What mode did you install Ubuntu in? If Windows 8 is installed in EFI mode then Ubuntu has to be installed in EFI mode.


Having a PC with EFI firmware does not mean that you need to install Ubuntu in EFI mode. What is important is below:


[*=left]if the other systems (Windows Vista/7/8, GNU/Linux...) of your computer are installed in EFI mode, then you must install Ubuntu in EFI mode too.
[*=left]if the other systems (Windows, GNU/Linux...) of your computer are installed in Legacy (not-EFI) mode, then you must install Ubuntu in Legacy mode too. Eg if your computer is old (<2010), is 32bits, or was sold with a pre-installed Windows XP.
[*=left]if Ubuntu is the only operating system on your computer, then it does not matter, you can install Ubuntu in EFI mode or not.
