SUMMARY
By default, Windows NT Setup preserves the existing file system. Moreover, it is not possible to convert an existing partition from the Windows NT file system (NTFS) to a file allocation table (FAT) file system. However, it is possible to automate the process of converting a FAT partition to NTFS during an unattended installation or by using Computer Profile Setup.



Unattended Setup
This method uses WINNT.EXE or WINNT32.EXE with the /U switch and an answer file. To make the necessary modifications:

WARNING: Modification of INF files can cause serious, system-wide problems before and after Setup and may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the modification of INF files can be solved. Make INF modifications at your own risk.

 Copy the I386 directory from the Windows NT compact disc to your hard drive. Expand I386\INITIAL.IN_ to I386\INITIAL.INF Rename I386\INITIAL.IN_ to I386\INITIAL.BK_  In the SetAcls section of INITIAL.INF, change the line "set Convert_Winnt = $($1)" to "set Convert_Winnt = YES" as is shown in the following excerpt:

     [SetAcls] set Status = STATUS_FAILED set Convert_C    = $($0) ;;; Setting the below variable to YES forces NTFS Conversion set Convert_Winnt = YES  Save INITIAL.INF and close the file. Run Unattended Setup.</li></ol>

Computer Profile Setup
Include "-f:n" on the UPLODPRF.EXE command line.

For complete syntax, type UPLODPRF.EXE /?.
