grub rescue>
To fix this issue, you can make a boot repair USB disk and use the Windows automatic repair feature to troubleshoot. Or you can try some workarounds from the technical forum.
Some users that have previously configured their computers to dual-boot Windows and Linux distributions (most commonly with Ubuntu) are reporting that their PC is entering Grub Rescue Mode and displaying the error No Such Partition – Grub Rescue.
After investigating this particular issue thoroughly, it turns out that there are several different situations that might trigger the apparition of this issue. Here’s a list of potential culprits that might be responsible for this issue:
- GRUB Bootloader is Corrupted or Deleted – If you are seeing this error due to some type of corrupted data associated with the GRUP Bootloader or after you have unwillingly deleted data associated with it, you can fix the issue by manually reconfiguring the utility to boot using the correct files.
- The bootloader is Misconfigured or Corrupted – Since this issue can also occur due to misconfigured or corrupted BCD data, you should be able to fix the issue by rebuilding the Boot Configuration data from an elevated Command Prompt.
- Current Boot Configuration is inconsistent – In case the issue is being caused by bad data that’s being fed into the GRUB bootloader, you can potentially fix the issue by using a Registry Backup to restore your computer back to a good configuration.
Now that you know every potential culprit, here’s a list of methods that other affected users have successfully used to fix the issue and prevent their computer from booting into Grub rescue mode:
Method 1: Manually Reconfigure GRUB Bootloader
By far, the most effective fix and the one you should start with since it’s the least destructive is to manually reconfigure the GRUB bootloader and make sure that the primary OS is prioritized.
Several affected users have confirmed that they finally managed to bypass the GRUB rescue state by following a set of instructions designed to manually reconfigure the GRUP Bootloader to prioritize the main OS.
If this scenario is applicable, follow the instructions below to do so directly via the GRUB Rescue menu:
- Once your PC enters GRUB Rescue Mode, type the following command and press Enter to get an overview of all your available partitions:
ls
- After you do this, you should get an overview of all partitions that you currently have on your primary disk. At this point, you need to make sure that you select the primary OS. In our case, the correct partition is (hd0,msdos2), so we used the following command to interrogate the partition:
ls (hd0, msdos2)
Note: Make sure to replace the partition with the correct example in your case. If you get a message saying something like ‘File System is ext2 or ext3‘, you have correctly identified the partition that holds your primary OS.
Note 2: If you interrogate a partition and you get the message ‘Filesystem is unknown‘, you didn’t select the correct partition.
Incorrect partition error message in GRUB - Once the correct partition is selected, type the ‘set‘ and press Enter to interrogate and get a definitive listing of your main partition.
- Next, type the following commands and press Enter after each command to change the priority of GRUB Bootloader to the correct one:
set boot = (hd0, msdos5) set prefix=(hd0, msdos5)/boot/grub insmod normal normal
- After you input the final command, you’ll be taken to the main GNU Grub menu. Once you get to this screen, simply select the OS that you want to boot from and press Enter.
Booting from the main partition in GRUB
In case this method didn’t work for you and the booting sequence eventually boots in the same No Such Partition -Grub Rescue error, move back to the next potential fix below.
Method 2: Rebuilding the Boot Configuration Data files (BCD)
If the first method didn’t work for you, the next step would be to use the Boot Configuration Data (BCD) utility to locate the Windows installation files on all disks and add them back to the boot list so that the booting sequence can locate it during startup.
This method was successfully used by a lot of users that were previously dealing with No Such Partition – Grub Rescue error. Rebuilding the BCD file clusters successfully allowed them to dual-boot normally without being forced into the GRUP Rescue menu.
IMPORTANT: This method will require you to plug in a compatible installation Windows installation media. If you don’t have one at the ready, you can create the Windows installation media from scratch and load it on a USB drive.
Once you meet all requirements, follow the instructions below:
- Plug-in the USB stick containing the installation media and start your computer normally via the power button.
- Access the Setup key by pressing the correspondent button depending on your motherboard manufacturer.
