Why Ubuntu appears in boot options after I uninstall it?

Question

I'm new in this forum; I've got an Asus s56 laptop with Windows 8 installed and UEFI bios; I have to use Ubuntu to work, so i installed it on an external hard drive; Few days ago i had to uninstall Ubuntu, and when i entered the boot menu i realised that maybe i installed the boot loader in windows hard disk, because in the boot list there is the ubuntu option;if I try to boot from it ,the grub doesn't find the partition (and this is what I expect, because Ubuntu was on an external disk); somebody on this forum suggested to delete the directory EFI/ubuntu , but i don't find it in my EFI partition; so, the question is : how can i delete the unused boot option without making mistakes?

Thanks and sorry for the errors, I'm from Italy

may be msconfig can help you. you can reduce seconds of waiting (from 30 to 3)

or you can use windows disk and recover boot loader. in command prompt BootRec.exe /FixBoot (if i am not wrong)

you must do it in recovery mode, from boot disk.

I'm not positive, but I think that the bootrec.exe tool is useful only on BIOS-based computers. User210333's system is EFI-based, so the procedure is different. – Rod Smith Nov 02 '13 at 02:12
Thanks for your answer. I tried the command BootRec.exe /FixBoot in the command prompt of Windows 8, but it didn't work – user210333 Nov 02 '13 at 09:59
