While installing ubuntu 20.04 LTS desktop with a bootable usb, I used easyBCD (free version) on windows to add/manage the boot menu. I had chosen the root partition of linux ( / ) to write the boot while installation. I now have three boot options with a windows and two linux (a duplicate which I add inadvertently in easyBCD). I tried removing the duplicate linux boot menu with easyBCD and Grub Customizer without success. The duplicate linux boot menu is bothering me and I want it gone.
Any suggestions and help is highly appreciated. Thanks in anticipation!
