I already have windows installed and I just installed Ubuntu and I was expecting that it will ask me which OS to boot after startup but it didn't.
I refer the link but didn't work Windows 7 not showing up in boot after installing Ubuntu.
I set the option of Erase disk and install Ubuntu. But it says currently has no detected operating system.
How to set this option now. I already have Ubuntu installed and I am not getting option to boot windows.
