I'd suggest running Live USB instead from CD, using Persistence. if you're using Windows here's a fine tool to create the USB stick, and you have to set the USB drive ahead of other drives in your computer's BIOS for booting:http://www.pendrivelinux.com/universal- ... -as-1-2-3/
I'd suggest a 4GB USB drive, with 1.5 GB set for the Mint, and the rest allocated to "Persistence."
The advantage of Persistent Live USB is it behaves pretty much like a regular installation, saving your settings and even your additions and deletions of software - you can really use
Mint in a way you can't from CD. In my experience, over a year or so with many versions of Linux, the Live USB always seems to wonky after a few weeks of regular use, demanding passwords or failing to find the hard drive, so I don't consider it a reliable substitute for a real installation, but it is far better than Live CD.
New to Linux. Installed Lubuntu 10.10 on Acer netbook, and experimenting with Mint 13 and other distros on Dell laptop with peripherals (Persistent Live USB).
