SCCM 2012 R2 PxE can't boot - your pc need to be repired.

Dear All,

These days, I upgraded SCCM 2012 to R2 , after that PxE can't boot , and shows a blue screen that your pc need to be repired, same issue like this:http://www.gerryhampsoncm.blogspot.ie/2013/02/sccm-2012-task-sequence-fails-with-bcd.html

And, i have also re-configed the pxe more times follow by this acticle , and still failed.

And, after I replace the \RemoteInstall\SMSTemp\2014.01.08.12.31.26.01.{xxxxxxxxx}.boot.bcd to \RemoteInstall\Tmp\x86x64{xxxxxxx}.bcd, and the PC can boot to the winpe well. that means the pc using Tmp folder's BCD store to boot to WinPE, and not using SMSTemp's.

I check the PxE process:http://technet.microsoft.com/en-us/library/cc722358(v=ws.10).aspx

PXEBoot.com downloads Bootmgr.exe and the BCD store, and I think PXEBoot.com should download BCD store from SMSTemp folder, and should not be the Tmp folder.

So, my question is that why te PXEBoot.com download BCD from Tmp folder ? And how can I change it to download BCD from SMSTemp folder. ? I have been getting to crazy about this fucking problem.
