CLASYS Posted October 9, 2015 Share Posted October 9, 2015 Hi folks! I haven't been here in quite awhile [because I got all my problems solved here!]. But of course there is always one more: I am attempting to install Win7 on a Lenovo W540 w/8GB and the 2.70 CPU. I can run 8.1 on it fine,and I have also installed Vista [although many driver problems, but I still got it up enough to have it proclaim "genuine software". I can install the product key [that matches the Windows version] fine. But I cannot install the cert file LENOVO_V2.1_Cert.XRM-MS and get the error code 0x00000BBA The spool file was not found. Is this somehow related to the fact that the Win8/8.1 key is built into the BIOS? Do I need a[n even] new[er] Cert file? All else is fine, but only got about 3 weeks more to activate. Any help appreciated. Link to comment Share on other sites More sharing options...
Kelsenellenelvian Posted October 9, 2015 Share Posted October 9, 2015 You have to activate. We don't do things that way here. Link to comment Share on other sites More sharing options...
Tripredacus Posted October 9, 2015 Share Posted October 9, 2015 You should be using the Lenovo recovery media to install Windows 7 and not some other source. Is this somehow related to the fact that the Win8/8.1 key is built into the BIOS? No. Link to comment Share on other sites More sharing options...
Radish Posted November 10, 2015 Share Posted November 10, 2015 (edited) What you are trying to do is perfectly legal. I did this myself on my own Win7 system - replaced an OEM install of Win7 (which was a horrorshow) with my own install of Win7 (much better by a long margin) using the 'Product ID' and the 'Cert' pulled from the OEM install. All perfectly legal - I wouldn't have done it otherwise. Try this forum, they specialise in this kind of thing. You can get tools to help you in what you want to do. However, by my reading of your post you sound as though you may be dual booting different versions of Windows. But I only think that is what you're saying. If you post elsewhere you need to be very clear and logical in explaining the setup of your machine and what exactly it is you're trying to do.

submix8c Posted November 10, 2015 Share Posted November 10, 2015 (edited) Dangerous grounds, there, radish. We're fully aware of MDL. If the OP has obtained files from other than their own install, we can't help here AT ALL!http://shop.lenovo.com/us/en/laptops/thinkpad/w-series/w540/Tech Specs -OS - Windows 8.1 Pro 64, Windows 8.1 64, Windows 7 Professional 64One wonders what originally came on it? Sounds like Win8, since it seems to be "locked in"?OP may look into a Lenovo Downgrade from... Lenovo. Side note - searching on the Error Code shows some interesting results.

Tripredacus Posted November 10, 2015 Share Posted November 10, 2015 OP may look into a Lenovo Downgrade from... Lenovo. Downgrades are at the time of purchase. In order to do a downgrade after the fact, the entire system would have to be returned to the effect that it was purchased with the wrong OS installed. Downgrades after the fact (of which I am uncertain why MS even decided to write rules for) are totally in the hands of the end user. Link to comment Share on other sites More sharing options...
