I'm triple booting now with win 7, ubuntu 9.04 and my main os sabayon 4.2
all of them were working sweet
but i noticed when grub was loading it was selecting sabayon too fast for me, 3 seconds i think, i wanted to change this, easy so after a quick google i edited the /boot/grub/menu.lst file and changed the timeout to 25 seconds
reboot to test, went into ubuntu and it failed to load ? it defiantly loaded before i went at grub,
i got this screen

i can boot up generic ubuntu, but what happened how can i fix
