1. Boot Lock

This one allows you to use your tesla dashcam usb size as a booting device to your Windows Computer. If someone tries to start the computer without your USB Drive, it will display boot errors.

Before begin, you will be playing around with the BIOS and boot files of your computer may result in you not being able to boot into your Windows partition; so continue at your own risk!

Things you need: A 64MB or larger sized USB Stick, Windows Recovery Disk (just in case).

Unhide hidden and protected files : Go to Tools > Options > View > check Show hidden files and un-check Hide protected system files.

  • From the drive where Windows is installed (normally C:\), copy the files boot.ini, ntdlr and NTDETECT.COM to your USB Stick.
  • Now, we need to go into your BIOS, so restart the computer and keep pressing [F8] or [DEL] whichever is required to enter the BIOS of the computer, as soon as the computer starts.
  • Once in the BIOS, enable USB Drive as the first boot device. You might have to enable USB Legacy  Support on older BIOSes.
  • Restart your computer, if all goes well, you should be able to log into Windows. If not, then unplug the USB Stick, return to the BIOS and change the First Boot device to your hard disk drive and repeat the steps above.
  • Once you are logged into Windows, go to your Windows drive and rename boot.ini to boot.bak.
  • To check if you have setup everything correctly, eject your USB stick and reboot the computer. You should get error messages on the screen such as Invalid Boot.ini” or “Windows could not start”.

VOILA!

2. Use Predator Tool to control the Access to your Computer

Predator locks your system when you are not around, even if your Windows session is still opened. Use a USB flash drive as an access control device.

Download and install Predator, pair a USB drive with it. With the USB drive plugged in, you can continue to use to computer, but as soon as it is removed, the screen darkens, the PC locks, and keyboard/mouse input is disabled. Plug it back in, and normal usage is restored.

  • First download Predator from here. And install it.
  • After installation launch it from desktop shortcut icon.
  • A window will open to set up password and request for USB flash drive insertion, click OK.
  • In the Preference window, configure all settings and create a Key.
  • Once you’ve done the configuration, Hit OK to save the Changes, and restart Predator
  • You are ready to go!
