Enable Safe Mode booting
When a system is booted in the safe mode, it allows only certain Windows processes to run in the Task Manager. Thus, several viruses cannot run in this mode. Hence there are certain viruses that disable the booting of safe mode in a computer. However, this mode can be enabled again by following the mentioned method below:
- Go to Start --> Run and type msconfig
- Now select the BOOT.INI tab and check the /SAFEBOOT option.
- Now Reboot your system and you can find the option working.
