I have a dell inspiron 1501 laptop running windows vista. I would like to format the hard drive and bring the computer back to its original condition. I do not have a copy of the operating system on a cd but there is a partition on the hard drive labeled "recovery" The manual I have tells me to hold down the <ctrl> and <F11> keys at boot up when I see www.dell.com appear. I have tried this several times but it does not work. Is there another way?
