I have a PC on P4 CPU. And I installed Windows 8.1 Pro into this computer. Now everything is fine. But If I install Windows Updates , my PC doesn't start. It says : Your PC needs to restart. bla,bla,bla.. I already patched ntoskrnl.exe, hal.dll, halmacpi.exe and winload.exe . And I do this .bat: Code: copy C:\WinPatch\hal.dll C:\Windows\System32\hal.dll /Y copy C:\WinPatch\halmacpi.dll C:\Windows\System32\halmacpi.dll /Y copy C:\WinPatch\ntoskrnl.exe C:\Windows\System32\ntoskrnl.exe /Y copy C:\WinPatch\winload.exe C:\Windows\System32\winload.exe /Y exit But I don't know how can I bootable .bat CD. I research it but I couldn't find anything. Please help me. Thanks.
