Currently i have 2 partitions Partition1: NTFS, winxp is currently installed here Partition2: Data, Music in my WINNT.SIF I have this: [Data] MsDosInitiated="0" UnattendedInstall="Yes" AutoPartition=1 Will this: -format partition 1 into NTFS -Install winxp on this Partition? I already created a ISO, but i'm afraid to burn & use it. (I don't want to lose all my data! very important!!! ) Or can anyone give me the right stuff to put under [data]? thanks!
