Same situation as Niko. My laptop at the time of install, had only 256mb of memory it was very slow to install, probably took about an hour to install. No worries used to doing that with windows
But definately skip out on options like choosing time etc... It will make the system seem to hang but its actually taking a long time to go through the process.
Unfortunately there really needs to be an alternate non gui install of mint, perhaps in the future.
