Hello This bug is introduced by syslinux-common. I found on syslinux mailing list information that downgrade of this package has resolved the bug. Here is the link http://www.zytor.com/pipermail/syslinux-commits/2011-July/001446.html. I build the netboot.tar.gz on linux system with debian 7.5. I created debian SID enviroment with debootstrap a then i used chroot. After that i used manual how to build debian installer. When i used the build netboot.tar.gz on PXE boot the error message was failed to load ldlinux.c32. I think the bug is present in sid. I also found older bug report with error message Failed to load ldlinux.c32. Bug number is 699884.
Thank You Have nice Day ewew
