Windows system is down-MBR/ntldr/grldr/Partition Table/

Users who often install computer systems and various software may often encounter a problem, that is, system crashes.

 

Taking the author as an example, I have installed both Windows and Linux systems. After I uninstalled the Linux system, I encountered a Windows system crash. After the computer is powered on, the BIOS information shows that the boot disk or system prompts cannot be found.

Or, sometimes the application software is used to make adjustments to the computer disk partition. If a software bug occurs, the computer system cannot start normally after the partition is adjusted.

 

How to recover the system without losing the User File Information of the original disk (including the operating system without reinstalling the operating system) when the system startup of the software fails is as follows:

 

1. Cause: MBR Error 1

Solution: Download The fdisk software and go to DoS or winpe and run "fdisk/MBR". the system automatically restores normal Windows MBR (refer to Baidu encyclopedia for MBr knowledge ).

 

2. Cause: MBR Error 2 or disk partition table Error

Solution: When the fdisk/MBR command cannot solve the problem of system boot failure, you can use disk management software, such as diskgenius, to recover or recreate the MBR function on the relevant disk, general problems can be solved. Disk partitioning is incorrect. You can also use the disk management software to fix disk information by checking and restoring disk partition tables.

 

3. Cause: problems caused by ntldr or grldr loss or errors

Solution: copy the ntldr or grldr file from the system partition disk of a normal computer and paste it to the system disk of the crashed computer to solve the problem.
