Removing Ubuntu boot option?

Question

I had installed Ubuntu inside Windows, then decided I didn't need it, so I tried to uninstall. It needed the disc, which I didn't have at the time, and I really needed the space, so I just deleted the installation folder. The option to boot into Ubuntu still shows up though, is there any way to get rid of it?

Answer 1

If you are on xp or lower go to boot.ini and delete the entry for ubuntu. If you are on vista or higher

run cmd as admin
type in bcdedit
go to the boot loader section
locate the os entry that you need to remove
copy the entry against identifier
type in Bcdedit /delete {boot loader identifier}

braces are required

Answer 2

The boot menu is not part of your bios (as you had tagged your question), but displayed by the boot manager (sometimes "boot loader").

In Windows XP and earlier, the boot menu items are stored in \boot.ini of your system volume; you can edit the text file directly with Notepad, or run bootcfg /delete /id entryid from Command Prompt. (To list entry IDs, run bootcfg.)

In Windows Vista and later, the boot menu items are stored in BCD and editable using bcdedit from elevated Command Prompt, or such tools as EasyBCD.
