I used an OEM full-version Windows 7 pro disk to do a clean install (not upgrade) over windows vista home premium. Everything is fine except now there are two lines in the boot manager. The first is Windows 7 and the second is Windows Vista Home Premium (recovered). This computer was purchased from a system builder (Ibuypower), but as far as I know there was no hidden recovery partition. I've deleted windows.old and checked disk management and no "extra" partitions are visible. I'm sure I can edit the boot manager to remove this second entry, but does anyone know why it is there? What does it mean by "recovered"?
