Creating a BCD file

This entire process is done in Command Prompt. Be sure to run it as Administrator.

Create a BCD store using bcdedit.exe.
```
bcdedit /createstore c:\BCD
```

Configure RAMDISK settings.

bcdedit /store c:\BCD /create {ramdiskoptions} /d "Ramdisk options"
bcdedit /store c:\BCD /set {ramdiskoptions} ramdisksdidevice boot
bcdedit /store c:\BCD /set {ramdiskoptions} ramdisksdipath \boot\boot.sdi
bcdedit /store c:\BCD /create /d "winpe boot image" /application osloader

The last command will return a GUID. For example:

The entry { bb254249-93e9-11e7-84cb-6c71d9da760e } was successfully created.

Copy this GUID for use in the next set of commands. In each command shown, replace "GUID1" with your GUID.

Create a new boot application entry for the Windows PE image.

bcdedit /store c:\BCD /set {bb254249-93e9-11e7-84cb-6c71d9da760e} device ramdisk=[boot]\Boot\boot.wim,{ramdiskoptions} 
bcdedit /store c:\BCD /set {bb254249-93e9-11e7-84cb-6c71d9da760e} path \windows\system32\winload.exe 
bcdedit /store c:\BCD /set {bb254249-93e9-11e7-84cb-6c71d9da760e} osdevice ramdisk=[boot]\Boot\boot.wim,{ramdiskoptions} 
bcdedit /store c:\BCD /set {bb254249-93e9-11e7-84cb-6c71d9da760e} systemroot \windows
bcdedit /store c:\BCD /set {bb254249-93e9-11e7-84cb-6c71d9da760e} detecthal Yes
bcdedit /store c:\BCD /set {bb254249-93e9-11e7-84cb-6c71d9da760e} winpe Yes

Configure BOOTMGR settings (remember to replace GUID1 in the third command with your GUID).

bcdedit /store c:\BCD /create {bootmgr} /d "boot manager"
bcdedit /store c:\BCD /set {bootmgr} timeout 30 
bcdedit /store c:\BCD -displayorder {bb254249-93e9-11e7-84cb-6c71d9da760e} -addlast

Copy the BCD file to your TFTP server.
```
copy c:\BCD \\PXE-1\TFTP\Boot\BCD
```

Your PXE/TFTP server is now configured. You can view the BCD settings that have been configured using the command:

bcdedit /store <BCD file location> /enum all

Example of BCD settings:

C:\>bcdedit /store C:\BCD /enum all
