I just completed my dual boot with ubuntu 14.04 and windows 8.1.

There was no option to install ubuntu along side with windows so I used the something else option.

I had shrunk my C drive and got 215 gb of free space and used all that space for ubuntu. I could not get option to allocate swap so i didnt use swap.

After the completion of installation my computer boots only to Ubuntu. There is no option to choose windows.

Can any one help me to solve the problem.

I had my UEFI boot option off.

You will need to update your grub boot options. Open your shell from either the menu, or by pressing the global keyboard shortcut Ctrl+Alt+T, and enter the following command:

sudo update-grub

Upon reboot you should have a timer, and the full list of installed operating systems on your computer.

  • Updating the grub solved my problem. Thanks a lot man. Can you please tell me why we need to update the grub. Why it didnt detect the windows. – Bikram Jan 04 '16 at 01:52
  • on the newer versions I have noticed that the installer does not, for some reason, scan the installed OSes. So running this does the scan post install. – Siraj Jan 04 '16 at 19:47

I had the same problem back in 12.04, I solved it by installing the rEFInd Boot Manager. If you have a UEFI system (it most likely is if it came with Windows) this might work.

To install rEFInd:

$ sudo apt-add-repository ppa:rodsmith/refind
$ sudo apt-get update
$ sudo apt-get install refind

It will ask you if you want to install rEFInd to your ESP, say yes.

Reboot to save changes.

  • This looks good, and could work as a last resort but you should mention that rEFInd is a boot loader and will replace grub on the system, probably not a good option for beginners. – Mark Kirby Jan 03 '16 at 21:05
