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.
