  3 ways to install XP and win7 dual systems

  1. First of all, you need to prepare a main partition for installing the XP system. It is recommended to use the disk manager to create a main partition with a capacity of not less than 10GB in the Win7 system. Then start the computer with the Win XP installation CD and install it. The installation method is similar to the installation of the XP system.

  2. Install XP first, and then install Windows 7. It's better not to do the other way around, otherwise XP will not overwrite the boot manager of Windows 7, which will be more troublesome. In a word, follow the installation principle of "old version to new version".

  3. There are two ways to restore the boot menu: use software (bcdautofix, easybcd, VistaBootPRO, of which easybcd needs the support of Microsoft.NETFramework0 to run under XP ) Or use Win7 to install the CD to repair.

  4. First of all, it is strongly recommended to make a dual system, but if only a separate system is made, it can also be installed according to the following methods. Note: The so-called dual system refers to the installation of two different systems that run separately, do not interfere with each other, and are completely independent, such as a WinXP and a Win7 or Win10.

  5. Virtual optical drive (ghost image installer), partition magician, which is integrated in Chenfeng PE.Now I will teach you how to pre-install ghost XP system 1 under win7, set the USB flash drive as the first boot item and enter the PE system.

  What is the difference between a distributed operating system and a network operating system?

  1. The difference between network operating systems and distributed operating systems is: (1) distribution. The processing and control functions of distributed operating systems are distributed; although the network operating system has distributed processing functions, its control functions are concentrated in one or some hosts or network servers, that is, the centralized control method. ( 2) Paralismality.

  2. The design ideas of distributed operating systems are different from that of network operating systems, which determines that they are also different in structure, working methods and functions.

  3. The communication function of the distributed operating system is similar to that of the network operating system. Because the distributed computer system is not as widely distributed as the network, and the distributed operating system also supports parallel processing, the communication mechanism it provides is different from that provided by the network operating system, which requires high communication speed.

  4. What are the types of operating systems? The types of operating systems can be divided into batch operating systems, time-spliting operating systems, real-time operating systems, network operating systems and distributed operating systems according to the working mode.
