win7通过硬盘安装Ubuntu 16.04 LTS镜像的经历
周末在家闲着无事，想装一个ubuntu系统玩一玩，最近也了解到ubuntu最新版Ubuntu 16.04 LTS发布了，也好奇Ubuntu 16.04 LTS版本真如网上说的那样多的特性么，试过后知道，确实界面好看些了。讲讲我这次在家用本上安装Ubuntu的经历，首先我是看了
《Windows 7下硬盘安装Ubuntu 14.10图文教程 》教程安装的Ubuntu 14.10版本，下载一个《
EasyBCD》的工具，照着教程做，系统就安装好了，安装完之后，连接上拨号网络(怎么设置连接拨号网络，请看后面说明)，发现很多软件下载不了，网上一查，说是Ubuntu 14.10的官方不再支持源的缘故，这才知道白安装了，然后又回到win7系统，下载了一个
Ubuntu 16.04 LTS版本32Bit的官方镜像，接着我在磁盘管理里面，把之前Ubuntu 14.10占用的分区，直接"删除卷"了合并到一个分区，重启系统，发现傻眼了，ubuntu系统分区被我删除卷了，出现了grub rescue提示信息，win7系统也进不去了，网上搜了一堆，如果通过ls命令(ls (HD0,msdosx))仍旧不行的话，只能通过启动盘来引导进入win7系统，于是下载了《
U盘启动大师》工具，制作了一个U盘启动，重启系统，接着按F12，选择U盘选项，进入U盘引导主界面，选择<重启计算机>选项，进入了眼熟的win7引导界面了，按下拉箭头，选择EasyBCD的引导项，重新安装ubuntu(因为我之前已经把Ubuntu 16.04 LTS的iso、initrd.lz和vmlinuz放到了C盘根目录下，此时安装的就是Ubuntu 16.04 LTS的镜像;如果没有放置，进入win7系统先把它们放置到C盘根目录下)，至此Ubuntu 16.04 LTS才算安装完成。
win7通过硬盘安装Ubuntu 16.04 LTS镜像的经验：
1.win7下卸载ubuntu时，千万不能通过磁盘管理直接格式化Ubuntu的分区或删除卷，否则会导致win7系统也就不去了。因此卸载ubuntu时，需用通过一个工具《
MBRfix》来修复MBR，去掉ubuntu引导，然后再去格式化ubuntu的分区，就完成卸载了。
2.如果不小心通过磁盘管理直接格式化Ubuntu的分区或删除卷了，需要通过启动盘引导进入win7系统，可以制作一个U盘引导启动
3.ubuntu拨号上网的设置方法：
直接在界面的网络管理器中-->"编辑链接"-->“添加”-->“DLS”；在DSL页，填好用户名和密码，服务可以不填；在以太网设置页中的MAC页面“设备MAC地址”选择需要的地址，通常就一个网卡；在PPP设置页中，将回声关闭（频繁掉线配置各种无效，但是只要将回声关闭就可以），然后保存后连接即可。
PS:MBRfix工具的使用方法：
D:\用户目录\下载\Compressed\mbrfix>
MbrFix.exe /drive 0 fixmbr
You are about to Fix MBR,
are you sure (Y/N)? y
D:\用户目录\下载\Compressed\mbrfix>
重启机器，即可发现ubuntu开机选项已经被去掉啦。
