Setting boot order with efibootmgr
I am dual-booting Fedora and Windows on a UEFI system. In efibootmgr I can see entries for Fedora and Windows, but I can also see other entries such as DVD, USB, internal hard disk.
When setting the boot order, do I need to include these other entries (DVD, USB) in addition to the entries for the two installed operating systems? If I do not specifically include them when setting them using efibootmgr -o, will they be removed from the boot order?
Do I need to delete the existing boot order before setting a new one? What happens if I delete the existing boot order without setting a new one?
