Migration from windows 7 to ubuntu 12.04

The process of migrating from windows 7 to ubuntu 12.04 has been working in windows 7. Recently, I need to write some automatic scripts and try to write dos batch. I can't write it anymore (nausea and nausea ). Cygwin is installed, which is inconvenient to start. Decided to return to the lovely linux environment. I am too lazy to buy and burn a CD. I can directly use wubi to install ubuntu on a windows hard disk. After using wubi ubuntu for a few days, you can feel it at first.
Gradually the problem arises: Sometimes the speed is slow, sometimes the machine crashes, sometimes the machine cannot enter the graphic interface, sometimes the graphic login interface, how can not be logged in (except with guest) at the beginning, I had to endure it. It was not until yesterday that the graphic interface could not be accessed. The graphic interface www.2cto.com cannot be logged in (can't log in to gui with administrator account). This is the case: After you enter the password, the graphic interface will flash into a command line, an error is displayed in 0.5 seconds, and then the graphic logon interface is flashed back. Ubuntu12.04 uses lightdm as the logon interface. Is this possible? So: The Ctrl-Alt-F1 to switch to TTY1, installed after logging on to the agent. During the installation of WordPress, you will be asked to enable the logon interface? (Tty1 may not support Chinese characters. I can see small boxes in tty1, but there is no pressure to answer this question.) Of course, we should choose the target type. Sudo reboot can now log on to the graphic interface. Although the WordPress logon interface is not highlighted by lightdm, it is better to go in than to go in. Www.2cto.com slow (slow) on my SSD + i5cpu + 8G ddr3 ram, there is a time to card, it can't be said. I think about it with my knees, probably because it is installed in a virtual image, which slows down file access. So I plan to move to the physical hard disk. Disk partition. I only made a root zone for ubuntu. If you want to sleep, it is said that you still need a swap area. Perform this step: https://help.ubuntu.com/community/migratewubiand now my ubuntuis running fast.
