Dual system installation order
Q: I plan to install multiple systems in a computer (Windows 9x/XP), what is the order of the installation? ? What should I pay attention to?
A: Generally speaking, the installation order is from the low-level version to the advanced version, that is to say, first install Windows9x, then install WindowsXP under Windows9x system. The advantage of this is that the system can automatically generate the boot selection screen.
The following points should be noted:
1. Each system should be installed in a different partition. The best arrangement is: install Windows 9x on the C drive and Windows XP on the D drive.
2, for different systems to choose a different system file format. For Windows 9x, choose FAT16 or FAT32; for Windows XP, it is best to use NTFS format, so the system potential will play better.
3, when installing Windows XP on Windows9x, you should choose "New installation", do not choose "Upgrade Installation".
How to install a low version of the high version
Q: My system is Windows XP, now I want to install a Windows 98, how to install Windows 98 while keeping Windows XP, do a dual system?
A: Because Windows XP can not directly install Windows 98, you must first start the computer with the Windows 98 boot disk (of course, the prerequisite is to start from the A disk in CMOS), and then install Windows98 to a partition other than WindowsXP. . After rebooting the system, you will find that there is no dual boot menu and the system goes directly to Windows 98. It doesn't matter, just follow the answer to the next question. After the recovery, delete the files ending with “” characters in each partition of the hard disk and delete the files ending with “”.
Restore selection menu
Q: I installed Windows 98 plus Windows 2000 operating system. Due to the wrong operation, the boot.ini file is deleted. Now when I start the computer, "boot.ini is illegal" I did not choose the menu, but went directly to Windows 2000. How can I recover?
A: First adjust the boot sequence to CD-ROM boot in the BIOS, then put the Windows 2000 installation disk into the CD-ROM drive. After the auto-loading of the installer, the system will ask you whether to re-install or repair, do not care about it, and exit directly. Finally, in CMOS, the boot sequence is changed to hard disk boot, so that the boot menu will appear after booting again.
