I have a problem switching back to my windows 7. I have a dual boot system with ubuntu 14.04 LTS as main and windows 7 the other. I tried running some codes today such as
sudo apt-get update sudo apt-get upgrade and sudo apt-get dist-upgrade
After the restarting I could not find my window 7 boot option till now. When i acess the windows 7 partition it is quite empty but from disk and properties tell me that there's something on the disk. Any help to get my windows 7 boot option back. Thanks.
