I need to do a full OS reinstall for my Studio 1558 to Windows 7, but have lost the CDs that came with it. Looking at the Dell support pages, that ISO is no longer available. Is there any way that I can get hold of them? I have the licence key (it's on a sticker on the bottom of the laptop), so don't need to worry about that.
Or as long as you have the product key that came with your system, you could download a Windows 7 ISO file directly from Microsoft and then either burn it to disc or use it to prepare a bootable USB flash drive that will install Windows: www.microsoft.com/.../windows7
