Solved Booting Windows 7 on a new Mobo Tags: Memory Windows 7 Computer Hard Drives Last response: September 15, 2012 9:55 PM in Memory Share Taylor_31 September 15, 2012 4:31:18 AM So, I just built my new computer, and I used my hard drive from my old computer that had Windows 7 on it. How do I boot windows 7? Or do I have to buy it again? More about : booting windows mobo Best solution yyk71200 September 15, 2012 4:49:57 AM You need to reinstall Windows. If you had a retail version of Windows before, you just need to reinstall it and reactivate. If it was an OEM license, you need to buy new one. runswindows95 a b $ Windows 7 September 15, 2012 5:29:03 AM I agree with yyk71200. The best thing to do whenever you swap out the motherboard is reinstall the OS. There are ways to try and repair the installed copy of Windows, but from I've seen, it so much quicker and easier to reinstall.
