Ok… so you lost your Windows 7 install disk…
well as luck would have it…. below is a list of direct downloads .. of course you will still need to have a valid key, but if you are doing a re-install then a quick jellybean or look at the sticker on your machine and your away..
All of the downloads are circa 2gb in size so its no doubt a good idea to get somewhere with a good internet link and a download manager to make things run smoothly…
Download Windows 7 Ultimate 32-bit x86 ISO
Download Windows 7 Ultimate 64-bit x64 ISO
Download Windows 7 Home Premium 32-bit x86 ISO
Download Windows 7 Home Premium 64-bit x64 ISO
Download Windows 7 Professional 32-bit x86 ISO
Download Windows 7 Professional 64-bit x64 ISO
Download Windows 7 SP1 Integrated ISO
yes I put both up as some people prefer the original…
