If you can't afford a whole other computer, use a bootable "live" Linux CD, like Knoppix - I got mine on a magazine cover-mount, but you can download it free from the link. Unless you install the appropriate drivers, it can't understand NTFS, so my hard drive isn't touched. It's very useful for repair work since you can get a machine up and running no matter what state its OS is in. I used mine recently to browse for information when I thought I had a virus.
