I have successfully installed Ubuntu 14.04 on a Lenovo machine that runs Windows 10 After the installation is finished, the machine restarts and automatically boots into Windows every time I start the machine. I have checked the boot list but Ubuntu is not there although I got successful installation message. Also the directory that I selected for Ubuntu to be installed in disappeared from Windows directories. My machine runs in BIOS Legacy mode and the System Information tells me that Secure Boot State is unsupported. I tried the startup repair but with no luck. And when I change mode from legacy to UEFI I get no boot loaded other than the IPv4 and IPv6 ones which fail to load anything. Three questions:
How to make the directory where I installed Ubuntu visible in Windows?
How can I get a boot window to select an OS to boot the machine into every time I open the machine?
And before all, how from Windows, can I verify that Ubuntu was in fact installed properly?
