I recently purchased a Lenovo x201t laptop/tablet from a friend of mine for a killer price. It has 8GB of DDR3 RAM, an Intel Core i7 processor, etc... It is just a really loaded laptop but it is hanging all the time, crashing, etc... So I want to do a fresh install.
Unfortunately, this laptop does not have an o9ptical drive but I did follow instructions to copy all my Windows 7 installation media to a USB key and I will use that for the installation, but I have two things I need to sort out before I can begin and I can't seem to figure it out myself.
The laptop is currently running Windows 7 Ultimate, x64.
1) The laptop shipped with an OEM Version of Windows 7 Professional and there is a COA sticker on the bottom of the laptop with a product key on it, I'm assuming I could use this if I were to download an OEM Windows 7 Pro x64 install DVD and put it on the thumb drive, but I really want to use Windows 7 Ultimate as that is what is on the laptop now.
I used Belarc Advisor to print out a complete configuration of my hardware configuration so I can be sure I get everything reinstalled properly and it was also able to pull out the product key for my current Windows 7 Ultimate installation, that I assume I can reuse but that is what brings me to my second problem...
2) I'm not sure of installation method that my buddy used to install Windows 7 Ultimate x64 on this machine and I can't get a hold of him for a few weeks as he is out of the country and away from any computer/iPad/Blackberry/etc... So I figure he had to do one of three things; 1) Purchased Windows 7 Ultimate Upgrade and upgraded the Windows 7 Pro installation that was already installed 2)He could have used an OEM version of Windows 7 Ultimate x64 to do the new installation or 3) He could have purchased Windows 7 Ultimate x64 from a local retailer or online and did a complete clean install with a full retail version of Windows 7 Ultimate x64.
How can I figure out which type of media my product key is valid for? I'm sure there must be some way to figure this out, but I can't seem to find that information anywhere and I thought if anyone knew, it would be you guys!
Please let me know if I'm missing and information or if I can provide more information to help me solve this puzzle.
