Hi! I need some help. I got a cd from a *friend* with alot of SATA drivers on (starting XP CD first takes 5-10 min). Anyways, to be sure mine got included, I decided to add them. It worked fine, and so did the file copying, except for one file "Volsnap.inf", which contain this: [Version] Signature="$WINDOWS NT$" Class=VolumeSnapshot ClassGuid={533C5B84-EC70-11d2-9505-00C04F79DEAF} Provider=%MSFT% LayoutFile=layout.inf DriverVer=07/01/2001,5.1.2600.0 [ClassInstall32.NT] AddReg=volume_snapshot_class_addreg [volume_snapshot_class_addreg] HKR,,,,%VolumeSnapshotClassName% HKR,,SilentInstall,,1 HKR,,NoInstallClass,,1 HKR,,Icon,,"-53" [DestinationDirs] DefaultDestDir = 12; DIRID_DRIVERS [Manufacturer] %MSFT%=MSFT [MSFT] %STORAGE\VolumeSnapshot.DeviceDesc%=volume_snapshot_install,STORAGE\VolumeSnapshot [volume_snapshot_install] ; ; Nothing to do (these devices are raw). We just needed an INF ; match so these don't show up as "unknown" devices. ; [volume_snapshot_install.Interfaces] AddInterface={53F5630D-B6BF-11D0-94F2-00A0C91EFB8B} [volume_snapshot_install.Services] AddService = ,2,; Run the device RAW <ALOT of line breaks here> [Strings] MSFT="Microsoft" VolumeSnapshotClassName="Ögonblicksbild av lagringsvolym" STORAGE\VolumeSnapshot.DeviceDesc="Ögonblicksbild av allmän volym" So I skipped copying of this file. Next time I startup Windows (for the second install step), I get a BSoD with this code: (Yes I tried searching for it but I got nothing).Anyways, anyone know how to solve it? I will be away until next sunday if anyone wonders why I don't reply. Thanks in advance EDIT: I also added drivers I got from a DriverGuide toolkit backup, could that be the problem? (It was all drivers that were in my system, it was Vista but I'm trying to install XP) EDIT: Thanks for your help johnhc but I got round this by installing the one without my own drivers. Now it's working good
