Hi!

I've installed windows xp pro and windows 2000 pro with a dual boot.I 've decided to format my hard drive but I still have the menu asking me if I want to run win xp or win 2000.

I know how to disable but why it happens?

thx

You did not format the system's primary boot partition. This happens if you have more than 1 hd, or more than 1 partition. You can check which is booting the system by finding ntldr , boot.ini, ntdetect.com or... open Disk Management and see what partition is defined as 'system'.

You will need to edit boot.ini (uncheck 'read-only') and delete the OS that is not used.

thank you

If you only have one main partition, this is simply a matter of WinXP setup not overwriting the boot sector. In Windows, open boot.ini (it's a hidden file on the c:\ drive) and remove the line referring to Windows 2000. Be aware that boot.ini may be read-only and you might have to change that attribute prior to editing.

Start|Run|msconfig is a quick way to get there-to the boot.ini that is
