Why is My PC Stuck on Diagnosing Your PC?

Many users complain that their Windows PCs are unable to boot up properly and get stuck on a screen that says something like "Diagnosing Your PC." This screen is part of the Windows recovery environment. It is usually shown when the operating system encounters issues that prevent it from starting.

Here are some common reasons why this issue occurs:

➤ Corrupted System Files: If important system files are damaged, Windows may struggle to load properly, leading to this error.
➤ Boot Configuration Data Corruption: The BCD file contains crucial data for booting Windows. BCD errors can prevent Windows from starting and result in the "Diagnosing Your PC" screen.
➤ Hard Drive Issues: Physical or logical issues with your hard drive, such as bad sectors or disk corruption, can cause boot failures.
➤ Windows Update Problems: Sometimes a failed Windows update or an incomplete installation can trigger this error.
➤ Hardware Failures: Faulty RAM, motherboard, or other components can also lead to system boot errors.

Step 2: Wait for about 30 seconds to ensure that all power is discharged.
