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!

  • File name of the iso I downloaded is ubuntu-16.04.1-desktop-amd64. Seems to suggest a 64 bit file. Full error message is: "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." – Michael Nov 3 '16 at 3:04

    The problem is the UEFI+Legacy mix up and the fact that you installed Windows 7 (Legacy) and Ubuntu (UEFI) in different modes. – user589808 Nov 3 '16 at 3:15
  • @Michael "amd64" indicates 64-bit (AMD) architecture. "i386" indicates 32-bit (Intel) architecture. – wjandrea Nov 3 '16 at 3:21
  • Could you please run Boot-Info and edit your question to include a link to its resulting info log? Thanks. – David Foerster Nov 3 '16 at 10:35
  • Please run the Boot Info Script. This will generate a file called RESULTS.txt. Post that file to a pastebin site and post the URL to your document here. This will give us more details about your configuration, which is required to base an answer on more than guesswork. – Rod Smith Nov 3 '16 at 18:24
