筆電出現 Install Windows 無限循環死機畫面

朋友他是用華碩筆電，有天重開機進入win 7 後一直轉圈圈，等超久都沒反應後被迫重開，接著系統自動進入安全模式，說正在還原系統，接著一連串步驟後跳出下面一個視窗：
"Windows could not complete the installation. To install Windows on this computer, restart the installation."按ok，重開後一樣跳出該視窗，
有網友分享在虛擬機上遇過的狀況及解決方式，但試過影片中的2個方法還是沒有解決，

用原廠光碟片還原成 win8 pro 系統還是一樣出現該視窗，會卡在安全模式。

後來參考網路上另一個方法，關閉安全模式後重開，才能順利跑完系統安裝。

You may have an option to do a Repair on the POST screen before Windows tries to boot....
You may be able to quickly hit Ctrl+Alt+Del right at the end of POST to launch an automatic repair.
It might take three tries...

You need to get to the Command Prompt (.cmd)

 1) Boot from the Windows 8 DVD or any other available method....
      Steps 2,3,and 4 may not be in the sequence, depending on how you boot...
 2) Select Next
 3) Select Repair your computer
 4) Select Troubleshoot
 5) Select Advanced Options
 6) Select Command Prompt

This link gives instructions on what to do when you get a command prompt...

The instruction for the command...

bcdedit /deletevalue {GUID} safeboot where {GUID} is Windows 7 loader GUID.
{GUID}  is making reference to the "Identifier" listed under Windows Boot Loader which will display after entering bcdedit /v.

So in their example, the entry to the command prompt would be...
bcdedit /deletevalue {96378fc1-9402-11e0-990d-e3ec25d51f78} safeboot
