Hi Jaclaz, Happy to see you here, I have read many thread where you post something around this problem. I ve not watch at migrate.inf and hope this solution will help me. My main goal is to install XP and 2K3 on the same disk with XP on C: and 2k3 on D: and have "Program Files" and "Profiles" on another disk E: BUT.... The disk for XP and 2K3 is manage by the onboard controller (NVidia) The disk for the "PFiles" and "Profiles" is managed by a PCIe contoller The actual configuration give this result in diskpart: (I have not convert all my partition in extended one) Controller | Volume | Disk | Label | Partition Number | Partition Type Lsi | D: | Disk 0 | PFiles | Partition 1 | Primary Partition NVIDIA | C: | Disk 1 | XP | Partition 1 | Primary Partition NVIDIA | E: | Disk 1 | 2K3 | Partition 2 | Primary Partition With other HD attach to NVidia controller, each with primary partition. I know, I will have to make modification on my partition, but for now, I'm trying to determine if I can do my install the way I want or not, so I'm using VM to test... Thanks for your assistance Jaclaz
