That's sounds correct Phurios, but I was under the impression that PE should actually be able to deal with the Drive letters as they are already known. It seems to be naming them under it's own way. It sees C: correctly and swaps D: and E: around. This I don't understand because under 2000 Server C: & D: are on the same physical disk and E: is on another physical disk. Another point is during the PE section of the install i use diskpart and select disk 0, clean it, partition and name it E: But once windows server 2003 install is complete it sees this partition as d: Unbelievable. Thanks for the reply!
