    Even the drive letter is E and D is used by another cdrom
    the cdrom is marked as cdrom(0) in the winpe registry [System\controlsetxx\control]

    Ty for the reply

    yes but im wondering if there same variable that was made by the system
    so can be sure

    cos the letters Assigning is not gonna be
    cdrom(0) - D:\
    cdrom(1) - E:\

    mostly by the IDE / SCSI slot #
    and in the registry of WINPE, it will still called cdrom(0) or flashdrive(0)

    i want to make winpe that wont take so much memory
    so it would be best to put all the apps on the usb drive / cdrom not on the ramdisk

    i made simple winpe with explorer and few tools it increase to 900mb ram usage

    Code:
    wmic logicaldisk where volumename="CCCOMA_X64FRE_EN-US_DV9" get deviceid | find /v "DeviceID"
D:
    Since you know the boot device's volume name.
