Hi, I have this problem where a message pops up saying "reboot and select a proper boot" when I start my PC. This started when I decided to throw out my old Hard(WD Blue 500GB) drive which had windows vista on it. I bought a new Hard drive(Seagate Barracuda 1TB) with windows 7 and when I plugged in my new hard drive, I started to get this error. When I tried to use my old Hard drive I don't get the Reboot error, but instead "Windows failed to start. A recent hardware or software change might have caused the issue after you install Windows Updates" I want to use my new hard drive and windows please help!
