After some digging and additional batch scripting, I have developed a working solution for the CD/DVD drive letter changing when the computer reboots from GUI mode setup to first login. The link below has the original thread http://www.msfn.org/board/index.php?showtopic=74179 Two additional script files are included and they are copied over to the HD from the DVD during text mode setup using the $OEM$ directory structure. The sequence of execution is as follows:

  1. cmdlines.txt
  2. WINSETUP.CMD
  3. SYSTEM-ANALYZE.CMD
  4. SYSTEM-CONFIGURE.CMD
  5. SYSTEM-INSTALL.CMD

--OR--

If the CD/DVD drive is D:, then the following sequence is executed:

  1. cmdlines.txt
  2. WINSETUP.CMD
  3. SYSTEM-ANALYZE.CMD
  4. SYSTEM-INSTALL.CMD

WINSETUP.CMD

This is called from cmdlines.txt and runs at T-12 during the GUI mode setup phase. This determines what the current CD/DVD drive letter is, checks for the test environment, and then calls %SYSTEMDRIVE%\tmp\SYSTEM-ANALYZE.CMD

@ECHO OFF

REM Check the command line argument.  If nothing is given, then we are going to do a
REM live install from the DVD-ROM.  If TST is given, then we are in the test
REM environment on the harddisk and the base path is different.

IF /I "%1"==""	GOTO :START
IF /I "%1"=="TST" GOTO :TEST
GOTO :ERROR

REM This is the DVD-ROM Installation
:START
REM Hide the command window
CMDOW @ /HID

REM Find our CD-ROM Drive and set the evnironment variable

REM Set our base DIR and call the main system script.

GOTO :EOF

REM This is only called if there is a command line argument error
:ERROR
ECHO Command Line Error
ECHO Valid Options are nothing and TST for install and test
GOTO :EOF

SYSTEM-ANALYZE.CMD

This checks the current CD/DVD drive letter. If the letter is not D:, then it will initiate a two stage reboot to allow windows to reorder the drive, otherwise it will just simply call %CDROM%\INSTALL\SCRIPTS\SYSTEM-INSTALL.CMD which will load the RunOnceEX reg key with the run data to install everything. This is one of two files that are copied to the HD at %SYSTEMDRIVE%\tmp.

GOTO :EOF

SYSTEM-CONFIGURE.CMD

After the reboot caused by SYSTEM-ANALYZE.CMD, this script runs to analyze what the current CD/DVD drive letter is and then calls SYSTEM-INSTALL.CMD to load RunOnceEX with the data necessary to install everything. This is the second of two files that is installed onto the HD from the $OEM$ file structure during text mode setup.

Dude, there must be a waaaay simplier method

You know, when I run Windows Setup on a new harddisk, create 2 partitions, after install/setup etc the partitions will be C: and E: and CD drive is D:

Ofcourse I want the partitions to have the first letters so I turn off PC,

pull out the CDdrive flat cable, turn on PC, in Windows you will now see the 2nd partition has become D: drive since that letter is free :)

Shutdown pc, flat cable back, turn on pc. Now cddrive is E:.

If you don't want to remove the flat cable, System Management (actually I dont know how its called in English, I mean Start>Run.. MMC.exe)

you can give the CD Drive a different letter like X:.

now the D:\ has become available, so you can give the 2partition this letter.

Now the E: letter has become available, so you can give the CDDrive this letter.. and I am sure this method in a script would be easy..

But it isnt what I want, I rather mod the windows Setup to prevent it from doing it like this. Don't know how..
