Why Do I Get a Boot Error Message When I Start My Computer

Today, I turned on my Windows PC, and it showed me a blue screen and a message saying something like 'Your PC/Device needs to be repaired,' and there are complex numbers. The second time I turned it on, nothing showed up anymore. Why do I get the message, and what can I do to fix this? Appreciate for any help!

You are getting the boot error message, and being unable to boot up the computer can be caused by many factors. For example, improper hardware change recently, misconfiguration of the system, corrupted system files, virus and malware attacks, etc.

Those error messages and error codes usually represent the specific cause of the startup issue. You can determine the actual error by searching for the information online. Generally, you can run Startup Repair or SFC and CHKDSK command lines to fix common errors. However, if the situation is too complicated to resolve, you'd better start looking for a professional boot repair tool.

I want to recommend EaseUS Partition Master for its friendly UI and comprehensive functions. Not only can it rebuild MBR, but it also detects and repairs many other errors automatically with its advanced algorithm.
