Routine Description:

    This routine ensures that critical boot files (ntldr and $ldr$ on x86)
    are uncompressed. On ARC we also make sure setupldr is uncompressed,
    even though this is not strictly necessary since the system partition
    is always supposed to be FAT, just in case.

Arguments:

    ParentWindow - supplies window handle for window to act as parent/owner of
        any ui windows this routine may display

    TellUserAboutError - if TRUE and and an error occurs, the user will get
        an error message. Otherwise the routine does not tell the user
        about errors.

Return Value:

    Boolean value indicating whether relevent files were processed
    successfully.
