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.
