lol, I'm pretty sure i didnt, i selected the C partition, deleted it, formatted it ntfs and installed windows on it - thats the disk thats still working, if id deleted the wrong partion, windows would have installed on that one, surely, and in any case the other disk is a slave not a master, and therefore I dont think its even an option.
In any case, I wouldnt have accidentally deleted all of the partitions, there were 3 of them.
