I'm not sure what i did but when i restarted my computer, it said bootmgr is missing. I've been trying to find ways to repair it. I mostly saw people saying to use a Windows 7 installation disk to start the repair service on it. I got my Windows 7 Professional from my school. I have a legit code and have installed it on my PC before. Is there any other way instead of burning a DVD/ISO? Also saw people saying to press F8 when starting up the PC but it doesnt bring me to the repair place. Help would be much appreciated!
