Multi boot prompt windows XP

[Smurfjet]

After some trouble with an XP installation, I re-installed a second one on the same drive and deleted the one giving the trouble. Works fine except on boot, I get a menu to select which OS I want to boot with. I'm guessing MBR thinks there are 2 OS still installed? Would like to fix.

Thanks for the help.

Edited to add boot.ini contents

Here is the content of the boot.ini file

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /noexecute=optin
