I have a HP Probook 440 G2 and it is installed with Windows 8.1 in UEFI Mode. I used Rufus-2.1 software to boot Ubuntu in the USB in GPT Prtition Scheme and tried to install Ubuntu. The OS got installed and asked to restart the computer but after restart there is no option to boot into ubuntu in the pc booted directly to Windows. So i went to advanced startup and in UEFI Firmware settings tried to boot with USB, but is showed no OS found. But the OS is surely installed since the size of the hard disk in windows got less or in disk management there are more partitions which are not from windows, so what should i do.
But this does not happen when i boot in legacy mode. Meaning, i installed the windows in legacy mode and then ubuntu in legacy mode and it worked with no problems. But then when formated and booted windows in UEFI and the tried to install Ubuntu the above problem occured.
I still am i UEFI mode and cannot use Ubuntu.
Please help me.....
