Win7 installation can not create a partition solution

and the same as before the official launch of Windows XP, system partition requirements (such as partition format and space size, etc.) have been a topic of interest to users, and related topics are also "; How can I not install XP? & rdquo;. In the Windows 7 era, similar topics and problems existed as well. During the installation process, partitions could not be partitioned, new partitions could not be selected, and partitions could not be formatted.
The problem that caused the system to fail to partition and install properly is not unique. For Windows 7, if you encounter it, you can't format it and re-create the partition. You may wish to refer to the solution described in the following article. .
Under normal circumstances, the Windows 7 installer will let the user choose the installation partition (Figure 1), but sometimes, the hard disk clearly has several partitions, the installer only recognizes the current partition (Figure 2).

Figure 1 Let users choose the installation partition of Windows 7

In fact, when the interface shown in Figure 2 appears, it is not that there is a problem with the Windows 7 installer, it does not mean that There is a problem with the hard disk itself. After clicking the “DriverOptions(advanced)” button in the above figure, the Windows 7 installer will let the user create a new partition (as shown in Figure 3, please note the difference between Figure 2 and Figure 3).

Figure 4 is to create a new partition according to the Windows 7 installation program:

Figure 5 is the situation after the new partition:

This shows that if you eliminate the problem of the hard disk itself, We don't have to suspect that there is a problem with the Windows 7 installer (if there is a problem, it is also common in pirated Windows 7 installer, genuine does not have such problems).
In addition, some users attribute this problem to "Windows 7 installer can not identify the hard disk partition", from the above solution, such a statement is also untenable windows7 system download.
Comment: It is necessary to explain to you that some users often choose to use the already installed system when installing the above system, or install Windows 7 using external hard disk, or install Windows 7 using PE. These methods are not impossible, but they are the easiest way. If you still can't solve the Windows 7 <Unrecognized partitions", &"Unable to create a new partition" when you use the above method, I recommend using the external hard disk and PE mode for installation.
