BCD (Boot Configuration Data) are a set of data where the information about the system boot is stored and from where the operating systems installed on the computer are managed, this is a new function thanks to which it is possible to allow unmanaged systems by BIOS to boot correctly..

 

All the BCD files are stored in the boot folder to be able to perform administration tasks on them when necessary. In addition, they have an encryption to prevent unauthorized changes to them, this can naturally cause a negative effect on Windows startup.

Boot Configuration Data (BCD) contains the Windows Boot Manager menu in which we find:

 

  • Loading the Boot Record volume
  • System startup using winload.exe
  • Lets you start a previous version of Windows with the NTLDR file

 HKEY_LOCAL_MACHINE \ BCD00000
