2. Problems and Solutions during ubuntu Installation

These problems are solved by myself during the installation process. I may encounter various problems during ubuntu installation. Here I will not mention them one by one. I will only provide a solution based on the two problems I encountered.

1. After wubi is installed and restarted, ubuntu installation remains in the "copying files" status without any response. Solution: In this case, the solution is to completely disconnect the network. During installation at home, the network connection is obviously disconnected under win7, but this problem still occurs, as a result, the installation on the train will be okay the next day. It may be because the network is not completely disconnected. We recommend that you unplug the network cable and unplug the router.
2. When entering ubuntu, the system prompts "Yes/serious errors found during disk check" solution:
(1) When you enter the Ubuntu Startup menu, select * Ubuntu with the cursor, and press the e key on the disk to enter the startup Item editing mode.
(2) locate with the cursor, find ro rootflag = sync, change ro to rw, and press F10 to guide the system according to the modified parameters.
