Error: No Such Partition. Grub Rescue

"I have a dual-boot setup with Windows 10 and Linux Ubuntu on my desktop. As the OS failed to detect Ubuntu during the restart from the initial menu, I deleted the partition where Ubuntu was installed from within Windows 10. Then, I installed PowerISO which prompted me to restart the system. But now, it boots into the GRUB rescue prompt displaying: no such partition. Grub rescue. How do I fix the no such partition grub rescue in Windows 10 issue?"

"Unable to find a live file system" is a common error that usually appears in a dual-boot system with Windows and Ubuntu. You'll see this error message when you try to start your computer but get stuck at the boot screen with the following:

Example 1:

Error: No such partition.
grub rescue>

Example 2:

Error: no such partition.
Entering rescue mode...
grub rescue>

The "Error: No Such Partition Grub Rescue" message could occur due to several reasons, mainly related to the GRUB (Grand Unified Bootloader) boot loader. Here are some common causes: 1. **Missing or Damaged GRUB**: This error might appear if GRUB is not installed correctly, or its files have been deleted or corrupted. 2. **Wrong Partition Table**: If you've recently made changes to your partition table, such as deleting or resizing partitions, GRUB might not be able to find the operating system's boot partition. 3. **OS Installation Overwritten**: Installing a new operating system, especially if it's not Linux, might overwrite the GRUB bootloader, causing this error. 4. **Bootloader Conflict**: Having multiple bootloaders can sometimes cause issues. For example, installing Windows after Linux may lead to the Windows Boot Manager replacing GRUB. 5. **Hardware Failure**: In rare cases, a failing hard drive or damaged sectors could lead to this issue. 6. **Incorrect Boot Configuration**: Incorrect settings in the BIOS/UEFI configuration, like selecting the wrong boot device, can also trigger this error. Remember, "Error: No Such Partition Grub Rescue" typically appears when your computer tries to boot and cannot locate the GRUB bootloader or the operating system it's supposed to load. To resolve it, you may need to use a live Linux USB/DVD, boot into rescue mode, or re-install GRUB.

The GRUB rescue scenario can happen on Windows 10 for the following reasons:

• Broken boot loader
• Wrong partition enabled
• Invalid boot loader configuration
• Corrupted boot sector code
• Deletion/resizing/splitting/joining of Ubuntu partitions

We hope that these solutions help you fix the “No such partition” and “Grub rescue” error on Windows 10. If they worked for you, feel free to share them with others using the social media buttons.

Try these practical solutions to fix the Windows Boot Manager GRUB rescue error.

• Repair MBR and rebuild BCD
• Use Windows 11/10 Automatic Repair to Restore Boot Sector Code
• Manually Configure and Mark the System Partition as Active

1 - Repair the MBR and rebuild the BCD

Part of GRUB is located in the Master Boot Record (MBR), and the rest is on the Linux boot partition. Usually, when you get the “grub rescue no such partition” error on Windows 10, it's because you've deleted or formatted the Ubuntu partition, which messes up the MBR boot sector and the boot sector code file, rendering Windows 10 unbootable.

Now, you can try to rebuild the MBR and restore the BCD file to fix the issue. Both partition managers and Windows 10 built-in repair tools can help you with the Windows 10 Grub rescue problem.

Method 1: Rebuild the MBR Using Disk Management (Recommended)

Partition Master makes disk partitioning on Windows 11/10/8.1/8/7/Vista/XP incredibly easy and allows you to make the best use of hard drive space for optimal PC performance. With this tool, you can easily rebuild MBR with a wizard-like interface.

Aside from checking and repairing partitions, Partition Master also provides an all-in-one disk partition management solution, such as resizing/moving partitions to solve low disk space issues, cloning disks, merging partitions, creating/deleting/formating partitions, wiping data, and converting disks/partitions (e.g., MBR to GPT).

Step 1: Create a bootable WinPE disk

• Launch Partition Master, click “Create Bootable Media” on the toolbar and then select “Create Bootable USB Flash Drive”. • Click “Next” to finish the process.

Step 2. Boot from the Partition Master Live USB

Plug in the bootable USB or CD/DVD to your computer. Restart your computer and press F2 or Del to enter BIOS. Set it to boot from “Removable Device” or “CD-ROM Drive.” The Partition Master tool will then launch automatically.

Step 3: Rebuild the MBR

Click “Tools,” and then select “Rebuild MBR.”

Rebuild the MBR

Select the disk and MBR type, then click “Rebuild”.

