This situation is the PC was upgraded from Windows 7 to Windows 10.

Then Ubuntu was installed. When I installed it the prompt asked if I wanted to install it along side Windows 7 even though the upgrade to 10 was complete.

I proceeded with the installation and it appeared to complete without errors.

However, it still boots directly to Windows 10 without a dual boot option.

At this point I am not sure how to boot to Ubuntu to fix grub. I have read some solutions for grub but I need to get into Ubuntu first.

The option to "try Ubuntu" works but that is only running off the thumb-drive.

Any suggestions? Thank you very much.

  1. log into windows partition
  2. install UNetbootin
  3. download Grub2 iso,
  4. use UNetbootin, to create a bootable USB with it.

then restart your system, and boot using the bootable USB.

that will allows you to fix your GRUB.
