Hello.
I have done a Windows XP 2in1 (pro corp. and home) with SP1 slipstreamed. I have created the unnattended.txt file and after i have renamed to winnt.sif and put it into i386 folder.
I have two directories for each version: one for win32 installation and one for msdos.
I have made the cd booteable with menu included. And this is the problem:
all works perfectly, the installation is completely unnattended, and after this the SO works fine but....i can\'t install it on C:
I have 2 HD: one is primary master (C:) and the other is secondary slave with two partitions. I want to install it in primary master but it always go to the first partition of the secondary slave. (the install program don\'t ask for me where i want to install)
Do you know how can i do for install it in C:
This is my winnt.sif file:

simply disconnect the slave drive and do the install then reconnect the slave.

AutoPartition=0

thanks for posting!!!

i have tried to desconect the slave disk but i don\'t want that solution.I want that every computer can be installed in C without disconnect anything.
I\'ll try autopartition=0. I hope this works for me.

Autopartition=0 works fine!!!! the installation program only ask for me where i want to install it ( c:) . After that, the unnattended installation works perfectly.
Thanks for your help!!!!
