How to install multiple operating systems

1. Install 98 in XP system to become XP-98 Dual System
I. Prerequisites
You must have an active partition in the format of FAT32 (or fat) file system and a partition in the format of FAT32 (or fat) File System to install Windows 98. How to view the file system format of each partition on Windows XP: Right-click "my computer" --> Manage --> disk management, the file system format of each partition is clearly displayed here.

Ii. Install Windows 98
Generally, the sequence of installing a dual operating system is: first install a lower version of Windows, then install a later version of Windows, and finally install linux from 95-> 98-> me-> 2000-> XP-> 2003 -> Linux system.
We want to install 98 in XP system to become XP-98 dual system, in XP system directly install 98 is not acceptable. Windows 98 installation must be enabled in DOS or with a CD, and 98 is a XP-98 dual system in XP, note the following key points during the 98 installation process: After Windows 98 is started under DOS or with a CD, go to the installation directory

Select the installation directory. Windows systems do not advocate the installation of dual systems in the same partition, because the C disk has already installed the XP system, so 98 can only be installed on other disks, here we select the D disk. Click "other directories" to make it selected, and then click "Next" to display
The default installation directory is "C: \ windows.000 ".ProgramIt is detected that the operating system of drive C already exists, so change windows to Windows. 000) Here we need to install 98 on drive D, because we need to change "C: \ windows.000" to "D: \ windows ",

Change the installation directory to "D: \ windows" and click "Next" to continue the installation. The other processes are different from those of normal installation 98. After the installation is complete, the system is directly restarted and enters the 98 system. No dual-System Startup menu appears. Currently, the Windows XP system cannot be accessed. You need to repair the Startup menu.

Iii. Repair the dual system boot menu
1. Use the XP installer to load the boot menu: Go to the Windows 98system and put the XP installation disc into the drive (find the directory of the XP installation file and double-click setup.exe). The XP installer will be automatically started.

Click "Install Microsoft Windows XP". You must select "new installation" for the installation type and click the triangle symbol on the right of "installation type, select "new installation" from the drop-down menu and click "Next ", continue the installation: After the license agreement prompt, enter the serial number, check the disk, prompt whether to download the upgrade Installation File, copy the files required for startup, and so on, when the system restarts for the first time, the disc is removed (otherwise it cannot be started properly). The Boot menu is displayed during the first restart.

This is a key step. When you restart the system for the first time, the Start menu is displayed for 5 seconds. Here, select the first item "Microsoft Windows XP Professional" with the up arrow key and press enter to enter the XP system of drive C,
2. Clear the temporary files left by the installer: after entering the XP system, open my computer and drive C, delete all folders and files starting with $ and ending with $ ($ WIN-NT $, $ LDR $) that are left behind by the installer and are useless.
3. Modify the Startup Menu: Click Start> All Programs> attachments> notepad. Click notepad to start the Notepad program. Click file to open the file window, the Startup menu file is located in the C root directory. Therefore, click "my computer" in the open file window, and then double-click "Local disk C" in the main window ", in this way, all the directories and text documents under the C root directory are listed in the main window, and the boot file is not listed. INI because it is not a directory or text document. To list all directories and files in the C-drive root directory, you must click the arrow at the right of "file type" under the open window and select all files.
Then you can see the boot file in the main window. Click "Boot" and select it. The file name will be automatically entered in the "file name" field (if the boot file is set to hidden, you can directly enter "boot. INI), and then click "open" to open the boot file in notepad.

 

(Boot. INI is a text file that contains information required to complete the boot process. You can edit it in any text editor. Its location is generally in the root directory of the active partition (for example, c :\). The content of the screen menu that appears after the XP installation is completed is determined by it, but the boot. INI serves not only to provide menu options for users, but also to control the operating system boot process.
The following is an example of a 98 and XP dual operating system boot. ini:

 
[Boot loader] timeout = 3 default = multi (0) disk (0) RDISK (0) Partition (4) \ Windows [operating systems] multi (0) disk (0) RDISK (0) Partition (4) \ Windows = "Microsoft Windows XP
Professional "/fastdetect c: \ =" Microsoft Windows"
 

There are two parts: the first part [boot loader] contains the timeout rule and the default path of the operating system; part 2 [operating systems] contains the path of the operating system installed on the computer, where multi (0) is the sequence number of the adapter, and disk (0) is the disk parameter information, RDISK (0) is the sequence number of the disk connected to the adapter, partition (4) is the Partition Number, and partition is generally determined by the location of the XP installation, it should be partition (1 ).
You can enable "Start and fault recovery" under "2000" or "XP" to modify the default Operating System and countdown seconds. (right-click "my computer" and switch to the "advanced" tab, ). You do not need to edit the boot directly. INI file .)

 

 

The content of the boot. ini file is as follows:

[Boot loader]
Timeout = 5
Default = c: \ $ win_nt $. BT \ bootsect. dat
[Operating systems]
Multi (0) disk (0) RDISK (0) Partition (1) \ Windows = "Microsoft Windows XP Professional"/fastdetect
C: \ $ win_nt $. BT \ bootsect. dat = "Microsoft Windows XP Professional installer"
D: \ = "Microsoft Windows"

Here, change the content of the boot. ini file to the following:

[Boot loader]
Timeout = 30
Default = multi (0) disk (0) RDISK (0) Partition (1) \ WINDOWS
[Operating systems]
Multi (0) disk (0) RDISK (0) Partition (1) \ Windows = "Microsoft Windows XP Professional"/fastdetect
D: \ = "Microsoft Windows 98"

Click "file" in the notepad menu bar and point to "save" in the pop-up drop-down menu ".
Click "save" to save the changed content and close the notepad window. Now the Start menu has been modified. After restarting, the Startup menu selection screen appears.

So far in the XP system to install 98 system, become a XP-98 dual system has been completed.

 

Q: I installed Win98 on drive C and Win XP on drive D. Later I used a partition magician to separate two zones from drive C to install Linux, however, after Linux is installed, Windows XP cannot be entered and Hal cannot be found. DLL file. What is it? A: The cause is the boot. ini file. As mentioned in question 4, partition indicates the partition number. If the Partition Number is not separated from drive C, the Partition Number of XP is 2 (disk D). After partitioning, the Partition Number of XP should be 4, but boot. the INI file is not automatically changed. Therefore, when XP is started, the boot program still runs to the second partition to find Hal. DLL file. At this time, the second partition is already a Linux File. Of course, the system will prompt that the file cannot be found, so XP cannot be started. the solution is very simple, as long as the boot. change partition (2) in ini to partition (4.
