When I first got my netbook I initially wiped it and used the MBR partition scheme and installed 7, 10.5.x, and UNR. Then SL came out and I decided it's easier to manage 1 OS and since SL only worked with GPT (MBR method never worked for me) I just installed SL on a single 160GB GPT formatted drive. Now since the ChromiumOS release is soon, new Ubuntu, etc. I've been wanting to partition my existing SL GPT and add possibly a /Data, /Windows, /Extended (Linux/Swap) like my desktop is setup.
How possible is this with my GPT and already installed SL setup? I only have a 4GB USB but I used a friends 8GB for SL before.
PS I know I can run these OS's off of USB drives but since I have a 160GB, why not sacrifice some space for speed?
