Security mode is a system mode that we often use in system problem processing. It is a repair system mode that comes with windows system, but when our system is lost due to files. Can't use F8 to enter safe mode, then what should I do? Let Xiaobian come to share with you how the win7 system can't use F8 to enter safe mode.
Step 1: Press the Win key + R key combination key on the keyboard to open the ghost win7 & ldquo; Run & rdquo; window, then enter the regedit command and press Enter to open the win7 system registry manager.
Step 2: Follow the path HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\SafeBoot to open the project that the win7 system registry manager needs to edit.
Step 3: In the win7 system registry manager, we look for a subdirectory named "ldquo;minimal" in the SafeBoot directory. Just fix all the secondary directories in this subdirectory, the security mode of win7 system. It is possible to resume F8 entry.
Step 4: In this subdirectory named “minimal”, we found the data related to the disk drive related data project, the file system related data project, the SCSI support related project and the Base project. The security mode of the win7 system can restore the F8 entry.
