Because many servers already do not belong to the CD-ROM, recently tested the use of USB flash drive for Linux system installation, the process is relatively simple, need to pay attention to the following:

1, find a Linux host, insert a USB stick, execute fdisk-l, identify the U disk.

2. Upload the Linux system image that needs to be installed to a directory of that host, this is/home/networking