Accessing the BIOS / UEFI Setup menu Note: The setup key will be different from manufacturer to manufacturer. Most commonly the Setup key is either one of the F keys (F2, F4, F6, F8), the Esc key, or the Del key (on Del computers/laptops). If you’re having trouble accessing the Setup menu, search online for specific instructions on accessing it.
- Once you’re inside the Setup menu, access the Boot tab and make sure to set the USB stick containing the installation media as Boot Option #1.
Booting from the installation media - Save the changes, then restart and allow your computer to boot from the installation media and wait for the installation files to load.
- Once you get to the first page, click on Next, then click on Repair your computer from the bottom-right corner of the screen.
Repairing Computer via installation media - Next, wait for the Recovery menu to load, then select Troubleshoot and click on Command Prompt from the list of available options:
Accessing the Command Prompt via the Recovery menu Note: On certain Windows 10 versions, you might also be able to boot from the Recovery menu by forcing 3 consecutive system interruptions during the startup procedure.
- Once you’re inside the elevated Command Prompt, type the following command and press Enter to fix the MBR dependencies associated with your Windows installation:
bootrec /fixmbr
- Once the command is processed successfully, type the following commands and press Enter to fix the Boot Configuration Data associated with your Windows installation:
bootrec /fixboot
Note: If you get the ‘Access is denied’ error while inputting one of the 2 commands above, follow these instructions to fix the bootrec access problem.
- Next, type the following command and press Enter to scan all your disks for the Windows installation media:
bootrec /scanos
Note: This operation might take some time depending on the size of your partitions. Don’t close this window until the operation is complete.
- If the operation is completed successfully, type the following command to effectively rebuild the BCD configuration data:
bootrec /rebuildbcd
- When asked to confirm, type Y and press Enter to confirm and start the operation.
Confirm the operation of building the BCD file system - Finally, type ‘exit’ and press enter to effectively leave the elevated CMD prompt and allow your Windows to boot normally.
In case the end result is the same (the boot attempt ends with the same No Such Partition error), move down to the next method below.
Method 3: Using the Registry Backup to Restore the last good Configuration
If none of the methods above have worked for you, you might be able to fix the current configuration with the last known good backup that should allow you to dual boot without issues.
Doing this will require you to use the Advanced Options menu to open an elevated Command Prompt and run a series of commands that will allow you to boot using the last known good configuration.
This method was reportedly used successfully by a lot of users dealing with the No Such Partition -Grub Rescue error.
In order to use the Registry Backup to restore the last known good configuration, follow the instructions below:
- Insert a compatible Windows installation media and boot from it by pressing any key when prompted to do so.
Booting from the installation media Note: If you don’t have a compatible installation media or your system doesn’t boot from it, follow steps 1 to 4 from Method 2.
- Once you manage to successfully boot from the installation media, click on Repair your computer from the bottom-left corner of the screen.
Repairing your computer - Once you’re finally inside the Advanced Recovery menu, click on Troubleshoot, then click on Command Prompt from the list of available Options.
Accessing the Command Prompt via the Recovery menu - Once you are inside the elevated Command prompt, type ‘C:‘ and press enter to access the partition where you installed Windows. If you installed Windows on a different partition, replace the letter accordingly.
- Next, type ‘dir‘ and press Enter to access the root location of your OS drive.
Note: It’s recommended to back up the current registry before going forward. To do this, input the following command and press Enter after each command:cd \windows\system32\config MD backup copy *.* backup
Backing up the Registry - Next, type the following commands and press Enter to access the last known good configuration and modify the default behavior to boot from it:
CD regback copy *.* ..
- When prompted by the prompt, press A and hit Enter once again.
- Finally, type exit and press Enter to exit and boot normally. This should take you to the main GRUP menu where you should be able to dual boot as you see fit.

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

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”.
Rebuild MBR
- 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.

Ever get into the freaking condition, when your system doesn’t boot successfully and throw your control to a grub rescue utility informing the following error?
error: no such partition. Entering rescue mode... grub rescue>
I went through this situation today. And here is how I rescued with it.
