To repair Windows Advance Option (F8)
The reason for corrupt of Windows Advance Option - Safe mode & other are not work (system restart or error of BSOD) is Virus. Some Virus remove the Windows Advance Option Menu Setting.
To resolve the issue:
The registry keys to boot into Safe Mode are under the SafeBoot key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot
You can boot into Safe Mode without or with networking, there is a subkey for each mode: Minimal (no networking) and Network (with networking).
Each device, driver or service that has to be started has a subkey under the Minimal or Network key.
If you want to disable a device, driver or service in Safe Mode, just delete the corresponding subkey (make a backup first).
I tested this with key {4D36E965-E325-11CE-BFC1-08002BE10318} (resulted in a disabled CD-ROM drive) and PlugPlay (resulted in a disabled Plug and Play service).
I compared several SafeBoot registry keys for Windows XP SP2 on different hardware platforms, and they were all identical. However, there were some small differences when comparing different operatings systems (Windows XP SP1, SP2 and Windows 2003 SP1). Remember that Safe Mode was introduced with Windows 2000.
These are minor differences, just listing devices, drivers or services that are only present on one version of Windows. For example, I found Volume shadow copy on a Windows 2003 and not on Windows XP. And Windows 2003 also had less network services than Windows XP, this is probably a result of the default hardening of Windows 2003: more services and applications are disabled by default on Windows 2003 than on Windows XP.
To repair you PC for Working of Windows Advance Option Menu insert or check the safe mode registry setting is there if not insert it. If you want to insert the Safe Mode default registry setting than download the attachment & Import it.