Then you'll see “MBR on Disk X successfully rebuilt.”

Method 2: Repair the MBR and Restore BCD with Windows 11/10 Automatic Repair

You can also use the Windows 10 Automatic Repair feature to fix the “Error: no such partition grub rescue” issue. When Windows 10 fails to start, you can restart your system multiple times, and it will enter the WinRE mode. Alternatively, you can use the Windows 10 boot media (DVD or USB flash drive) to access this recovery environment.

This is a step-by-step guide.

Step 1: Connect the Windows 10 bootable media to your computer (DVD or USB flash drive).

2. In WinRE, click the Choose an option tab, and then click Troubleshoot.

Step 3: Click on “Advanced options”. In the next window, choose “Command Prompt” to fix the BCD file.

Step 4. After opening the Command Prompt, type in the following commands one by one:

Repair MBR:
Repair Boot Sector:
Rebuild BCD:

Step 5: Close the Command Prompt window, and then restart your computer.

Rebuilding the MBR and BCD is an effective way to fix the "grub rescue no such partition" error in Windows 10. However, if you're still encountering issues, proceed to the next solution.

2 - Use Windows 11/10 Automatic Repair to Fix the Boot Sector Code

Corrupted boot sector code can lead to the Windows 10 grub rescue error. If rebuilding MBR fails to fix the Windows 10 grub rescue issue, you should consider using the Windows repair options to restore the boot sector code.

Step 1. Restart your PC multiple times during the boot process.

Step 2: From the list, choose Troubleshoot > Advanced options > Startup Repair.

Step 3: The repair process will now begin.

Step 4. Once the repair is done, check if the “No such partition” error is gone.

You can also use a Windows installation disc or USB drive to fix this issue. To begin restoring the boot sector code, do the following:

Step 1. Connect the USB flash drive to your PC, or insert the Windows 10 DVD.

Step 2: Restart your computer and boot into Automatic Repair.

Step 3: Click on “Troubleshoot” > “Advanced options” > “Command Prompt” to open CMD.

Step 4. In the CMD window, type the following command and press Enter:

diskpart
select disk 0
list volume

Step 5. Here, you'll see all the volumes. Under the "Type" column, look for the value "DVD-ROM." Note the drive letter of your Windows 10 installation disc. In this example, it's the letter F. Type the following command line and press Enter:

Exit
F:
Change to the boot directory
View contents of the directory

Step 6: Next, you'll need to check if the list contains the bootsect.exe file. If it does, type in the following command:

bootsect /nt60 SYS /mbr
Exit
bootsect nt60 SYS mbr

Step 7. Close the Command Prompt, and then restart your computer. Check if the “grub rescue no such device” error is resolved.

3 - Configuring and Setting the Active Partition

A common reason for the "Error no such partition" message is an incorrectly set active partition. The BIOS tries to boot the bootloader from the active partition, and the bootloader in turn searches its configuration data from the active partition. Hence, if the active partition is damaged or incorrectly set, you may encounter the "Error: no such partition. Grub rescue" issue.

As shown in the following rebuilding the MBR section, you can make the system partition active either with a disk-partition management tool or by manually entering commands at the Diskpart prompt.

Method 1: Set the active partition with a partition master tool in one click

Step 1: Run the partition manager. Right-click on the partition you want to work with in the drive map and select "Advanced."

Step 2: Then, from the drop-down menu, select “Set as active.” Click “OK.” Choose “Run 1 task” and click “Apply.”

Method 2: Use Diskpart to mark the system partition as active

Step 1. Use Diskpart from the command line to set up the partitions correctly.

Step 2: Connect the Windows 10 bootable media to your computer (DVD or USB flash drive).

Step 3: Restart your computer and boot into Advanced Startup Options.

Step 4. Go to Troubleshoot > Advanced options > Command Prompt to open CMD.

Step 5. Type diskpart and press Enter. Type the following commands in order, pressing Enter after each:

list disk: (This command will list all the hard drives on your computer.)
select disk n: (Replace n with the number of the disk where Windows 10 is installed. You can select Disk 0 or another disk where Windows 10 is installed.)
list volume: (This command will list all volumes on the system drive.)
select volume n: (Replace n with the number of the system partition.)
active: (This command will mark the correct system partition as active.)

Fix "No such partition" Error by Setting Active Partition

Type quit to exit the command prompt. Restart your computer to see if the Windows 10 GRUB rescue error was fixed.
