如题：请问怎么修改？mac也准备删除，因为死活安装不成，下面是我的启动情况：
gzvb@gzvb-NC4400:~$ sudo update-grub
[sudo] password for ****:
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.35-24-generic
Found initrd image: /boot/initrd.img-2.6.35-24-generic

Found Mac OS X on /dev/sda9
done
gzvb@gzvb-NC4400:~$ ^C
gzvb@gzvb-NC4400:~$

到对应位置删除并编辑启动选项就好了。
或者用那虾米ubuntu-tweak 还是什么的删除启动选项。
