So a few months back I bought the MBP Retina as I was impressed with the ones at work. Our work folks run 2 Parallels on the. One windows 7 and one windows 8. This is what I hoped to do. I bought and installed parallels and loaded Win 7 on there. Unfortunately I no longer have the disc. I bought a Win 8 Product key, but didn't do anything with it as I was still exploring. Fas forward, I cant update or do anything because the startup disc is full msg keeps coming up and it looks like Parallels is taking 60 of my 120 GB. The work ones have the 2 VM at 30 combined. What Could I be doing wrong? Thanks!!
