How to install a dual system

Sometimes we find it hard to choose between Win7 and XP, and we want to play their different advantages. In this case, the dual system will be a very good choice for us. So, how does the dual system fit? This topic will take the XP and Win7 dual systems as an example to explain how to install dual systems.

In general, we need to install the XP system before installing the WIN7 system. This way, the installation of a dual system can be very simple. If XP is already installed on the current computer, the installation of Win7 will be more casual. The simplest way to do this is to insert the WIN7 installation CD after entering XP, and run the Win7 installer so that Win7 can be as simple as installing normal software. Note, however, that you must choose a new installation instead of an upgrade installation. When selecting the target partition for the installation system, be sure not to select the partition where XP resides. Do these two points can be. When prompted to restart the installation, the dual system is a smooth implementation.

We can also reinstall the system as usual, before entering the XP system to insert Win7 CD-ROM, the CD-ROM drive to complete the installation of Win7, but also to choose a new installation, and select the non-XP partition.

It should be said that both of the above methods are simple. However, if the computer already has the Win7 system, and then want to install an XP system, how to put the dual system?

It is not possible to install the XP installation disk under WIN7 because Windows only supports the installation of the system to a higher version. However, we can boot the XP installation CD before starting Win7, and install XP with the normal installation steps of XP. Note, however, that the target partition of the system installation is selected as a partition that is not Win7. A more convenient and quick way is to use Ghost to restore the XP system image to the partition where the non-Win7 is located, which is a higher success rate (but this way to do the following repair steps under PE, because XP will not be restored to the C drive will probably not boot).

This way we will enter the XP system on boot. The work of the dual system has not been completed because our Win7 is missing. Do not worry. After entering XP, we download a small piece of software called Ntbootautofix (or Bcdautofix) (of course, it is best to have the system ready before you install it). After downloading, open the software and select "Auto Fix" to do it.

When we restart the computer, we can see the boot menu for the dual system. It can be seen that dual-system installation is not difficult. Now, we can experience Win7 's powerful entertainment features and XP efficiency at the same time!
