It sounds like your boot record has been changed to Windows and so you’re not having the Linux installation in the boot menu. Generally, Windows doesn’t support Linux booting and so, you have to use EasyBCD for the solution.

First of all, download and install EasyBCD. Download EasyBCD.

After installing it,

1. Go to “Add New Entries”.

2. From “Operating System” section, open “Linux/BSD”.

3. Choose “Type” to “GRUB 2”, select the partition of Linux installation from “Drive”.

4. Click “Add Entry”.


1. Restart your computer.

2. Select the Ubuntu boot choice and boot into Ubuntu.

3. Start a “Terminal” and run the following command:
sudo gedit /etc/default/grub

4. Change “GRUB_TIMEOUT=10” to “GRUB_TIMEOUT=0”.

5. Return to “Terminal”, run this command:
sudo update-grub

The task is complete and your Ubuntu installation is back again. This wiki will help you a lot.

I guess the reason why Linux Ubuntu didn’t show up during the boot is because of the upgrade you did to your Microsoft Windows operating system, from Windows 7 to Windows 8.1. When you started installing Windows 8.1, the installation wizard formatted your drive C which contains the boot configuration for your Windows 7 and Linux Ubuntu operating systems.

And when Windows 8.1 was successfully installed, it is obvious that Linux Ubuntu will not appear in the choices because no choices will be displayed because the boot configuration has been completely removed. In this case, Linux Ubuntu is disabled. Try the instructions in the previous post to possibly enable Linux Ubuntu and restore your dual-boot system.

But if it doesn’t work, you must reinstall Linux Ubuntu since Microsoft Windows 8.1 is already installed. There’s no need to reinstall Windows 8.1 if it is working properly. Making a dual-boot system with Microsoft Windows and Linux Ubuntu is easy but always remember that Microsoft Windows is always the foundation.

It is always the first operating system to install and Linux Ubuntu will only come next.
