Install Win7 and how to use XP often, dual system installation method

You should know that the current system installation disk is divided into two types: the original (installed version) and the ghost version, now the mainstream is the ghost version, why? Because he is installed very fast, this is unmatched by the original system, and it also integrates common drivers and common software, which is very convenient. However, the ghost version has a shortcoming. This is reflected in the installation of dual systems. It can only be installed on the C drive (primary partition, active), and we can only set one active partition for the active partition, not two. And the main partition can only be set up to three, which is difficult to install pre-installed genuine win7, because many pre-installed genuine win7 has three main partitions, one boot partition, looks like more than 100 MB, a restore partition, there are several G, a win7 system partition. There is a problem here: how to install a ghost system under the installed windows system.
Here I will demonstrate the installation of ghost Windows XP system under PE with the existing USB flash drive under the existing win7 system. The core idea of ​​the installation is: hide the previous win7 disk first, create another system partition, let the ghost installer mistake this for the C drive, install the XP and then use the software to repair the dual system boot.

3, windows XP system image (.iso) or system ghost file (.gho) (decompress the image file with decompression software, the largest file inside, generally about 700MB) This is recommended to use the image file. Because there are too many choices, you can choose from the readers. Note that it is best to choose the system image with AHCI driver. The reason is that some new notebooks default to AHCI hard disk mode, while xp only supports IDE mode. In this case, installing XP will be blue screen. .
