kevyb, welcome to the forum! One additional consideration that you may need to look at, is your amount of installed RAM (2GB, per your specs). 2GB is the minimum recommendation to run Win 7 64 bit. If you run ANY VM, you'll need some extra RAM to lend to the VM. Usually a minimum of 256MB for a Linux OS, 512MB for a 32 bit Windows OS, except Win 7 or Vista, you'll need 1GB to spare.
Lookup your computer's specs and see how much RAM it can hold. You're going to need at least 3GB, preferably 4GB RAM for acceptable VM performance. I speak this from experience, as I've been running VM's for over a year, both inside of Windows 7 & Linux Mint.
Best of Luck,
Cat
