安装linux后，重新装windows，修复mbr引导

有时候，电脑为了短期干一个linux环境的项目，常常在电脑上装个linux环境，用几天后，又想卸载了重新装windows，可是现在装windows，为了省事，大家总是喜欢用ghost，结果发现ghost之后，系统无法引导，因为ghost后，虽然格式化磁盘，但并没有重写mbr引导分区

方法：

一、windows 光盘： 将Windows的安装盘放入计算机以后，重启计算机，进入Windows安装程序，随后，按R键进入恢复控制台，出现C:/windows之后，输入命令fixmbr即可。然后Y确定，即可。
二、mbrfix 1、下载mbrfix http://www.sysint.no/Download/tabid/162/Default.aspx （MBRFix ） 或者见附件
2、解压 将压缩包（mbrfix.zip）解压至系统根目录 C:\
3、修复mbr a.使用Windows PE光盘启动，进入系统 b.进入cmd命令窗口 c.然后进入mbrfix工具所在的目录

Drive numbering <num> starts on 0. Partition numbering <part> starts on 1.
Commands restorembr, fixmbr, generatesignature, writestate, clean, setactivepartition and fixbootsector will ask for confirmation unless /yes is included.
If the /byte option is given for the readsignature command, the signature is returned as a byte array instead of as a DWORD. Writesignature requires the new signature to be specified as 8 hex digits.
If /vista is used with the fixmbr command, a Windows Vista MBR is written instead of a Win2000/XP/2003 MBR. The Vista MBR should work with the other OS'es as well.