Note: Other possible solutions might be available, but this is just what worked for me. You are recommended to explore the web first, then go with the solution that suits *your* condition perfectly.
1. Reason
Actually, I was trying to resize my Linux (Ubuntu 16.04 LTS) partition which is dual booted with Windows 10. For that, my first step was to unallocate the partition which I wanted to merge with my ext4 (Linux partition). For this, first I logged in Windows and tried to unallocate the partition I wanted to merge (Local Disk :D) but I found out that it can be done with Gparted from Ubuntu as well. But still.
“I started to explore windows storage management console, and a couple of times I detached and reallocate this partition, together with separating out a partition of 3 GB from it. I was just playing and testing the working of the console. But this fun, lead me to freak, later in the day.”
2. Problem
Now the next step was to use Gparted from Linux. But for that, I needed to reboot and login to my Ubuntu 16.04 LTS and here is the twist. When I did reboot my laptop to switch the OS. Oh my God! I get encountered with this scary error.
error: no such partition. Entering rescue mode... grub rescue>
I was screwed up! I didn’t know what the hack is done with my system.
I searched the web and found out the reason for this error that was “I deleted a Windows partition. and somehow (I don’t know how), I messed up with some grub configurations.”
3. Solution
But something worked like heaven for me. Here is the solution, if you ever get into this, proceed as follows.
4. List File Systems
error: no such partition. Entering rescue mode... grub rescue> ls (hd0) (hd0,msdos5) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1)
This “ls” command will list possible file systems where grub might be available. Now our next step is to find out, that which among these listed systems is the one that we can use for booting.
5. Find the File System we may use to boot
grub rescue> ls (hd0,msdos1) (hd0,msdos1): Filesystem is unknown. grub rescue> ls (hd0,msdos2) (hd0,msdos2): Filesystem is unknown. grub rescue> ls (hd0,msdos3) (hd0,msdos3): Filesystem is unknown. grub rescue> ls (hd0,msdos5) (hd0,msdos5): Filesystem is ext2.
Hurray! we have found out, that which filesystem we have to choose for booting. In this case, it is (hd0, msdos5).
6. Configuration
grub rescue> set root=(hd0,msdos5) grub rescue> set prefix=(hd0,msdos5)/boot/grub grub rescue> insmod normal grub rescue> normal
After this, I could see the old booting menu, where I may select between Ubuntu and Windows. At this point, it seems that the problem is solved, but that’s not the truth!
Now if you again reboot your system, you will again get into this grub rescue. If you want to permanently fix this issue. Proceed as follows (after step 3).
7. Updating System grub
Login to Ubuntu and just give these 2 commands.
$ sudo update-grub $ sudo grub-install /dev/sda
Now try to reboot! Hopefully, you are back to your previous experience of booting. After going through this, now I don’t feel that grub rescue is a freaking issue, on the other hand, it’s a simple utility to rescue our system with faulty grub configurations.
Updated:
- Unfortunately, sometimes this process doesn’t work. I recommend you to have a look at this post if you want to give a try to recover your files.
- Recently, I found out here, that sometimes
insmod normaldoesn’t work due to the absence of a complete path ofnormalmodule. If this is the case, please try the complete path withinsmod (hdX, Y)/boot/grub/normal.mod. If this doesn’t work please try the command using “semicolon” instead of “coma” after “hdX” as pointed out here. - Also, the location of the complete path to
normal.modis not consistent across all the systems. Therefore, you may uselsorsearch.filecommands to find out the exact location of your system’s `normal.mod` as explained here. - In my case, I didn’t get into condition when
insmod normaldoesn’t work. So, all these additional updates, I have not performed myself. Therefore, I request you all if any of these *updated* points doesn’t work or if you see a bug in these, then please let me know in the comments section below.

When I was back with my Linux and an unallocated partition, I proceeded ahead for my goal of re-sizing. Explore the second part of this journey on How to resize your Linux partition with Gparted?
