I am trying to achive an unattended installation of Windows XP with SP2 What I want to do is to PXE-boot to an Windows PE v2, unattended partition and format the harddidsk and then install Windows XP unattended. But the unattended partition and formating of the disk fails. I am using Diskpart. My commands basicly looks like this. [startnet.cmd] drvload x:\windows\lan\netamd.inf wpeinit net use z: \\server01\reminst /USER:[My username] [My password] x:\windows\system32\Wscript.exe z:\Share\Scripts\install.vbs [install.vbs] Set WshShell = WScript.CreateObject("WScript.Shell") WshShell.Run "diskpart /s z:\Share\Scripts\disk.txt", 1, True WshShell.Run "CMD.exe /C echo y | format C: /FS:NTFS /Q /V:System", 1, True WshShell.Run "CMD.exe /C z:\Share\I386\winnt32.exe /syspart:c: /s:z:\Share\I386 /unattend:z:\Share\unattend.txt /copysource:lang", 1, true [disk1.txt] select disk 0 clean create partition primary select partition 1 active assign letter = C The installation starts and after the first boot I get the error A disk read error occurred Press Ctrl-Alt-Del to restart Can anyone help me with this one?! I have tried a numbers of different ways, but nothing seems to work.
