I have a really old Dell desktop that has/had Windows XP on it. I rarely used it due to its slowness. I recently started my Masters in Cybersecurity and and we use Linux terminal quite a bit. So, I wanted to re purpose this machine in order to get more comfortable with Linux. Yesterday I moved all important files to an external HD and completely replaced Windows with Ubuntu 14.0.4. However, even after a fresh install it is still very slow booting and opening applications. Is there a more basic Linux version I should go w/ that would be more efficient? I don't need all the extra software that Ubuntu came with. Currently the desktop has these specs:
2 GB RAM
80 GB HD
Intel Pentium 4 HT 3.00 Ghz
I want something that is fairly basic and quick that I can utilize efficiently in my hacking techniques classes. Any suggestions or recommendations would be greatly appreciated.
