Remove unwanted entry in UEFI BIOS boot menu

If your original OS is installed in UEFI mode, the installation of some other OS (e.g Ubuntu) in UEFI mode later on introduces some artifacts to the EFI partition the hard drive, and due to them, in the UEFI BIOS boot menu you see the respective boot menu entry. To remove the entry completely, you need to remove the artifacts to the EFI partition, and then move the respective boot entry. Delete EFI/distro of the EFI partition Linux Locate your EFI partition with sudo fdisk -l and find out the partition with EFI Partition under the Type column. Suppose the EFI partition is /dev/sda2 , do the following to mount it on an empty folder. mkdir /mnt/efipart mount /dev/sda2 /mnt/efipart Next find the directory corresponding to the OS that you have installed. It is mostly under EFI/ distro_name Remove that directory and its contents by sudo rm -r EFI/distro_name . Windows Start cmd.exe as administrator. Run diskpart in it.
