I successfully recovered my laptop when I used the "Dell DataSafe Backup and Recovery" feature that allowed me to reset the device back to its factory state. Thanks again, everyone, for helping :)
I want to format my laptop, but there is a problem -- I lost the OS disk for it. I have all the information located at the Microsoft label found at the back of the laptop, but I do not know what to do with it. Please help?p.s. It is a Win7 Home Premium x64
Where do I get an OS for my Dell Inspiron 15R N5110 (Early 2011) ?
