    This is from one forum about this error. In addition to this situation, you can know more cases below.

    When Does The Error Happen


    Now, suppose that there are two systems, Windows 10 and Ubuntu. You may choose to do some disk and partition operations to these two operating system partitions on the same hard disk, especially Ubuntu OS partition. However, in some circumstances, error no such partition in Windows 10 happens.

    • Delete Ubuntu Partition
      For a long time, you don't like such a system because you may think this command line based system is difficult to use, so you want to uninstall it for a new partition creation. Or there is only a bit of free disk space left, so you decide to delete such a partition to free up some disk space and extend your other partitions.
    • Resize/Merge/Split Partition
      When managing your hard drive, such as resize/merge/split Ubuntu partition, perhaps this issue appears when restarting your computer.
    • Reinstall Ubuntu OS
      Sometimes, you reinstall Ubuntu operating system for some reasons including system breakdown, or system file damage.
    • Restore Ubuntu OS to the Old Version
      After making an upgrade, some issues often appear, so some of you choose to restore to the old Version, such as Ubuntu 8.X.

    Why No Such Partition Grub Rescue Windows 10 Occurs


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

    • Reason 1: Generally speaking, the most common reason of this error is due to a misconfigured boot loader file. While installing Ubuntu in Windows, a part of Grub lives in the Master Boot Record (MBR), while the other parts live in the Linux boot partition. That is to say, although the Ubuntu partition is deleted, Grub is still in MBR. In addition, the active partition is not set correctly. As a result, on the startup of operating system Windows 10, you receive such an error of "no such partition grub rescue".
    • When resizing Ubuntu partition, UUID is modified, so Grub can't read the boot information.
    • When reinstalling Ubuntu system, you may install it to a new partition, and the original partition has been formatted, but you haven't reinstalled Grub 2.
    • While restoring to Ubuntu 8.X, the Grub is the version 1, so Grub 2 is damaged.

    But what should you do to fix it and ensure the operating system boot normally? Please try the following solutions one by one now.

When Windows 10 is unable to boot, if you restart system several times, the system will enter into WinRe mode. Sometimes Win 10 system will go to Automatic Repair interface automatically or you can use a Windows 10 installation disc to go into this recovery environment.

    restore Restore the Boot Sector Code with Windows 10 Automatic Repair

    1. Firstly connect your USB flash drive to your computer. Or insert Windows 10 DVD to PC.
    2. Then you need to restart the computer several times to enter into Automatic Repair.

    diskpart
    select disk 0
    list volume

    6. Next type the command lines:

    Exit
    F:
    cd boot
    Dir


    7. Then you should check if you have bootsect.exe files in the list. If so, enter the following command:

    bootsect /nt60 SYS /mbr
    Exit


    restore boot sector code

    8. Restart your computer.

    It is complicated to use commands to rebuild BCD and MBR, and here to use a third-party tool should be wise, just like the above content shows.

    solution 2 Solution 2: Manually Configure the Active Partition


    restore Use Diskpart
    In addition to MBR issue, another common factor of no such error in Windows 10 is that you didn't set the correct partition in active. If you want to ensure your computer can boot normally, you must set partition active. When booting PC, the BIOS will start up the boot loader from an active partition. Otherwise, many issues including "Error: no such partition" are easy to appear. How to do this work? Also, run Command Prompt by entering into WinRE.

    1. Type diskpart.
    2. Then type the following commands one by one:

    • list disk: all hard drives in your computer will be displayed.
    • select disk n: n means the disk where Windows 10 is installed. Here I choose disk 0.
    • list volume: all volumes on disk 0 is listed.
    • select volume n: n refers to the number of system partition.
    • active: it can mark the correct system partition active.
