安装fedora14后没有ubuntu10.10的启动选项

[ykmingk]

看着fedora很漂亮，想安装一下试试，可是用U盘安装fedora14之后重启，fedora和xp都可以正常进入，但是在启动菜单里没有了ubuntu，请问需要怎么解决啊？谢谢

要看fedora14是grub1还是grub2。
把menu.lst menu.conf类似的菜单贴上来。

我查的好像是grub1
这是fedora14中的menu.lst 位于/usr/share/doc/grub-0.97

这是内容：
#
# Sample boot menu configuration file
#

# Boot automatically after 30 secs.
timeout 30

# By default, boot the first entry.
default 0

# Fallback to the second entry.
fallback 1

试试加入：
ubuntu /boot没有单独分区

title Ubuntu
find --set-root /boot/grub/core.img
kernel /boot/grub/core.img
boot

ubuntu /boot单独分区

title Ubuntu
find --set-root /grub/core.img
kernel /grub/core.img
boot

[ykmingk]

额我不太明白，是在menu.lst后面直接加上
title Ubuntu
find --set-root /boot/grub/core.img
kernel /boot/grub/core.img
boot
吗？

[onshoestring]

# For booting Windows NT or Windows95
title Windows NT / Windows 95 boot menu
rootnoverify (hd0,0)
makeactive
chainloader +1
# For loading DOS if Windows NT is installed
# chainload /bootsect.dos
加这里
# For installing GRUB into the hard disk

setup (hd0)

提示是只读文件，没有权限修改，
我复制了一份然后修改，在终端里用sudo mv移动覆盖掉，还是不行
我在U盘系统里直接复制还是权限不够，在终端里提示liveuser is not in the sudoers file. This incident will be reported.
我想切换用户用root登录，可是输入密码后提示说验证障碍
这个权限怎么弄啊，我快疯了

/usr/share/doc/grub-0.97你这个目录不对，是说明文档目录。不是系统菜单目录。

开机进grub菜单 按e 编辑菜单
find --set-root /boot/grub/core.img
kernel /boot/grub/core.img
boot
就启动到ubuntu了。
