I dual booted my windows 10 pc with ubuntu (HP i5 7th gen) using usb flash drive method. It asked me to restart but when I restart the computer (with usb connected) there are no options for windows 10 or ubuntu.. It is like this, GNU GRUB version 2.02 Try Ubuntu without installing Install Ubuntu OEM install (for manufacturers) Check disc for defects
Thats all. When I tried installing it again, it says Ubuntu 18.04 is already installed.. but I can't find it where. When usb is not connected and I start the computer.. windows 10 automatically opens. Please help me with this... P.S: I turned off secure boot in UEFI settings
