Does anyone know if it would be possible to install windows 7 on an SD card so that I could run 7 from the card and not use the hard drive? I don't want to have to partition my HDD to conserve space. I could get a 64GB SD card for not very much. Has anyone tried this? I was also thinking that it might be possible to instal lion onto it so if my HDD ever died, the computer could still be booted up and used, although without the files on my HDD.
