Today I updated my system after a while away (moving). It wasn't able to do all the updates for some reason (can't remember the error message). so, i tried to restar. Now when I turn the system on it boots to a white screen. I have tried to fix it by booting into recovery mode in order to try running the remaining updates, but to no avail. It doesn't ever get me to a prompt when I choose the network option.
Please help quickly.
