I know that this question has been asked before, but none of the solutions have solved my problem.

Ubuntu boots and runs properly with the USB I used to install it plugged in to the computer, but when I shut down, remove the USB, and reboot, Windows Boot Manager appears. I am very confused why my computer wants anything to do with Windows because I chose to wipe my drive when installing Ubunbu.

I have tried using Boot-Repair, but Windows Boot Manager still launched when I restarted without the USB. Here is the log from Boot-Repair.

Try this:

Plug the USB and boot Ubuntu from HDD.

Unplug the USB.

Open a terminal,

Press Ctrl+Alt+T

Run it:

sudo -i
apt-get update
apt-get install --reinstall grub-common grub-pc-bin grub-pc grub2-common
grub-mkconfig -o /boot/grub/grub.cfg
grub-install  /dev/sda
grub-install --recheck /dev/sda
update-grub
reboot
