The pits encountered by the reloading system

Computer environment: Dual System (Windows7 32-bit +ubuntu14.04lts 64-bit), I re-install the system for several reasons:

1. I was in the Python library font, accidentally put the Windows system fonts play bad, do not know why Windows under the font has been shown strange;
2. Computer memory is 4G, if 32 bit is a bit wasteful, so want to reload a 64-bit windows7;
3. The most important thing is that the office2010 formula displays the problem, because recently in writing the thesis continues the formula, don't ask me why not try to reload word, because I have tried n times already.

First of all, the process of my tragic reload system, let everyone happy: from the students to take over 64-bit system, began to reload the system, everything seems particularly smooth (PS: nonsense, it is so difficult to install a system?) After the system was installed, I found my wireless connection was problematic, but the cable was OK. So I tried to install the integrated network card version of the Driver wizard, after installing the wireless driver, also prompted me not to install, then I was really drunk, then I tried several times, or tragedy. Well, from Lenovo official website (PS: My computer is Lenovo's) there download wireless driver to do it, after installation, or not, how is it? Impossible Ah, there is a system problem, try to reinstall back to 32-bit system, and then installed back to the 32-bit system, the result is wireless network can not connect, wired network. However, it is also a coincidence, in the Lenovo download driver, I accidentally more under a call LAN driver, I took a try to install the attitude, the result I can only hehe, unexpectedly good, not the reason that the WLAN driver said, I Mars, it turns out that they both drive to install can be. Well, then let me reinstall the 64-bit system, which is now 2 o'clock in the morning. Tragedy again, installation system select partition, sleepy full of I accidentally to delete the C disk, rather than format, and put the system to the D disk, my mother, my file can not be lost ah, finally I was lucky, this is all after I installed the system only realize things. Then I re-add the deleted hard drive, and then reinstall the system, before this has tried the wireless network problem, sure enough is the reason. OK, the fourth time the installation finally succeeded, the wireless network is also completed, after that is the installation of various software, and so on, we first put the D disk last installed here system files to delete it, at this time I encountered a Windows permissions problem, delete, said I am not system administrator, I faint, before also encountered this problem, are directly with the grinder to fix, but this file too much, the speed of the grinder slow ah, Google after the problem. Good sleepy, the computer simply ignore it, let it go to update all kinds of things go, I first go to bed, at this time already nearly 4 points (only by the hard seat of the train, I can be so late, this is really the first time), when I unplug the computer power cord moment, I realized that my computer battery was hand cheap I pulled out, The computer instantly stalled, OK, no matter, sleepy, sleep.

The next morning (PS: This day is Sunday), get up at eight o ' clock, start installing all kinds of software, all the software is almost all installed, I found that my storage driver how to die there, I still uninstall him reinstall it, nightmare again, the system automatically restarts after not to go, I really have a cheap hand , no way, start my fifth reload system ... System and a variety of software installed, then I did not immediately deal with the Ubuntu system boot problem, because I am so tired ah, rest. To this day, because to use Ubuntu and Python environment, so I need to reboot, I Google a bit of this problem, found a way to go into the Ubuntu installation CD and so on, in the comments I happened to see someone say directly with EASYBCD can be directly done, very simple , I decided to try it, and the result was really easy. Well, said too much nonsense, actually want to record this process, by the way in the process encountered some problems, and how to solve the record, although are some very low operation (PS: This cliff can not be called technology), but for the future I, or record it. You crossing, do not like to spray ha ~
