Error code 0xc0000185 almost always occurs when you boot your Windows computer, usually after rebooting your system. It almost always appears as a BSOD (Blue Screen of Death) with the text “Your PC boot configuration data is missing or contains some errors” followed by an error code.
It is also possible that the message reads as follows: “Your computer needs to be repaired. The boot configuration file does not contain some required information”. In most cases, this error can be easily fixed.
Causes of blue screen recovery error 0x0000185
Damaged BCD data: Another potential culprit that can cause this problem is corrupted BCD data that prevents the boot process from completing. In this case, the problem can be solved by opening a command-line window from the Troubleshooting menu and running a series of commands to restore the BCD data.
Damaged system files: Damaged operating system files can also cause this error code during the boot sequence. In this case, you may be able to fix the problem by performing a restore installation or a clean installation.
