Unsupported section "BootOrderSection" (Virtual hardware device boot order)

I have a Linux VM running on fusion, and using ovftool to convert this .vmx into .ovf, then import into a ESXi 5...unfortunately having this error message.

I tried the -lax option, but doesn't help...I look into the ovf file, and found it could be this section issue

    <vmw:BootOrderSection vmw:instanceId="7" vmw:type="disk">

      <Info>Virtual hardware device boot order</Info>

    </vmw:BootOrderSection>

Anyone can share me some light to get around this...thanks
