Re: PXE Rep stalls on Lenovo X230 laptop at the MTFTP start

Hey Jim,

Just a workaround that we have found for a similar issue to this with the newer T440 series of Lenovos.

Our T440, T440s, T440p did the exact same thing, if we chose Managed PE or WinPE Menu it would flash the MTFTP and then disappear and hang indefinitely.

I modified the Boot.wim on my PXE rep using gimagex to mount it (the image), then went into the system32 folder and changed the %errorlevel% variable for the boot choice selection to 1 in the startnet.cmd file.  This forced the PXE mode to always be PXE Menu.  You can change that to your preference if you only use manged or whatnot.  But after that we went into PXE and booted the machine to Provisioning WinPE (no other options worked but this one interestingly does).

Again the steps are as follows if you want to try it.

     PXE Rep:

          -Modify Boot.wim in the LANDesk\PXE\system\images\boot folder

               -Mount with gimagex or just use imagex (requires it be mounted to an EMPTY folder)

          -Modify the startnet.cmd file in boot.wim\windows\system32\startnet.cmd

               -Change the following:

                         ------------------------Original Script lines---------------------------------

                         \cba8\GetBootOptions20 > \temp_cln.cmd

                          set /a option = %errorlevel%

                         @rem option refer to boot option:

                         @rem -2 means in provisioning vboot (not in winpe2.0)

                         @rem -1 means not in winpe2.0

                         @rem 1 means pxemenu

                         @rem 2 means managed pxeboot

                         @rem 3 means provisioning winpe

                         ------------------------Modified Script lines---------------------------------

                         \cba8\GetBootOptions20 > \temp_cln.cmd

                          set /a option = 1

                         @rem option refer to boot option:

                         @rem -2 means in provisioning vboot (not in winpe2.0)

                         @rem -1 means not in winpe2.0

                         @rem 1 means pxemenu

                         @rem 2 means managed pxeboot

                         @rem 3 means provisioning winpe

                         ----------------------End Script sections------------------------------------

          -Commit and unmount with those changes (note you may need to change the permissions on the file before you can save it as it will probably not be writable.

     -Target Machine:

          -Ensure all legacy modes are enabled in the BIOS and that Secure boot is disabled.

               -Choose network boot (PXE)

               -Select Provisioning WinPE

Let me know if that works for you to get them going until Lenovo fixes the other boot mode.  It's been a lifesaver for us over here.
