I performed the creation of a new partition into the internal HDD of my desktop computer.
The original 3 partitions of this HDD contain the Linux Ubuntu Studio 15.10 operating system, the swap partition and my personal data. The new partition contains Windows 7 Ultimate, now.
The Ubuntu, Swap and Windows partitions are primary partitions. My data partition is an extended partition.
My problem is when I put the computer ON: I can not to choose, I don't have a dual boot menu at the computer starting moment and, now, I just can enter into Windows 7.
What's wrong here?
What's happened with Ubuntu Studio?
How can I build the Dual Boot Menu?
