I've searched and read like 100 topics without finding a solution...feeling frustrated. At first all the important system specs: WinXP Home OEM SP2 nLite v1.2 RC Installing nLited OS from another XP installation using command line "winnt32 /s:[path_to_I386_folder] /unattended0:[location_of_winnt.sif]" My primary master disk has several partitions. Boot partition C as well as few other partitions have already XP's installed. What I'd like to do is to have XP installed on the partition without previous OS installations. Now that I try to make an unattended install, Windows setup always starts automatically installing on the C partition. I never get the dialog to choose the partition to install on. All the partitions I need already exist and are formatted. I'd just like to have a chance to select the partition. Here's my winnt.sif: ; Generated by nLite 1.2 RC [Data] Autopartition=0 FloppyLess=1 MsDosInitiated=0 UnattendedInstall="Yes" [Unattended] UnattendMode=DefaultHide UnattendSwitch="No" OemPreinstall="Yes" OemSkipEula="Yes" ComputerType="Advanced Configuration and Power Interface (ACPI) PC", Retail FileSystem=* WaitForReboot="No" NoWaitAfterTextMode=1 NoWaitAfterGUIMode=1 DriverSigningPolicy=Ignore NonDriverSigningPolicy=Ignore Hibernation="No" Repartition=No [Display] Xresolution=1280 Yresolution=1024 BitsPerPel=16 Vrefresh=75 [GuiUnattended] AdminPassword=* TimeZone=125 OEMSkipRegional=1 OemSkipWelcome=1 [Shell] CustomDefaultThemeFile = "%WinDir%\Resources\Themes\Custom.theme" DefaultThemesOff="Yes" DefaultStartPanelOff="Yes" [Components] [UserData] ProductKey="XXXXX-XXXXX-XXXXX-XXXXX-XXXXX" ComputerName=AUDIOKONE [RegionalSettings] LanguageGroup=1 Language= "040b" [Networking] InstallDefaultComponents="Yes" I also have a problem with custom theme. I've set things up exactly as instructed at http://unattended.msfn.org/unattended.xp/view/web/76/ but somehow Windows setup complains about missing file "Custom.the" during copying files. It might be $OEM$ folder is ignored for some reason. I'll have to confirm that... And finally, even though WaitForReboot is set to No I still get 15-second counter asking me to wait or reboot manually by clicking the corresponding button.
