Hey, So recently my computer wouldn't start up and was saying "BOOTMGR IS MISSING | PRESS CTR+ALT+DEL TO RESTART" and then I just left the computer on for a couple days and forgot about it. And just an hour ago I started it up again just seeing if it would work, and it did. It started up and I was really happy. But I got a D-Link wireless network adapter that I connect to the tower because I can't get an Ethernet cable to reach up stairs, So I have to connect to my wi-fi. BUT when I click on "Connect to a network" nothing happens. I can't Set up a new connection or network, and when I click on the network icon on the bottom bar nothing happens. I do NOT have the Windows 7 Ultimate Repair DVD. So I can't use that. Please help!
