You are OK., only laptops have MD.
Hi    I want to restore my pc to how it was when i received it and i looked in the manual and online how to do this but found when i use the F8 option and go to Repair Pc I do not have a Dell factory Festore option or any other Dell options. I also tried the Ctrl + F11 mentioned in another post but this did not work either. As i said i have not touched the D:\ Recovery partition that i see in my computer. Please advise how to complete this operation or with any other advice thank you my system is Studio XPS 435MT Intel Core i7 970 2.67ghz 4GB ram 64 bit windows vista
