使用Windows系統(tǒng)的用戶有時會遇到系統(tǒng)引導(dǎo)文件丟失，造成系統(tǒng)無法正常啟動。Windows系統(tǒng)引導(dǎo)文件丟失，即系統(tǒng)目錄下Boot目錄及Bootmgr丟失，一般的解決方案有如下兩種：
1. 進(jìn)WINPE系統(tǒng)進(jìn)行修復(fù)。
2. 利用bootbcd修復(fù)，bootbcd c:\Windows /s c:。
第二種方法可能會報錯：BFSVC: Failed to set element application device. Status = [c00000bb]，此時可以用如下的腳本進(jìn)行修復(fù)。
如將該腳本保存為Windowstest.bat，需要修復(fù)的盤為z盤，運行命令Windowstest.bat 即可。
