well i have located the boot.ini file, i removed the /noexecute=optin and replaced it with /NoExecute=AlwaysOff , when i try to save it refuse to save and tell me can not save..... so how??

the file looks like this;

[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" /noexecute=optin /fastdetect

i am removing only the red color words
