Issue: How to fix boot configuration error code 0xc0000034 on Windows?
Ok, so I have a laptop for two months with Windows 10 preinstalled. Everything worked fine until today. I’ve restarted my laptop and get a BSOD with an error code 0xc0000034. I’ve tried reinstalling the system multiple times, but in vain because the error keeps reoccurring. Please help me as I’ve never dealt with such an issue before. Thanks!
Error code 0xc0000034 is a current Windows boot configuration error, also known as BSOD “The Boot Configuration Data file is missing.” Before the screen opens, people might notice prolonged boot preparation sessions, system slowdowns, software crashes, random Internet disconnection, and similar malfunctions. However, the 0xc0000034 error shows up unexpectedly and freezes the Windows screen without even booting the system up.
While the majority of people who have reported a 0xc0000034 error on Microsoft and other IT forums run Windows 10, the bug is not limited to this newest version of Windows. The culprit of the issue is Windows Boot Manager (Bootmgr) entry or rather its lack in the Boot Configuration Data (BCD) store. In some of the cases, 0xc0000034 BSOD may occur due to the Boot\BCD file damaged on the active partition.
