Usually before I load into an OS, I get the option menu to select Windows 7 or Recovery mode(I have thinkpadx220);
Then I used Unetbootin, which appeared as the third option. After installing Ubuntu 15.04, I don't see this option anymore it just goes straight into Ubuntu without the option for Win7, Recovery, or even Unetbootin.
I can still view all my files from Ubuntu though like Program Files and Windows folders.
I already tried this https://help.ubuntu.com/community/Boot-Repair
I made my log at https://paste.ubuntu.com/11791943/
It didn't fix it.
