I am currently in a far, far place away from home where I have my beautiful beast of a computer that hosts so many games, softwares, songs and... confidential stuff (some related to my company) on different drives. I also have remote access to that computer.
The problem is in the form of my teenage cousin who is home for the holidays in two days; I do not want him to access anything. He has a tendency to think of himself as a "guru" and "fix up" all the computers he ever comes in contact with - by reinstalling the OS to "speed things up" and installing lots of unwanted games etc.
I have two drives - C: and D: - 250GB each. I could easily access the machine remotely and set a password on my only account, but knowing him, he will format my C: drive and install Ubuntu, still having access to the D: drive (NO! I am NOT making this up. he has done this before).
How can I lock my drives so he won't be able to format, fdisk, install another OS or do anything at all?
I'm running Windows 7 Ultimate 64-bit.
