I just fresh install Zorin OS core then rebooted after installation then the boot menu pops up waiting for me to select an OS the selections are
Zorin OS
Advance ...
Windows bootloader
System setup
Im not using a dual boot however there is a Windows 10 install in my other hard drive.
I dont want that to appear I want it straight boot up to Zorin OS
Ive tried every solution on every thread that I could find
even configuring the /etc/default/grub file then sudo update-grub.
removing those other selection using grub customiser it did not work
I hope I can find my answer here
