Hello! I installed Ubuntu 15.10 on my computer after installing Windows 7 Home Premium and decided to upgrade Windows to Pro version. Before upgrade the computer used to boot GNU GRUB and I could select the OS I want to open and now Windows boots automatically. Could you help me how to change the boot order to open GNU GRUB?  Thanks.

You're going to have to reinstall the bootloader assuming your reinstallation of windows has not wiped off Linux

You know you want me baby!

Do you still have the DVD or USB that you installed Ubuntu from? If so, in the first instance I would boot up with it, and check that your Linux partition(s) is/are still there.

 

If you need more detailed advice on how to do so, please let us know.

Boot to an Ubuntu LiveCD / LiveUSB and post the output from running this command in a terminal:

sudo fdisk -l

I have the Ubuntu DVD and I can run this Ubuntu using USB. I have a Ubuntu installed on pendrive and when I boot up from it I have a GNU GRUB Menu and options to run Ubuntu from USB, Ubuntu from HD or Windows 7, so the Linux partitions are still there. But I want a menu to choose OS running at every startup.
