Hi Guys, I have just completed modifying the winntbbu.dll following b0r3d's guide and when I run setup I get the old setup screen. FYI This is what I did. Using a new folder with an original copy of winntbbu.dll I followed the guide through using resourcetuner. I then saved the winntbbu.dll to the new folder. I then ran cmd and used makecab to compress the winntbbu.dll into winntbbu.dl_ I then copied the new winntbbu.dl_ file into the I386 folder and it asked to overwrite the old one and I said yes. I then ran setup.exe and the setup screen was still the original one. In the guide it says not to overwrite the winntbbu.dll. I thought what the heck and overwrote it using the new winntbbu.dll file. I then ran setup again and this time the setup screen was the new one. This I don't get, the guide says not to overwrite the winntbbu.dll and I did and it worked Can someone please explain if this is right or did I stuff something up. Thanks, Dare2001
