Hi, I try to make a WinPE bootable solution for a Workstation master. My problem is the size of my CD 1,3 Giga (Drivers, Winxp, WinPE...). I would like to slip my data in 2 CDs. First CD with WinPE boot and WinXP. I boot on WinPE I create my unattend file with HTA Files At the end of the install I launch Build.cmd to create folder and copy WinXP folder locally. Then, I want to remove my bootable CD1 and insert my CD2 and copy all files on my hard disk. I launch robocopy from my hard disk to copy file from my CD2. But It doesn't work !! Please some help. BUILD.CMD Echo **** Create FOLDER **** md C:\I386 md C:\XPMUI md C:\I386\$OEM$ Echo **** Copying Postconf files from CD 1 **** xcopy /e /y %systemdrive%\WINXP\I386\*.* C:\I386 Echo **** Change CD **** Call C:\TEMP\CONFIG\CDASK.CMD Echo **** Copying Postconf files from CD 2 **** c:\TEMP\CONFIG\ROBOCOPY /e D:\WinXPMUI\*.* C:\XPMUI c:\TEMP\CONFIG\ROBOCOPY /e D:\$OEM$\*.* C:\I386\$OEM$ Echo ************ launch XP install c:\I386\winnt32.exe /noreboot /syspart:c: /s:c:\I386 /unattend:c:\temp\config\unattend.txt CDASK.CMD CScript C:\TEMP\CONFIG\CDASK.VBS :END CDASK.VBS Option explicit Dim fso, Reponse Set fso = CreateObject("Scripting.FileSystemObject") Do Until (fso.FolderExists("D:\$OEM$")) Reponse = msgBox ("CD1 installation finished" & chr(13) & "Please insert CD2",,"CD change") Loop WScript.Quit
