急……求救，装Ubuntu后无法进入win7。。。

[zby0826]

本人新买的电脑，预装WIN7，装Ubuntu的时候在准备开始安装的高级选项里，选了安装引导程序在WIN7所在的dev/sda2……
结果出现问题，在GRUB界面下选择win7，按了之后光标闪了几秒再次回到GRUB界面，无法进入WIN7系统。
向高手求救。。。

[onshoestring]

/etc/grub.d/40_custom加入如下内容：

menuentry "Grub for Dos" {
search --set -f /grub.exe
linux /grub.exe
}

代码： 全选

sudo update-grub

下载grub4dos， http://nufans.net/grub4dos/current_release/grub4dos-0.4.4-2009-10-16.zip，把grub4dos文件grub.exe复制一份到c:\

c:\建立一menu.lst文件，内容如下。

default 0
timeout 0
title Windows
chainloader /bootmgr
boot

能不能再通俗一点 啊 ,小 弟刚玩UBUNTU 什么都不会.......

[onshoestring]

要更通俗就把我难住了。
你有win7安装光盘或pe么？

[zby0826]

预装是64位的系统，有的系统盘却是32位的，试了没用……
呃，怎么在/etc/grub.d/40_custom里加入内容啊？grub.cfg说不让修改……下面那一行代码又是什么意思啊？
还请大虾帮忙啊……

[onshoestring]

代码： 全选

sudo gedit /etc/grub.d/40_custom

加到文件最后空白处

[zby0826]

试了，还是不行啊……
grub里按WINDOWS 7还是一个情况，多了一行“grub for dos”，进去之后闪几下按“windows” 出现：
Booting windows
chainloder /bootmgr
error 15 :file not find
。。。。。。
怎么办呢？

[onshoestring]

在浏览器里 ctrl-c 是复制，在终端里 ctrl-shift-v 是粘帖
终端运行：

代码： 全选

 cd ~/桌面 && wget 'http://nchc.dl.sourceforge.net/project/bootinfoscript/bootinfoscript/0.55/boot_info_script055.sh' && sudo bash boot_info_script055.sh

把RESULTS.txt文件内容贴上来。
