SCCM 2012 R2 PXE boot problems after installing CU4(cummulative update 4)

Running sccm2012 R2 on server 2008 R2.  Things were running great till I updated my sccm2012 R2 with CU4.  Apparently all my boot images are fine in SCCM2012 R2 management console but actually either PXE path or something else is changed.
DHCP is working fine.  Every time I try to boot from PXE after pressing F12:

1) Black screen appears for a long time and after that 'loading file SMSboot\boot.sdi.  Not sure where this path is coming from.  Though on my DHCP option which has never been changed is SMSboot\x64\wdsmgfw.efi.

I checked the Roles and found WDS and Windows update server service has Red cross over them,  Removed PXE role from configuration manager console, waited and

checked if the RemoteInstall directory is removed (it did not completely remove).  Also my boot images were still as it is.  Restarted the server and had to

manually remove the Windows deployment role and removed the Remoteinstall directory.  Still my boot images in system center console were intact.  Restarted the server.  
Enabled the PXE role in sccm console it installed the WDS, new Remoteinstall directory, both problems still exist.

Problem 1)
After pressing F12 Black screen appears for a long time and after that 'loading file SMSboot\boot.sdi.  Not sure where this path is coming from.  On my DHCP server option has never  been touched and its still SMSboot\x64\wdsmgfw.efi, after the update of CU4.  The path under datasource of each boot image, is now '\\SCCM2012.mydomain.com\SMS_FRN\OSD\boot\x64\boot.wim (not sure if this is fine)
Problem2)
PXE E79 nbp is too big for the base memory.

Need help please.  Logs are under;

Options 66/67 are not encouraged and maybe even be unsupported.

boot.sdi should be in remoteinstall folder.

Nagendra,
-No options 66 and 67 exist on my DHCP anymore.
-When I try to uncheck the PXE option on SCCM 2012, it partly uninstalls the remote install folder, DOES not uninstall the boot images, it only uninstalls the WDS server.  
-After restart of SCCM 2012 R2 CU4, I check back the PXE, the WDS is there.  I boot up the client and the same thing happens it just stick to 'loading file......................\smsboot\boot.sdi', though I have deleted the boot images manually and recreated them.  No luck!
Need help I am going in circles with the web articles.
