Nowadays, the newly purchased brand is pre-installed with Windows XP. Maybe you still miss the previous Windows 2000, or because of some needs, you must install Windows XP and Windows 2000 dual systems. Although multiple operating systems can be installed on a computer, others will generally tell you, you have to install from low versions, that is, if you want to install Windows XP and Windows 2000 dual system, you must first install 2000 , Then install Windows XP. If you don't want to do this, then look at this article, teach you a good way to install it directly.
You must first do some preparations:
The first is the installation disc of Windows 2000. It is also necessary to have at least two hard disk partitions, when installing dual systems, it is not recommended that you install two systems into the same partition, which may cause a lot of trouble for future use. If you are all done, then continue our installation.
Suppose your Windows XP is installed in the C drive, you want to install the Windows 2000 to D disk, then just run the installer with Windows 2000, you can run the installer and install it to the D disk, but then this is installed after the double boot menu will Failure, can only go to Windows 2000. The reason is this:
In the startup of the Windows NT system, many important system files are used, and the XP's NTLDR and NTDETECT.COMs are replaced with two files in Windows 2000 when installed on the machine installed. The same name file, and the two files in Windows 2000 cannot boot Windows XP. So our repair is the file that is covered by Windows 2000 with files in Windows XP.
These two files are saved in the root of the C drive, but they have the default implicit, system, and read-only properties, so you can't replace the general method, and first to release their implicit, system, and read only Attributes. The method is this:
Enter in Windows 2000, input separately
Attrib C: \NTLDR -S -R -H
Attrib C: \ NTDETECT.COM -S -R -H
Press the Enter key after the input is completed. At this point you have completely released the system, implicit, and read-only properties of these two files. Now copy these two identified files from the I386 folder of the Windows XP installation CD to the C drive root directory, and override the original file. At this time your dual boot menu has been restored. However, we can hide the two files, the method is to enter:
Attrib C: \NTLDR S R H
Attrib C: \ NTDETECT.COM S R H
This will re-give that two file systems, implicit, and read-only properties.
Start and take a look, your double start menu is completely normal.
