I just installed Ubuntu 16.04 via burned CD on a new laptop (Lenovo Thinkpad) with Windows 7 installed. I chose to partition the hard drive the default way (~50/50 split) for a dual boot solution and generally accepted defaults during installation.
When I boot the machine, it goes straight to Windows. Booting from the CD indicates Ubuntu is indeed installed. I hold shift during boot but no Grub loader comes up. I've gone into the BIOS and checked for various fast boot options to disable but none really appeared (though I disabled a fast something or other for power from Intel, but that probably wasn't relevant). It loads both UEFI and Legacy and the default was to boot from Legacy first; I changed that to boot from UEFI first to no effect.
I've also tried to do the Grub2 solution:
sudo apt-add-repository ppa:yannubuntu boot-repair, etc. (I did it a few times.) I get an error:
The current session is in Legacy mode. Please reboot the computer, and use this software in an EFI session. This will enable this feature. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), after making sure your BIOS is set up to boot USB in EFI mode.
I tried following the instructions but didn't get anywhere. Is the default ISO from Ubuntu's website not 64-bit? Is there something else I should be looking at?
Thanks for any help you can provide!
