After removing the Ubuntu partitions from my earlier Ubuntu & Windows 8.1 dual boot from my Asus UX-305FA laptop I now still can find the Ubuntu options in the boot menu. I was told that to solve the problem I need to "remove /EFI/Ubuntu from my ESP and NVRAM from my UEFI". I made a Ubuntu LiveUSB but have now no idea as how to proceed.
All help appreeciated.
