Can it be set to not do anything but change the letter, ie. still let me select the partition to install on? The settings seems to be for selecting the partition to install on too. It would feel a bit safer to select the partition yourself the first time. Also, I don't know what DiskID and PartitionID my specific partition is. In Diskmanager (or whatever it's called in the english version of XP) the disk is called "Disk 2", which I guess is the same as the DiskID but the number for the partition is not listed. EDIT: Would leaving them blank do just that? (I ask all these questions before trying it out, in the hopes that you are still there, since Microsoft's download server crapped out on me and for some reason only let's me download the files in 40kb/s instead of the usual 3000-3500kb/s. It meant I had to ask a friend to download them and then upload to me.) EDIT 2: Should I select "Modify" as the action to both Disk and ModifyPartition?
