Hi, i was wondering which of the 3 available methods would be the best when installing windows from a distribution folder via network - ie. not using any cdrom. The distribution share is only available prior to installing windows for copying the files, it is not restored later. I don't fancy using method 1. Method 2 wouldn't work for obvious reasons, because it places files in the root of the cd/dist. folder. Method 3 worked for me when i copied the 7za.exe from the OEM/bin folder to $OEM$\$1 and edited my unattend.txt file with the entries made to winnt.sif, but then i was going through the batch files and found this section in BTS_DPs_finish.cmd: :KtD_M2M3 SET tagfile=\I386 FOR %%i in (c d e f g h i j k l m n o p q r s t u v w x y z) do if exist "%%i:%tagfile%" set CDDRIVE=%%i: IF NOT EXIST %CDDRIVE%\I386\presetup.cmd GOTO KtD_M1 IF EXIST %DPDIR%\SetupCopyOEMInf.exe ( START %CDDRIVE%\OEM\bin\WatchDriverSigningPolicy.exe START /WAIT %DPDIR%\SetupCopyOEMInf.exe %DPDIR% TASKKILL /F /IM WatchDriverSigningPolicy.exe ) ELSE ( %CDDRIVE%\OEM\bin\SetDevicePath.exe %SystemRoot%\Inf ) GOTO Cleanup Which (if i get it right) won't work in my case, effectivelly skipping to the KtD_M1 section? It doesn't seem to have any side effects, but i would like to know if there's some easy modification for usage with distribution folders. Thanks for any input.
