I made my unattended install cd. I started it up, and it stopped at the "Installing Windows" part. The exact error is... I've read the required MS KB article, but when i push Shift+F10, and type regedit.exe I get this error... I put in the original OS CD, and pointed the path to where the asms folder is, and it wont work still. The only problem I can think of, is in my WINNT.sif file on my unattended install CD, I only have the name for my SATA RAID HD, as 'OEM', and I dont have any IDE controllers as 'Retail'. Here is what my Winnt.sif looks like. [Data] AutoPartition=0 MsDosInitiated="0" UnattendedInstall="Yes" [Unattended] ActivateProxy=Proxy AutoActivate=Yes DriverSigningPolicy=Ignore OemPnPDriversPath="Drivers\Gigabyte" OemPreinstall=Yes UnattendMode=FullUnattended UnattendSwitch="yes" OemSkipEula=Yes TargetPath=\WINDOWS WaitForReboot=No [OEMBootFiles] TXTSETUP.OEM IASTOR.CAT IASTOR.INF IASTOR.SYS [MassStorageDrivers] "Intel(R) 82801ER SATA RAID Controller" = "OEM" [GuiUnattended] AdminPassword=* EncryptedAdminPassword=NO OEMSkipRegional=1 TimeZone=3 OemSkipWelcome=1 [UserData] ProductKey=12345-67890-abcde-fghij FullName="me" OrgName="" ComputerName=Squeeze [Display] BitsPerPel=32 Xresolution=1280 Yresolution=1024 [Identification] JoinWorkgroup=WORKGROUP [Networking] InstallDefaultComponents=Yes [Components] Accessopt=off AutoUpdate=off Clipbook=off deskpaper=off dialer=off fax=off freecell=off fp_extensions=on hearts=off hypertrm=off iis_common=on iis_inetmgr=on iis_www=on iisdbg=on media_clips=off media_utopia=off; minesweeper=off; msmsgs=off msnexplr=off netoc=off pinball=off rec=on solitaire=off spider=off templates=off vol=on zonegames=off [Shell] DefaultStartPanelOff = Yes I started the formatting of a full install from an original CD, then I got called into work. So i'm 99% sure its gonna be able to get back up and running. What I think the problem is, is my [MassStorageDrivers] section, I think I need the device name for my IDE cdrom drive. Can someone verify this for me? Or point me in the right direction? I used Pure Krome's method Here
