I love how everyone says boot usb or cd, but if your IT department was smart enough they would have disabled the boot other devices made the HDD the first and only boot option and then locked you out of the bios so you couldn't change it. If you really much do personal thing on the computer ask the company what you can and can not do with the laptop. If they say you can't do anything, buy your self another hard drive install your OS of choice and move on. Don't mess with their partitions and/or anything that's on the hard drive that's already there because most encryption software will log that kind of thing or prevent you from using the hard drive at all. I've got my work computer locked down, but it's video card is also really nice so I did this to my laptop. can't boot up CD's or USB sticks on it so another hard drive was my only options short of running a shell on top of my OS that it starts off with.
