I have an Alienware M14X laptop and recently got the disk read error occurred messaged. So I purchased a new hard drive and installed it into the laptop. I then went through the whole procedure of putting an OS in and booting up the CD drive before the hard drive. I went through the whole intro for the new OS and then waited for windows to load. When it got done downloading the sign in screen that popped up was zoomed in and appeared to be in safe mode, but it wasn't in safe mode. I figured I might as well log in and see what I can do. I log in and everything appears to work normally, (even though the screen is similar to a safe mode screen) except that my laptop can't find a network to sign into the internet. The wireless connection isn't detecting my router and when I hook up an Ethernet cable directly to the computer from the modem it still doesn't recognize any network. This is my first time ever replacing a hard drive so I'm confused and can't find anything on how to fix this issue. I don't know if I did something wrong in the whole booting up process or what. Any help or advice would be greatly appreciated.
