Dism /Online /Cleanup-Image /ScanHealth
掃描全部系統文件和系統映像文件是否與官方版一致（無論你是否備份或製作過系統映像）
Dism /Online /Cleanup-Image /CheckHealth
檢查文件的損壞程度
DISM /Online /Cleanup-image /RestoreHealth
一般性損壞可以修復
Dism /online /Get-CurrentEdition
檢查映像版本
Dism /online /Get-TargetEditions
檢查系統是否可升級
咱們首先需要將映像（.iSO）「裝載」在系統中，然後
Dism /Apply-Image /ImageFile:X:\sources\install.wim /Index:1 /ApplyDir:C:\
其中，X代表映像掛載後的盤符
mdadm –zero-superblock /dev/sda1 /dev/sdb1

dd restore image
gunzip -c centos-disk.gz | dd of=/dev/sdb
conv=noerror #告訴 dd 繼續操作，忽略所有讀取錯誤。
sync #如果有任何讀取錯誤，則添加帶有零的輸入塊，因此數據偏移量保持同步。

映像恢復到任何 sdb： 上述命令將保留分區模式
dd if=/tmp/mbrsda.bak of=/dev/sdb bs=446 count=1
分割區備份
sfdisk -d /dev/sda > /tmp/sda.bak
分割區恢復
# sfdisk /dev/sda
only delete MBR
dd if=/dev/zero of=/dev/sda bs=446 count=1
delete all partition and MBR
