  • It failed to open the boot configuration data storage.
  • lt states, "Boot BCD is missing or corrupt."
  • Error: "The requested system device cannot be found.
  • "When attempting to access BCD, access is denied."

Why The Boot Configuration Data Store Could Not Be Opened

Look at a real example from the Microsoft community forum to see the context of the error. 

For some reason, BCDedit won't open for me now. I've used it before in Windows Vista to edit OS description names on my dual-boot (XP-Vista) system, but now when I go into the command prompt and type in BCDedit, it returns "The boot configuration data store cannot be opened. Access is denied." I'm logged in as administrator (as I was the previous times that I had used it), but suddenly, it won't open now.

This case is a perfect example of the problem many Windows users encounter. 

So, continue reading to discover the underlying variables in the "Access is denied" problem.

  • Lack of Command Prompt Window Privileges. Administrative rights are necessary to access BCDedit. The "Access is denied" issue may appear if the command prompt is not launched as an administrator.
  • Missing Startup Configuration Data File. If the startup configuration data file is missing or damaged, Windows will encounter this issue because it cannot retrieve the essential boot data.
  • Boot Partition Type and Disk Partition Table Inconsistency. When the boot partition type (MBR or GPT) and the disk's partition table are incompatible, BCD access may be hampered, and errors may occur.


The "Boot Configuration Data Store Could Not Be Opened" error is frequent and distressing for Windows users. It may cause the boot process to fail and cause other issues.

However. the EaseUS Partition Master Tool is a highly effective and simple solution after examining other approaches to this issue, each with a different level of efficiency and complexity.
