Multi-system installation

Multi-system installation
 
Many people have such problems. windows XP has been used all the time. With the emergence of windows 7, some users started to use it, but most users did not use it, since the compatibility with the software was just introduced, the compatibility is now quite good, and the difference with xp makes many users feel that it is difficult to use Windows 7, but they also feel that the Windows 7 interface is very dazzling, in addition, I want to try out windows 7 systems when I buy computers. This is a very tangled problem. Therefore, it is better to install dual systems. If necessary, you can also install multiple systems, such as windows XP, windows server 2003, windows 7, and windows server 2008. The following describes how to install multiple systems:
1. Hard Disk Partition Planning
Before installing the system, you need to partition the hard disk. If you want to install several systems, you need to divide them into several primary partitions, however, you can only have up to four primary partitions, three primary partitions, and one extended partition (you can have multiple logical partitions). You can also install the system in a logical partition. So the most important thing is to determine the size of the partition space required for installing each system. During partitioning, you can use PE to start the disk, the system disk with the partitioning tool, or a dedicated partition disk. You can plan the partition when installing the first system. When using the file system, it is best to select NTFS.
For example, windows XP: 20G
Windows 7: 30G
2. Install the system
Two cases:
If you have a lower version and a higher version, you can install them in sequence. You can use different system disks to install different systems into different partitions.
During the development of windows operating system products, you need to know the version level. The red color indicates the most commonly used system (User edition and Server Edition)

② Re-install or restore the system from a higher version to a lower version.
When you first install a higher version and then install a lower version, you will find that there is no higher version of the Startup menu in the Startup menu. You only need to fix the Startup menu.
(1) Use a tool to automatically fix the issue. This is the fastest and easiest way.
Common tools include BCDautofix and NTBOOTautofix,
Double-click to run the task, as shown in the following figure.
 
 
 

(2) manual repair, such as windows XP and windows 7
After windows xp is started, insert the installation disk of windows 7, start-> Run, Enter cmd, and press enter to go to the command line controller.
Input X:
Enter
X is the drive letter of your optical drive, so we will go to the X: directory.
Enter cd boot
Enter
Go to the boot directory of the CD
Enter bootsect/nt60 sys
Enter
Shut down all windows and restart the system. After the system is restarted, there is no dual-Start Menu, but the Windows 7 system is directly entered. Note: now we have switched from windows xp to windows 7, while windows xp and windows Vista both use BCD, which is much more advanced than windows xp's boot. ini. Haha.
Close the User Account Control in the control panel and run the command prompt as an administrator (this item is not run in the default start menu and can be directly entered in the search)
In the command line controller, we execute the following commands in sequence (I do not explain what each command means, directly bcdedit /? ):
Bcdedit/create {ntldr}/d "Windows Xp"
Copy the code Bcdedit/set {ntldr} device partition = H:
Copy the code. Note that H: The drive letter of the hard drive where XP is located in Windows 7.
Bcdedit/set {ntldr} path \ ntldr
Copy the code Bcdedit/displayorder {ntldr}/addlast
Copy code
So far, our dual-boot menu is complete, and then we checked our XP system boot problem and came to H: (according to your own situation, this is the drive of your XP system ), click organization> folders and search options> View> to remove the √ before hiding the protected operating system files (recommended) and set the hidden files and folders to display, check whether the root directory contains ntldr, NTDETECT, and boot. ini, CONFIG. if there are four files such as SYS, you can copy these four files on windows XP's computer. Note that you need to hide the protected operating system files in windows XP (recommended) remove the previous √ and set the hidden files and folders to be displayed. NTDETECT is not required in the pirated system. copy the file and paste it to your H: \ (the drive letter of the XP drive in Windows 7). I have packed three required files, after downloading and decompressing the file, you may not be able to see it. Remove the √ before hiding the protected operating system file (recommended) and set the hidden file and folder to display. To.
Now, restart the system and check that our lovely dual-System menu is out. The test is normal.
