How to Repair Windows 10

How to Repair Windows 10

Today we return to the issue of Windows boot errors, although in this case, we will focus on errors that appear in the boot sector or Windows boot. These errors make the operating system unable to boot even in safe mode. Today we will see how to fix startup in Windows 10 for possible errors to arise.

Using these techniques that we will see below, we will repair various Windows startup errors.

 

What types of errors affect Windows startups.

Basically, these errors affect the executable file “Winload.exe,” responsible for finding the active partition where the operating system is located to run the boot. In turn, this program performs the Ntoskrnl.exe process to boot.

We may encounter various error messages like “0xc0000605” or “bootmgr missing” or error code after an update “0x00000f”

We will then see what solutions we have at our disposal to try to repair startup in Windows 10

 

Repair Startup on Windows 10 with Recovery Media (WinRE)

Using this method, we will not need any DVD or USB installation of Windows 10. We will use the system’s own recovery environment when it detects boot or other problems.

If we do not directly access this environment at startup, what we will do is turn on the computer, and when Windows starts to load, we restart. Thus we repeat the procedure up to 3 or 4 times. Then we will get to the next window.

  • We let the recovery environment load for a few minutes the different tools until we find ourselves in the recovery options window.
  • Once inside, we choose the “advanced options” option
  • On the next screen, we will have to choose “Solve problems.”
  • Again we choose “advanced options” we will finally see all the recovery options that we will have available
  • In this tutorial, the option that interests us is the one of “Startup Repair.”
  • Then, we choose this option, and the system repair process will begin.

 

Repair startup in Windows 10 using installation media

We can also find the case in which we can not access WinRE due to an error that directly affects the start of any element of the system.

In any case, what we will have to do is create one of these two drives. We recommend creating a bootable USB in case we then have to reinstall Windows.

We must place the drive on a port or floppy drive on our computer and boot it. In addition, we need this drive to boot before the operating system itself. To do this, visit our tutorial on modifying the BIOS boot sequence.

Once the previous preparations have been made, we start the installation unit, where the main installation screen will appear.

  • We must click on the option of “Repair equipment.”
  • The procedure to be followed is similar. First, we chose “Troubleshooting.”
  • And in this case of the available options, we choose “Command Prompt.”

With the command terminal started, we must type the following command:

bootrec /FixMbr

This command writes the master boot record to the system partition with the boot record. That is, we will overwrite the existing partition table on the hard disk.

We want to write a new boot sector because the previous command has not worked for us (try restarting to see if it has been solved). To write a new boot sector, we write the following:

bootrec /FixBoot

Using these commands should at least repair windows boot correctly. However, it is also possible that the error was not the boot but the system itself. For this case, we will have the following options.

A repair file system with CHKDSK

A star command to perform these actions is CHKDSK.

If you want to find out what we use it for, we recommend the following tutorial:

  • What is CHKDSK, and what is it used for

In this case, from the command prompt as we accessed in the previous section, we execute the following command:

chkdsk <unidad de disco>: /f /r

In

Using this option, the command corrects disk errors, finds bad sectors, and retrieves readable information.

A repair file system with SFC

As an extra option, we also have another command to check the integrity of the system files. To use it, we must type in the command console the following line:

SFC /scannow

Through these options, we will very possibly be able to repair startups in Windows 10. However, if we do not get it, there will always be the possibility of installing the operating system, either in a new installation or updating the one we already have. Of course, if we choose to install a copy, our files will be deleted, so we must be aware of what we do.

To perform these actions, we recommend these tutorials:

  • Restore Windows 10
  • Format Windows 10

We hope this information has solved your problems with Windows startup. If you have any suggestions or want to make some clarification, leave them in the comments.
