Multiple operating system problems.

[peakaboo]

I cut the long story short.

Basically i have a 32 -bit com which basically when boots up i get a choice to either boot -

-ubuntu
-Windows xp
-windows Xp 64

i do not want to have the windows Xp 64 choice to boot, i found on the internet some help, but not enough, here is what i need to edit.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS.0
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS.0="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP Professional x64 Edition" /noexecute=optin /fastdetect

so do i just change the above to this below ? or is that wrong? Any help appreciated.
