    • Data loss due to physical software and disk malfunction.

    Basic Boot Repair

    Broken or missing files in the operating system loader mean that the computer cannot be started and the operation can be repaired. In this case, we recommend that you restore your Windows boot machine as follows:

    Step 1. You will need a Windows recovery CD or bootable USB flash drive to start bootable recovery with your current operating system. Then, when you boot from the installation disc, you and your family will need to select “Repair your computer” on the setup screen.

    This will most likely be followed by an automatic recovery in addition to fixing errors that are clearly preventing the operating system backup from starting normally.

    What is boot loader in MBR?

    Provide a personal bootloader The primary boot machine residing in the MBR is usually a 512 byte image that contains both the platform code and the small partition workspace (see Figure 2). The first 446 bytes are the main boot machine and contain both the executable code and the error message text.

    Unfortunately, automatic recovery methods do not necessarily help with recovery, so sometimes you have to resort to manual recovery from commands Th line.

    Repair Windows Bootloader Via Command Line

    To run the recovery bootloader with this prompt, you first need to deploy it. This can be tried by starting the disc or using the repair and diagnostic menu.

    If you are possibly using a bootable disk, do press Sfit + F10 at the language selection screen.

    You can invoke the command directly from the diagnostics menu by clicking the corresponding icon with the mouse pointer.

    What happens when you rebuild MBR?

    This can be the first 512 bytes of the new hard drive. And in the beginning there is a good boot sector associated with the partition and used to boot the computer. If the MBR is damaged, your computer will be damaged during startup. After the MBR is restored, our computer will boot successfully.

    After opening the command line, enter the following commands:

    • Diskpart (built-in utility for working with hard drives)
    • List of volumes (list of mapped drives)
    • Exit (exit utility)

    This approach helps to know which disk is the Internet model of the system (by default, drive C), and based on this knowledge, a person can perform bootloader file repair in the tutorial.


    Then you will need to type bcdboot to help c: windows solve most bootloader problems.

    It should be noted a little more that if a separate computer is installedOnly a few operating systems have been updated, this method should be applied every time the system is started. This

    If the styling didn’t work, you can completely clear the bootloader and recreate the appropriate files.

  • 1. Download and install ASR Pro
  • 2. Launch the application and sign in using your account details
  • 3. Start a scan of your computer to find and fix any errors

  • Do this: the command line simply opens in any convenient way. Enter diskpart. Then a list of volumes. We then use the bootloader to find the hidden partition (usually it can be a 100-500MB hard drive that was created by the system in FAT32 format by default) and note the letter that belongs to that partition.

    Now you need to run some important commands that will erase and recreate the bootloader.

    • Select volume 5 using the Select Volume & Other command (you can choose a different number instead of 3).
    • ï ® Format the volume using either fs = ntfs command format or select fs = fat32 depending on your disk storage system.
    • Name this handle “Y”. Assign letter = Y
    • Exit the utility to complete the command.
    • Enter bcdboot C: Windows / s Y: / f ALL (letters C and Y may differ depending on youryour system and the number of hard drives). If you have installed multiple more than one operating system, everyone must complete this step to support all boot volumes.

    At the moment, the recovery of the bootloader can only be considered complete.

    Ð Now you need to use it to remove the assigned volume letter. You can also do this by going to the command line like this:

    • Enter each diskpart command.
    • Then you need to display our media list with the contents of the instruction list.
    • Select the volume named Y using the select volume Y command.
    • Remove the name with absent = letter Y.
    • Leave.
