Thank you zorphnog. I tried several location to putting the bootmgr.exe.mui file in the WDS(Windows deployment service). But I can't change Message Text & Color at the plogress bar . I think WDS put the bootmgr.exe to Taget PC by tftp, but WDS does not put bootmgr.exe.mui file to target PC,though bootmgr.exe doesn't know the bootmgr.exe.mui. Boot from DVD is OK, and boot from WDS with "BCD : quietboot yes" is OK. If anybody know how to try with WDS, please teach me it. Thank you everybody.
