Once you’ve identified your root partition, you need to set the root and prefix settings in Grub accordingly.
The final step in this process is to attempt to boot from the detected partition. You can do this by running the insmod normal and normal commands. If successful, this will take you out of the Grub rescue prompt and into the usual Grub boot menu, allowing you to boot your operating system normally.
However, if you still encounter the "Error No Such Partition. Grub Rescue" issue despite these steps, you should consider proceeding to the next method.
Reinstalling the Grub Bootloader
Sometimes, the issue may lie with the Grub bootloader itself. A corrupted or incorrectly installed Grub bootloader can lead to the ‘Error No Such Partition. Grub Rescue’ issue. In such cases, reinstalling the Grub bootloader can resolve this problem.
To reinstall Grub, you first need to boot your system from a live Ubuntu CD or USB stick. After booting, open a terminal and run the sudo fdisk -l command to identify the partition on which your system is installed. Once identified, mount that partition.
Next, you need to install Grub onto the proper partition. Run the sudo grub-install /dev/sdX command, replacing X with the hard drive number where your system is installed. Unmount the partition once the installation is complete.
Once done with these steps, you need to reboot your system. If everything has been done correctly, Grub should now load correctly, and the ‘Error No Such Partition. Grub Rescue’ issue should be resolved. If not, continue to the third method.
Using Boot-Repair Tool to Fix the Issue
The Boot-Repair tool is a handy software specifically designed to troubleshoot and fix various boot issues. It can be particularly useful in resolving the ‘Error No Such Partition. Grub Rescue’ issue.
Firstly, to use the Boot-Repair tool, you need to download and boot from a live Ubuntu disk. Once booted, connect to the internet and open a terminal. You can then install the Boot-Repair tool by running the following commands: sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update followed by sudo apt-get install -y boot-repair && boot-repair.
Once installed, run the Boot-Repair tool and choose the recommended repair option. This will automatically detect and fix any boot problems detected by the tool. Once the process is complete, reboot your system. If the ‘Error No Such Partition. Grub Rescue’ issue persists, consider the next method.
Restoring the Partition Table
The ‘Error No Such Partition. Grub Rescue’ issue may also be due to a damaged partition table. In such cases, restoring the partition table may be the best course of action. You can use software like TestDisk to recover a lost partition and fix the partition table.
Install TestDisk on your system and launch it with administrator privileges. Follow the prompts to select your hard drive and partition table type. On the next screen, select the ‘Analyse’ option to have TestDisk check your partition structure and search for lost partitions.
If TestDisk finds any lost partitions, it will list them for you. You can then choose to write the new partition structure to the disk, restoring the lost partitions. Once done, reboot your system and check if the issue is resolved.
Reinstalling the Operating System
If none of the above methods work, the ultimate solution could be to reinstall your operating system. Reinstalling the operating system will create a new partition table and install a fresh copy of Grub, which should eliminate the ‘Error No Such Partition. Grub Rescue’ issue.
First, backup all the important data on your system. Next, create a bootable USB or DVD of the operating system you wish to install. Boot your system from this USB/DVD and follow the instructions to install the operating system.
Remember, though this method is effective, it should be considered as the last resort due to the loss of data involved.
