我在win7下硬盘安装来ubuntu10.10，更新完后用ubuntu tweak清理了多余内核，但使用update-grub启动项仍然有两个内核，如下：
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.35-23-generic
Found initrd image: /boot/initrd.img-2.6.35-23-generic
Found linux image: /boot/vmlinuz-2.6.32-24-generic
Found initrd image: /boot/initrd.img-2.6.32-24-generic
Found memtest86+ image: /boot/memtest86+.bin
Found Windows 7 (loader) on /dev/sda1
我用命令 dpkg --get-selections|grep linux查看内核为
libselinux1 install
linux-firmware install
linux-generic install
linux-headers-2.6.35-23 install
linux-headers-2.6.35-23-generic install
linux-headers-generic install
linux-image-2.6.35-23-generic install
linux-image-generic install
linux-libc-dev install
linux-sound-base install
pptp-linux install
syslinux install
syslinux-common install
util-linux install
请问这是怎么回事，如何解决，谢谢。

只要开机的grub选项里没有显示两个内核就可以了
