My laptop HDD broke. I bought new HDD. I is Asus n53sv so I dont have Windows 7 installation DVD, I had only the preinstalled Windows7 and I have product key. Since the hdd is unusable I must download new Windows7 ISO. I am trying to download it from here: microsoft.com/en-us/software-download/windows7 and i put product key there and it says Error: The product key you entered appears to be for software pre-installed by the device manufacturer. Please contact the device manufacturer for software recovery options.

I've downloaded Win7 ISO not from MS pages, I check its veracity and I have doubts: The Win7ISOVerifier says that: The specified ISO file is not recognized Windows 7 image. I installed it on USB HDD and it boots OK but before using it I must check its veracity.

Where are the ISO checkums to check? Why Win7ISOVerifier doesnt recognize it?

  • Here's your problem: "I've downloaded Win7 ISO not from MS pages". Unless you get it from MS (or a trusted supplier) you shouldn't trust it's genuine. So why not go get it from Microsoft directly? – Ƭᴇcʜιᴇ007 Dec 23 '15 at 16:20
  • I updated the post, there is a reason why not MS pages. I have one last idea - I also have Acer laptop with Win7 also preinstalled. There is a system recovery DVD which I could create and install that Windows7 on my laptop and provide my product key. Is it a good solution, do u have any better? – user1308908 Dec 23 '15 at 16:22
  • You're probably going to have to get a new license anyways, so you might as well go get one, then go back to Microsoft for the Win7 download. That's the best way to make sure everything is good. – Scott Marlin Dec 23 '15 at 16:27

    Perhaps do as it suggests and contact Asus and enquire about getting install DVDs from them? – Ƭᴇcʜιᴇ007 Dec 23 '15 at 16:31

    The SHA1 checksums are on MSDN. Give me the full name of the version it's supposed to be (32bit, 64 bit, home, pro, N, K, ...) and I can check. – Sacha K Dec 23 '15 at 17:30

If you're concerned, download it from the Microsoft website. It's not hard for someone to modify an ISO to add whatever they want to it and still have it fully functional, so be warned if not using a genuine site.

Note also that Win7IsoVerifier is unlikely to have been maintained to cover all distributions out there now, so isn't necessarily a problem...

From Win7ISOVerifier site (dated 2009):

Update 3: With the wider public release of Windows 7, this tool is no longer kept up to date with the many and numerous versions of Windows 7 SKUs and languages. It is recommended you take personal care when using any ISOs.

  • He's right - the Verifier is not updated anymore, so new versions wouldn't be covered. – Scott Marlin Dec 23 '15 at 16:25
  • Where is the MS website for download? Only one I've found asks me for product key and then error appears before download, just like I quoted in the first post. – user1308908 Dec 23 '15 at 17:42
  • Microsoft only has downloads for retail versions of Windows, they took down all the oem download links long ago. – Moab Dec 24 '15 at 18:54

As far as I know, Win7 ISO Verifier only works correctly for English versions. So you may have a non-English version that is perfectly fine, but the Verifier won't recognize it.

Also, in regards to your license key: The OEM key probably won't work on a new install of Windows. You'll likely need to purchase a new license key (which Microsoft is no longer selling, so you'll have to go through a 3rd party).

  • Its EN version however I've noticed 2009 note, saying that it is no longer kept up to date.. – user1308908 Dec 23 '15 at 17:47
  • OEM keys do work on Windows 7 systems as long as it's the same edition. – conquistador Dec 24 '15 at 8:04
