hi guys, I am creating a full unattended xp,i edited the billboard using res hacker and saved it and applied the patch for disabling the windows protection, but when i install in my virtual pc,after the setup starts and starts copying the files to the harddrive, its says that the winntbbu.dll has been modified or corrupt,and says it cannot copy it to the hard drive,and i skip the copy process for that file. Pls give me a solution to solve this and i also want to know the procedure to edit the setup.exe file in the cd. Plwase mail me regarding this to my email id gameover_friends@hotmail.com. thanks in advance krishna
