When encountering the error "This computer needs to be repaired", you can troubleshoot and solve it yourself. The specific steps are as follows: 1. Check the hard disk connection or hardware problems, try to unplug the hard disk cable or check the power supply, eliminate poor contact or peripheral interference, and if the hard disk is aging, it needs to be replaced; 2. Use the automatic repair tool (Windows RE), and execute bootrec /fixmbr, bootrec /fixboot, bootrec /rebuildbcd in turn to repair the boot problem through the command prompt; 3. If the startup repair fails, try to restore or reset the system, choose to keep the files or delete all contents to reinstall the system, and confirm the data backup situation in advance.

When encountering the error "This computer needs to be fixed", many people's first reaction is to reinstall the system or ask for help. In fact, although this problem seems serious, it can often be solved by itself. The key is to figure out the reasons why the system cannot be started and follow the steps step by step.

The following situations basically cover common causes and corresponding solutions:

1. Check hard drive connection or hardware problems

Sometimes this error is not because the system file is broken, but because something is wrong with the hard disk itself. For example, the data cable is loose, the hard disk power supply is unstable, and even the motherboard interface is poor.

• You can try turning off the computer and unplug the hard drive's data cable and power cable (if it is a desktop computer).
• If it is a laptop, it is recommended to send it to check whether the internal connection is normal.
• If there are external devices (U disk, mobile hard disk, etc.), unplug them first and try to turn them on.

Note: Aging of the hard drive or bad channel may also cause this kind of problem. At this time, you need to back up important data and consider replacing the hard drive.

2. Use the Auto Repair Tool (Windows RE)

When the system fails to boot normally, it will automatically enter the recovery environment (Windows RE). You can run the automatic repair command through it.

The operation steps are as follows:

• Insert the installation USB or recovery disk and boot from the media.
• Go to Repair Computer > Troubleshooting > Advanced Options > Command Prompt.
• Enter the following command and execute:

 bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

These three commands are used to repair the main boot record, boot sector and rebuild BCD (boot configuration data). After the run is completed, restart to see if it returns to normal.

3. Startup repair failed? Try system restore or reset

If the above method is not effective, it means that the system may have been seriously damaged.

System Restore:

If you have set a restore point before, you can select "System Restore" in the recovery environment to restore the system to the state before the error occurs.

Reset this computer:

If the restore is not possible, you can try "Reset this computer". There are two ways:

• Keep my files : Reinstall the system only, keep personal files.
• Delete everything : It is equivalent to a thorough reinstallation, suitable for situations with serious problems.

Remember to confirm in advance whether there is any important data that needs to be backed up, but if you can't enter the system, it may be difficult to back up.

Basically these are the methods. Sometimes the problem may be solved quickly, such as re-inserting the hard drive cable; sometimes it takes a complete process to solve it. The key is not to rush to throw away the computer or blindly reinstall it. It can be handled step by step.
