With the development of information technology, Electronic communication equipment is an indispensable tool for data transfer, especially the computer. Microsoft Windows operating system occupies most of the market land. The most common Windows operating system includes Windows 7, Windows 8, Windows 8.1, and Windows 10. However, we are going to talk about Windows 7 today. Sometimes, you may want to fix Windows 7 boot with Command Prompt when the Windows 7 PC refuses to boot.

Possible reasons for Windows 7 fails to boot

Generally, you get these errors due to these elements:

1. Incorrect boot order sequence in BIOS. Thus, check your BIOS boot order to make sure the system hard drive is the first boot device.

2. Damaged system hard drive. Run anti-virus software to see if there is malware, or you might have to replace the system hard drive with a new one.

3. Corrupted system files, including the MBR (Master Boot Record), boot sector, BCD (Boot Configuration Data), etc.

The first two factors are easy to resolve. We are going to describe the last factor that caused Windows 7 boot problems.

About MBR & Boot Sector& BCD

The MBR is the first sector of the system hard drive that tells the computer how to load the operating system and how to partition the hard drive, including the master boot code (called a small amount of executable code), the disk signature, and the partition table for the disk.

The Boot sector is a region of hard disk that contains machine code to be loaded into RAM by the computer system’s snap-in firmware. It allows the boot process of a computer to load the operating system stored on the same disk.

The BCD involves the configuration data required to boot Microsoft Windows Vista, Windows 7, and later.

Therefore, if any of the three system files is damaged or corrupted, you cannot boot Windows 7 properly.
