1st days of learning Linux

I really don't know what to do on the first day of Linux's 1st day, because all kinds of work are carried out in windows, and I don't want to restart the machine, so I don't want to install dual systems, I used the vmwarevm, and installed Ubuntu12.04 on the virtual machine, wow, virtual machines are really slow.

I really don't know what to do on the first day of Linux's 1st day, because all kinds of work are carried out in windows, and I don't want to restart the machine, so I don't want to install dual systems, I used the vmwarevm, and installed Ubuntu12.04 on the VM, wow, virtual machines are really slow. Baidu has a variety of slow reasons. this is the case in the original virtual machine. someone suggested changing the ubuntu version to a lower version. This requires a lower configuration. someone suggested only installing the command line, in this way, the configuration needs to be lower. some people say that the VBOX is better (in fact, it is not stable, but also ruled out), and then the lower version of Ubuntu, unfortunately, it is really slow. Just install the command line method. for a bird in my pure vegetable color, it is cancel directly. Www.2cto.com because the virtual machine is not only slow to use, but also the installation is slow, so a day has passed since the various attempts were made. But I still feel something rewarding, isn't it really Ah Q. Today, my summary is: (1) I know two kinds of virtual machines. they are very popular, but I think they still need to be improved. they are really slow, which makes me such an acute crash. Www.2cto.com (2) has known the Ubuntu graphic interface and simply implemented it. I don't even know where the command line interface is? Completely 720 degrees no direction... it's useless to worry, too much food is too white, a variety of tips... (3) after reading the image of Ubuntu on the surface and comparing it with windows, I want to laugh. what is the difference? Time above, window size in the upper left corner, applications similar to the taskbar on the left, a variety of Office software, the default Firefox browser. Is it a big success? (4) What is the most important thing? I don't know if anyone is here.
