Windows 7藍屏自動重啓，無法修復，做系統還原時錯誤代碼：0x8000ffff，藍屏時錯誤代碼：0x0000007B，此時如果用PE盤啓動，硬盤中所有文件都在而且可以正確讀寫。
原因是BIOS中，sata類型在AHCI或raid或ide之間有修改。
處理辦法：
1.Boot OS DVD
2.Choose the Language Selection.
3.Choose Repair.
4.On the recovery tools choose the Command Line Console
5.Type:regedit
7.Highlight HKEY_LOCAL_MACHINE
8.File > Load Hive
9.Select \Windows\System32\config\system (Backup this first, it's advised)
10.Regedit will ask for a Key name: Name it something like "temp"
11.Located HKEY_LOCAL_MACHINE/temp/Select/Current
12.Searched for every key containing the value “SCSI Miniport” where the "Start" value was a "3" and changed the "Start" value to a "0". (F3 to search next result).
13.Highlight "temp"
14.File > Unload Hive
15.Restart
16.Enter into your OS
其中的三個主要的鍵值中的Start要改成0，不要遺漏：
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\pciide
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStorV
