deleting and os

[James Takac]

Hi Guys

Have a friend that I have finally got used to Ubuntu. He's sick and tired of 
having to fix windows and this time it would need a complete reinstall to 
fix. So what he wants is to get rid of windows entirely (sys is currently set 
to dual boot) but I don't think a complete reinstall of Ubuntu is necessary 
as he thinks it to be. Can I in effect just redo the current windows partion 
and format it ext3 or so and just modify the entries in /boot/grub/menu.lst. 
Or will I need the live cd to boot from and the re setup grub from there?
