My brother has sent me his HP laptop which has blown it's hard drive , he doesn't have any recovery media. I posted on the HP forum for a link for an iso as the Microsoft website told me to approach the manufacturer. Here is the answer
You cannot. HP has no .isos for download. Microsoft used to publish Windows 7 OEM .isos on its "digital river" site until maybe just under 2 years ago when they took it down. You can look on eBay and maybe just online for a recovery disk for your specific model which you see for sale for maybe $40, or you can take a walk on the wild side and look for Digital River mirror sites for Windows 7 .isos. They are out there and for the most part trustworthy but they are not official and Microsoft does not like us to post specific links for you.
This I can understand it is disappointing as it is completely legitimate what I am trying to, the product key on his machine is read-able and I wish just to get it up and running. Has anyone any pointers, without of course , crossing any lines or rules.
