Hi everyone, Here is my script that does the job of the original BootSectGui. I wrote it because I needed a BootSectGui that works in WinPE x64 environment. The original works only in x86 envoronment. It is free to use, modify and distribute. I coded first in French and then in English, it may have some mistranslation. In the 7z attached file you have these files: BootSectGui - original - Main.png -> The original Main window of BootSectGui BootSectGui - original - Log.png -> The original Log window of BootSectGui BootSectGui - original.exe -> The original BooSectGui.exe program BootSectGui_x86_x64.au3 -> My code BootSectGui_x86.exe -> My program x86 version 1.3 BootSectGui_x64.exe -> My program x64 version 1.3 BootSectGui_x86_x64 1.2.1.au3 -> My code for 1.2.1 BootSectGui_x86 1.2.1.exe -> My program 1.2.1 x86 version BootSectGui_x64 1.2.1.exe -> My program 1.2.1 x64 version BootSectGui_x64 - Main.png -> My Main window BootSectGui_x64 - Log.png -> My Log window BootSectGui_x64 - Main 1.2.1.png -> My Main window 1.2.1 BootSectGui.psd -> My "code" for the ico files in Photoshop format BootSectGui BSG 64.ico -> The icon used with my program, in 64 dots BootSectGui BSG 256.ico -> The same in 256 dots BootSectGui G BS 64.ico -> Another icon that looks more like the original one, in 64 dots BootSectGui G BS 256.ico -> The same in 256 dots Enjoy!

Hello everyone. 3 days back, I came across "El Torito" Bootable CD-ROM Format Specification. I was able to write this simple script to extract Boot-Image from a CD/DVD/ISO file. Here is it: #include <WinAPI.au3> Global $nBytes ConsoleWrite("Boot-Image X-tract (by MKISH)" & @crlf & @crlf & "USAGE: bootext.exe <PATH> <IMGNAME>") If $CmdLine[0] = 0 then Exit If NOT FileExists($CmdLine[1]) then Exit $PATH = $CmdLine[1] $RESULT = $CmdLine[2] $hFile = _WinAPI_CreateFile("." & $PATH, 2,2) $xBuffer = DllStructCreate("byte["& 4 & "]") _WinAPI_SetFilePointer($hFile, 0x11*0x800 + 0x47) _WinAPI_ReadFile($hFile, DllStructGetPtr($xBuffer), 4, $nBytes) $sText1 = DllStructGetData($xBuffer, 1) $dBuffer = DllStructCreate("byte["& 4 & "]") _WinAPI_SetFilePointer($hFile, 0x800 * Int($sText1) + 0x20 + 0x8) _WinAPI_ReadFile($hFile, DllStructGetPtr($dBuffer), 4, $nBytes) $sText2 = DllStructGetData($dBuffer, 1) $fBuffer = DllStructCreate("byte["& 1 & "]") _WinAPI_SetFilePointer($hFile, 0x800 * Int($sText1) + 0x20 + 1) _WinAPI_ReadFile($hFile, DllStructGetPtr($fBuffer), 1, $nBytes) $sTextd = DllStructGetData($fBuffer, 1) $pBuffer = DllStructCreate("byte["& 2 & "]") _WinAPI_SetFilePointer($hFile, 0x800 * Int($sText1) + 0x20 + 0x6) _WinAPI_ReadFile($hFile, DllStructGetPtr($pBuffer), 2, $nBytes) $sText3 = SecCount() $zBuffer = DllStructCreate("byte[" & $sText3 * 0x200 & "]") _WinAPI_SetFilePointer($hFile, 0x800 * Int($sText2)) _WinAPI_ReadFile($hFile, DllStructGetPtr($zBuffer), $sText3 * 0x200, $nBytes) $sText4 = DllStructGetData($zBuffer, 1) FileWrite("" & $RESULT, $sText4) _WinAPI_CloseHandle($hFile) Func SecCount() $fBuffer = DllStructCreate("byte["& 1 & "]") _WinAPI_SetFilePointer($hFile, 0x800 * Int($sText1) + 0x20 + 1) _WinAPI_ReadFile($hFile, DllStructGetPtr($fBuffer), 1, $nBytes) Switch DllStructGetData($fBuffer, 1) Case 0x00 Return Int(DllStructGetData($pBuffer, 1)) Case 0x01 Return Int(0x50 * 0x02 * 0x0F) Case 0x02 Return Int(0x50 * 0x02 * 0x12) Case 0x03 Return Int(0x50 * 0x02 * 0x24) EndSwitch EndFunc Just compile this as CUI App. Hope it is of use to somebody. Useful suggestions are welcome. EDIT: The link is working now. A bugfix
