The easiest method of checking existing entries within a BCD store is to use the bcdedit tool with the /enum switch. Entering the command bcdedit.exe /enum ALL will display all entries. Adding the /v switch (e.g. bcdedit.exe /enum ALL /v) will omit the use of well-known identifiers such as {bootmgr} and will display full identifiers.
Please refer to the enum command for a list of supported arguments. To output to a .txt file use the command syntax bcdedit.exe /enum ALL /v > C:\bcd_contents.txt
Output after executing command bcdedit.exe /enum [enter]

Output after executing command bcdedit.exe /enum ALL /v [enter]
It's also possible to limit the type of entry to display. Supported types are listed in the enum help. To display all operating system entries for example, we would type bcdedit.exe /enum OSLOADER [enter]
