How to create a WinPE Boot Disk

- You can add some additional tools to the WinPE CD such as ImageX, DSIM, BCDBoot, OSCDimage etc to the WInPE CD, to do so Open a Normal Command Prompt (not the WinPE prompt) and issue the command
  cd "C:\Program Files\Windows AIK\Tools\x86"
  copy *.exe” c:\winpe\iso\

Open another command prompt as Admin and copy tools to WinPE

- Unmount the WinPE image you are working with and commit the changes you made to it by issuing the command:
  imagex /unmount c:\winpe\mount /commit

Unmount the WinPE Image and Commit changes to it

- copy c:\winpe\winpe.wim c:\winpe\ISO\sources\boot.wim

Copy and Rename Boot.Wim

- Run OSCDIMG to create bootable iso as follows

oscdimg -n -h -bc:\winpe\etfsboot.com c:\winpe\iso\ c:\winpe\winpe.iso

-n allows long file names
-b shows the file that will be written in boot sector of the disk
-h allows writing of any hidden files or folders

Run OSCDImg to create the ISO image of the CD

- Your WInPE Boot cd ISO file is now located in C:\WinPE folder by the name WInpe.ISO , you can now burn this file to a CD and boot a machine with it

Initial Screen after booting from CD

Make sure your BIOS boot order lists the CD/DVD first and then you can boot a machine from it. If there is already an operating system installed on the machine, you will be prompted to press a key to boot from CD. The initial screen after booting from the CD is a command prompt. You will need to change to the drive letter of your CD Rom drive to use tools such as ImageX, in our case its F: . If you are ever not sure what drive letter is your CD ROM, you can always issue the command DISKPART /LIST
