I've installed Windows 8.1 and Ubuntu 14.04 in my Sony Vaio SVS13A1S9ES and I haven't had any problems during the installation. However, when I turn on the computer, I boot with Windows 8.1 and I'm never asked if I want to boot with Ubuntu.



I've been looking for solutions: I've tried to disable the Secure Boot of Windows but this option doesn't appear in BIOS menu. I neither can boot manually pressing F11 because when I do it the following message appears: "operative system not found".



The only way I've found to boot with Ubuntu is by inserting the Super Grub2 Disk CD. The problem is that I usually have to change between Ubuntu and Windows so I wouldn't like to carry a CD everywhere to do it.



Is there any solution for dual-booting without an external device?



Thank you in advance

I understand that the Windows 8.1 secure boot feature complicates life. I had a similar problem in that I only got Ubuntu, not Windows. However, I believe the solution I found suggested on several sites would apply in either case, assuming the approach in the previous post did not.



When you are in Ubuntu (I gather you can get in wi,th some difficulty) install "boot-repair" as follows: Openl Terminal (ctrl+alt+t) and enter the three following commands



sudo add-apt-repository ppa:yannubuntu/boot-repair

sudo apt-get update

sudo apt-get install boot-repair


Open boot repair from your dash and select “Recommended repair”. From there on I merely did as I was told. ON restart, the Grub did its job.
