WillISOThe image file is made intoUSB disk

1, Microsoft Windows

Making USB Live disk with the Universal USB Installer, UNetbootin, WinSetupFromUSB, LinuxLive USB Creator, YUMI (Your Universal Multiboot Integrator) and so on, Choose one of making USB Live.

2, The Linux distribution

Insert your USB flash drive

$dmesg //To view the USB-Disk information

$su - //Login root

#findmnt /dev/sdb //To view mount, findfs

#umount /mnt/iso //The lack of load

#dd if=~/Downloads/CentOS-7.0-1406-x86_64-DVD.iso of=/dev/sdb bs=512k

If TYPE is not VFAT (such as TYPE= "iso9660"), the first piece of data to clear USB Flash Drive.

#dd if=/dev/zero of=device bs=1M count=100

Tips: If you perform this step, it will destroy all data in USB flash drive without warning. Please make sure you specify a USB storage drives correctly, and to identify any you want to keep the data does not contain the flash drive.

3.Collection of hardware information

Hardware setup now release the recognition ability in Linux are relatively strong, if not inquire what hardware information, install the operating system also does not have what big problem, but for the very new notebook computer hardware and so is special equipment, or suggest a query related hardware information in the network, to ensure that the hardware can driven by the. Here are several possible need to focus on the hardware, for any kind of release all need to pay attention to the following questions.

(1)Motherboard chipset support.

In particular, most of the current user is the motherboard sound card, before installing the system should consider supporting the Linux kernel on the motherboard chip sound function.

(4) Graphics card. The current mainstream graphics cards are supported, If needed, Look at the graphics chip manufacturers, models, memory size can be the basic., If you want to save trouble, Can consider to choose the performance while not strong, But open source driving stability and performance of the best Intel integrated graphics, And the pursuit of high performance graphics users can consider NVIDIA chip and driver in the future use of the official, To get 3D better, ATI/ADM graphics currently Linux driver is not ideal, But AMD has opened up the technical specification of chip, Will be a good support for open source drivers of the future.

(5)Other peripherals. USB keyboard and mouse can generally be supported, mobile hard disk box at the bottom of the minority may not be supported, cameras, small hardware most can be supported, the other is some notebook computer, need to look at.

In order to be prepared against want to examine the information, or more, in addition to the Internet search and ask their friends, experience of using Live CD is also a very good way.
