Hi, I've made a simple XP SP2 unattended install that installs a few other apps after XP. These include Office 2003, NAV, Sygate Personal Firewall I have tested the image file i created using the CDImage tool from MSFN's guide. The VMware virtual machine worked perfectly without out fail. However when I try are run the installation on my PC, the text mode setup runs as usual, copies the files and resets as normal. When the computer reboots, the boot menu appears and I select the new XP (I dual boot with an old XP on a second seperate drive) The screen goes black and the computer freezes. First thing I did was to go into safe mode and watch to see where the computer stopped. I noticed that it was mup.sys which was the last item to appear on the screen before it hanged. I think that either mup.sys is the problem or the file that loads after mup.sys So I disabled mup.sys with the disable mup command. This didn;t solve the problem. I have installed XPSP2 with the same image manually just with the winnt.sif file removed. I had no problems. I'm stuck for ideas because I don't any strange hardware. the original setup did use a seperate kernel but i removed that with the same problem. Any Ideas? Here is my winnnt.sif file ;SetupMgrTag [Data] AutoPartition=0 MsDosInitiated="0" UnattendedInstall="Yes" [Unattended] UnattendMode=FullUnattended OemSkipEula=Yes TargetPath=\WINDOWS OemPreinstall=Yes UnattendSwitch="yes" FileSystem=* [GuiUnattended] AdminPassword=6a57cd9466e87d89aad3b435b51404eef05822fa2a7b7166af98cf16cfa5ffdf EncryptedAdminPassword=Yes OEMSkipRegional=1 TimeZone=260 OemSkipWelcome=1 [UserData] ProductKey=AAAAA-AAAAA-AAAAA-AAAA-AAAAAA FullName= OrgName= ComputerName= [Display] BitsPerPel=32 Xresolution=1024 YResolution=768 Vrefresh=60 [RegionalSettings] LanguageGroup=1 Language=00000c09 [Identification] JoinWorkgroup=MILKYWAY [Networking] InstallDefaultComponents=No [NetAdapters] Adapter1=params.Adapter1 [params.Adapter1] INFID=* [NetClients] MS_MSClient=params.MS_MSClient [NetServices] MS_SERVER=params.MS_SERVER [NetProtocols] MS_TCPIP=params.MS_TCPIP [params.MS_TCPIP] DNS=No UseDomainNameDevolution=No EnableLMHosts=Yes AdapterSections=params.MS_TCPIP.Adapter1 [params.MS_TCPIP.Adapter1] SpecificTo=Adapter1 DHCP=No IPAddress=192.168.1.3 SubnetMask=255.255.255.0 DefaultGateway=192.168.1.1 DNSServerSearchOrder=192.168.1.1 WINS=No NetBIOSOptions=0 [Components] Msnexplr = Off Msmsgs=off Zonegames = Off [WindowsFirewall] Profiles = WindowsFirewall.TurnOffFirewall [WindowsFirewall.TurnOffFirewall] Mode = 0 [Shell] CustomDefaultThemeFile="%Systemroot%\Resources\Themes\MetallicShades.theme" Am I correct in asumming that my problem has nothing to do with my RunOnceEx.cmd file because it won't have been executed yet because the GUI setup stage has not yet run? Thanks
