安装过linux系统的朋友，有过这样的经历，安装Ｇrub的时候，把硬盘的MBR修改了，但是删除ＬＩＮＵＸ的时候，却连原来的ＷＩＮＤＯＷＳ系统也启动不了，怎么办？
写入MBR的方法，有两种比较简单
第1种方法：就是将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，进入恢复控制台，输入命令fixmbr即可。
第2种方法是为没有Windows安装盘的朋友准备的，就是使用MBRFix工具进行修复。
MBRFix工具修复MBR很方便，先进入cmd命令窗口，然后进入mbrfix工具所在的目录（用cd命令），然后输入命令 MbrFix /drive 0 fixmbr ，再确认一下即可。重启以后你会发现，没有了Linux，直接可以进入Windows了。
附一：MbrFix命令
Commands:
MbrFix /drive <num> driveinfo Display drive information
MbrFix /drive <num> listpartitions Display partition information
MbrFix /drive <num> savembr <file> Save MBR and partitions to file
MbrFix /drive <num> restorembr <file> Restore MBR and partitions from file
MbrFix /drive <num> fixmbr Update MBR code to W2K/XP/2003
MbrFix /drive <num> clean Delete partitions in MBR
MbrFix /drive <num> readsignature {/byte} Read disk signature from MBR
MbrFix /drive <num> generatesignature Generate disk signature in MBR
MbrFix /drive <num> readstate Read state from byte 0x1b0 in MBR
MbrFix /drive <num> writestate <state> Write state to byte 0x1b0 in MBR
Drive numbering <num> starts on 0.
Commands restorembr, fixmbr, generatesignature, writestate and clean 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.
