Consider installing from a USB stick for a clean setup. Avoid driver issues by using Lenovo's official tools for your E550 Thinkpad.
What are you asking? The query asked if you should reinstall Windows using a USB stick or face driver issues. Assuming you're using internet English, the question was about whether a fresh install via USB would work without problems. I answered clearly and shared useful links to tools that can help with the process.
You have options. Using Lenovo recovery disks brings extra software with it, while just the OS requires you to download programs and drivers from Lenovo’s support site yourself. When I worked with Windows using T60 (now running Ubuntu), I relied on recovery disks and cleared the bloatware manually. That approach only worked because I downgraded from Vista to XP.
