I would like to know how to remove an operating system which is no longer on my computer even though the Windows Boot Manager thinks it is. I have Windows XP home on one hardrive and Windows 7 Ultimate on another hardrive. When I boot up my computer I get Older Version Of Windows and Windows 7 as booting choices. The default operating system is Windows 7 which boots fine when the 30 seconds is up. If I choose Older Version Of Windows I get two more choices: Windows XP Home and Windows XP Pro. I no longer have Windows XP Pro on my computer. I can boot into Windows XP Home OK, but I get an ntldr error if Windows XP Pro is selected. When I use EasyBCD under the ADD/REMOVE button I can only see two entries, Windows 7 and Older Version Of Windows. Is there a way to remove the Windows XP Pro entry on the second screen of the boot manager. I can boot to both operating systems fine, its just a nag that I have to go to that second boot screen when I want to use XP Home.
