光盘装ubuntu后win7启动项丢失

[woc2006]

win 7在g盘，ubuntu 在c盘。用了grubupdate无效。开机直接进ubuntu 。怎么修复？

把文件先复制到桌面，终端运行：

sudo bash ~/桌面/boot_info_script055.sh

把RESULTS.txt文件内容贴上来。
不是wubi装的我就试试。

好像没有好办法，重装吧，win7要装到主分区。
一个办法就是把win7装到c，删除最后一个分区，再重建一个分区（不要占用所有自由空间，留最后一块自由空间安装ubuntu）。
另一个办法就是删除最后一个分区，再重建二个分区，把最后一个分区转换成主分区，安装win7。这样不用重装ubuntu。
推荐第一个办法。

[woc2006]

C盘只有15GB，装不下win7，就算装下了，以后也有诸多麻烦。而且win7里还有些重要的东西复制不出来，必须要进系统处理一下才能重装。
这个扫描结果不是找到win7到引导文件了吗？难道不能手工编辑什么文件来启动win7？

[黄美姬]

我XP与WIN7双系统装在不同分区，进XP，XP就是C盘,进WIN7，win7就是C盘

windows要一个有active flag的主分区。现在你只有一个主分区。
想启动win7就要把c盘格式化，把win7光盘的/boot，bootmgr文件复制到c:，修复mbr，pbr，还要bcdedit添加引导项。

[woc2006]

那就先牺牲ubuntu ，c盘装个windows 系统，能自动找到以前的系统吗？

[onshoestring]

可以不安装系统，按7楼就能找回win7。
也可以装个xp，用autofixbcd找回win7。

[woc2006]

现在C盘已经装上win7了，接下来要怎样添加G盘那个win7？

[onshoestring]

1:bcdedit.exe在c:\windows\system32\
2:输入 bcdedit /store c:\boot\bcd /create /d "windows 7" -application osloader
(复制 返回的{xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx})
3:输入 bcdedit /store c:\boot\bcd -set {xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} device partition=g:
4:输入 bcdedit /store c:\boot\bcd -set {xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} path \windows\system32\winload.exe
5:输入 bcdedit /store c:\boot\bcd -set {xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} osdevice partition=g:
6:输入 bcdedit /store c:\boot\bcd -set {xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} systemroot \windows
7:输入 bcdedit /store c:\boot\bcd -displayorder {xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} /addlast

不知是否正确，有问题你google。

[woc2006]

现在已经都弄好了，双系统无误，不过有个小问题。上次装ubuntu重启之后就有声音了。这次没声音。安装时我跳过了下载更新，不知道会不会有影响？

[onshoestring]

没声音就是声卡驱动没装好，想办法装好声卡驱动。

标记下先。
