Can not start windows? Repair it for free from a bootable usb

One of the most common problems that we can find in Windows 10 occurs during its startup. These problems can arise for various reasons, from a corrupted byte on our disk, a faulty boot controller, to a missing registry key. In the event that a problem has occurred with the startup or during the execution of the operating system, we can choose to solve it and repair the PC using the appropriate software.

There are situations that when we are caught by surprise makes us put our hands on our heads without knowing what has happened and how to solve it. We find one of these problems with the fact that when we start our computer we check with amazement how Windows cannot start correctly. An option for its repair is to create a bootable USB with a specialized program.

Windows startup problems and their solution through bootable ISOs

Boot problems in Windows 10 happen because MBR (Master Boot Record) is not foolproof and can get damaged, corrupted, or just disappear. Although the Microsoft operating system has recovery options such as safe mode, this tool may not be able to solve the problem in the event of essential system files or if the hard disk structure is damaged. In that case we will have to resort through specialized rescue and data recovery programs.

For this we can use bootable ISOs that are executed from a USB drive and that have Windows PE distributions, that is, they are operating systems with a reduced version of Windows. These programs are extremely useful for repairing a broken and unstable Windows system, so it is highly recommended to have one installed on a USB stick if necessary.

In the event that we cannot start Windows or we have any internal problems, these disks have several diagnostic and repair tools that allow fixing an MBR, recovering passwords, detecting and cleaning a rootkit, etc. Next, we are going to show you which are the best rescue discs, with which to solve any startup problem in Windows 10.
