Hello All, Seeing as though this is my first post on "My Digital Life Forums", I assume that most of you don't trust me. However, I do have a valid question, one that I will try to explain as in-depth as possible, with plenty of background information to help you help me. First off, I would like to say that I did do a search on this subject. Yes, there are hundreds of threads exactly like this one, but from my standpoint (an inexperienced one in these matters), none of them seem to fit my exact situation. So, I recently installed an mSATA solid-state-drive into my Lenovo Y580. This new laptop originally had Windows 8 64-Bit installed on its stock, 900GB+ and 5400rpm hard-drive. This hard-drive, as you will see soon enough, is still installed in my Laptop and still has Windows 8 64-Bit on it. After installing the mSATA, I needed an operating system. I heard that mSATA SSDs work best with Windows 7, so that is exactly what I went for. I downloaded a Windows 7 Ultimate 64-Bit .iso from DigitalRiver, burnt the .iso to a CD, and then did a full-install of Windows 7 onto my mSATA SSD. After installing Windows 7 on the SSD, I tried to activate Windows 7 immediately, but I received the same error then as I do now - "Unsupported partition table". I didn't think this was of any significance, so I haven't bothered activating my Windows until now. As of this morning, I have began getting the occasional black background, and I now have an annoying water-mark in the bottom right of my screen. So, I downloaded the most recent Windows 7 loader (or at least what seems to be the most recent one), and I still get the same error. Here is my question - How do I get this Windows 7 loader to work with my Lenovo Y580? Here are a few of my system specifications and a picture of the error I receive. I am using a Windows 8 theme, because I like the designs and sounds. BECAUSE I CANNOT POST IMAGES (or links) YET, PLEASE REFER TO THIS ALBUM. I HAVE POSTED PICTURES OF MY MOTHERBOARD, MY DISK MANAGEMENT PAGE, AND THE ERROR. just add a '.' between the "imgur" and "com" imgur com/a/wNfVr#0 Thanks for your help and for putting up with such a common issue.
