How to make Linux run on a USB drive

Linux also has a different version, although each has its own advantages, but its core is similar. To recommend this operating system is: Ubuntu. First download this system installation software, ISO file Ubuntu11.10 version

Install the downloaded ISO installation with two methods: one is to use the USB disk to install the USB drive; Another method is to carve the ISO file into a CD-ROM and install it on a USB disk. Focus on a U disk to install the U disk.

To use a U disk installation, first have to install the ISO file to the U disk, you can not directly copy the ISO file to the U disk, to use the UltraISO file to install. Software can be downloaded online. Open the Ubuntu11.10 file with the UltraISO software.

Then use the UltraISO software "boot": Write to the hard disk image;

Select USB-HDD and click Write. Exit the software when finished.

Use a U disk to install Ubuntu. The computer into the COM settings, the U disk as a startup disk. After saving to restart the computer, the U disk is acting as usb-cdrom. After entering the interface, you can choose to install Ubuntu to the hard disk or install to the U disk. If you do not install, you can also surf the internet, or do other things. But anything you save is lost after it restarts, and the interface and files are all restored to their original state. The only advantage is not afraid of the virus. If you want to be like windows, you'll have to install it two times. Of course, you can also install in Windows, install a new startup directory in XP, but affect the performance and speed of Ubuntu. The best way is to install it alone.

Separate installation to partition requires two zones: one is a virtual memory area (swap), also known as a swap area. Size is 150m~1200m, 1000M is recommended. Another primary partition, greater than 5 G. After installation, the system files are approximately 3g, and the files will be upgraded and downloaded later. You can install Ubuntu after two separate points. I used a 8G SD card, divided into three areas, in addition to two Ubuntu partition and a 1.5G FAT32 format partition, mainly for Winodws, but also with Ubuntu for file Exchange and download the space to store files. When installing Ubuntu, it is best to disconnect the hard drive, which is safe.

You must set the username and password during the installation process, or you can choose to automatically enter the password at startup. Passwords must be kept in mind and used when upgrading and installing files. To choose a language for installation, it supports many languages, as well as Simplified Chinese. Of course, after installation can also change the language on the web. Installed Ubuntu is best to upgrade first.

In Ubuntu, you can directly run Word, Excel, and Power point in Microsoft Office. Also can not hard drive, I use the notebook computer is Acer 1810TZ, in the trip after disconnecting the hard drive can also save electricity, become a veritable without hard disk computer. The computer's battery is extended a lot of time, and because there is no hard drive is not afraid of bumps. The performance of the whole machine has been greatly improved.

Ubuntu 11.10 also supports Bluetooth and WiFi internet and camera features without reinstalling. People who like the Wubi can be called directly. The browser's interface is also very good, especially under the tools of the ' Privacy browsing ' function, so that you can browse any page will not leave traces. This is the same as the IE8.0 function. If someone also likes the Ubuntu system, you can communicate.
