Installation Process:

1. first, use UltraISO to burn the image to the USB flash drive (you can choose to hide the boot partition when burning, and delete the packages folder. This folder is useless, and the size is quite large, because there is an image in the USB flash disk during installation)

2. Then copy the CentOS-7.0-1406-x86_64-DVD.iso image to the U disk. (Do not forget this step)

3. Change the bios boot sequence (that is, enable the USB flash drive first), then enter this interface, press the tab key

Set

Vmlinuz initrd = initrd. img inst. stage2 = hd: LABEL = CentOS \ x207 \ x20x86_64 rd. live. check quiet

Changed:

Vmlinuz initrd = initrd. img repo = hd:/dev/sdb1:/quiet

Note: generally sdb, because the hard disk is generally sda, it may be different, but it is generally sdb1 ..

Click press Enter.

PS: in fact, it can be directly installed without using ultraiso to burn to a USB flash disk.
