(another slow reply)
I have two 120gb External hardrives.
also, I dont need to backup the WHOLE computer, just some important things (though installing everything will be annoying)
also, I should have enough space on my desktop to backup important things (IE pictures)
but for now I'll try to find some guides on google.
Edit:
I've been looking at this but am leery of trying it since it asks me to delete several important files.
