USB stick Installation Window7 and CentOS7 dual system steps

Steps:

First, install the Win7 system

Attention:

<1> set aside a certain amount of disk space after the installation, for Linux system;

The first partition of the <2> disk needs to be left to the Linux system, that is, a block of unpartitioned space should be reserved before the C drive, not less than 200MB;

Second, install the Linux system again

Attention:

<1> when you set up a disk partition, the/boot partition is set to the partition size reserved before the C drive, and the setup software automatically sets the/boot as the primary partition, installed in the first space

Third, add Win7 Startup items in Liunx Grub boot entry (requires networking)

Attention:

<1> when the Linux system is installed, when the host is started, only the Windows startup items of the Linux startup item are lost, and the Linux grub is used to load the Windows startup items;

Tools

Two USB drives: one installs WinPE for installing the Win7 system and the other for installing Linux systems;

Partitioning tool: The partition helper in WinPE;

UltraISO: Used to make the Linux image file into a USB flash drive;
