Further Reading: Reasons for No Such Partition Grub Rescue Windows 10

You may ask me what the specific factors are causing such a problem on your computer. Here we will give a detailed analysis of this error to you.

1. Generally speaking, the most common reason for this error is a misconfigured boot loader file. While installing Ubuntu in Windows, a part of Grub lives in the Master Boot Record (MBR), and the other parts live in the Linux boot partition.

This means that although the Ubuntu partition is deleted, Grub is still in MBR. In addition, the active partition is not correctly set. As a result, you will receive the error of "no such partition grub rescue" during your Windows 10 operating system startup.

2. When resizing Ubuntu partition,UUID is modified, so that Grub can't read the boot information.

3. When reinstalling Ubuntu system, you may install it to a new partition. Although the original partition has been formatted, you haven't reinstalled Grub 2.

4. While restoring to Ubuntu 8.X, the Grub is version 1. So, Grub 2 is damaged.

Suggestion: Back up Your PC to Avoid System Breakdown

After fixing Windows 10 error no such partition, it is better to back up your operating system so that you can restore the PC to a previous state in case you face any system issue.
