When you reinstall win7, the system prompts "the required CD/DVD drive device driver is missing"

Many of my friends are doing this. They have been using their computers for a long time and are too lazy to clean up and fix them frequently, or because of occasional poisoning, poor system operation or even crash. During the past few days, I have been searching for and downloading materials on the Internet, making my own book messy, and I am too lazy to take the time to fix it. Today, I have finally gone through a complete strike.

In the face of this situation, we have always reinstalled the system. However, there was a problem that was never encountered during the reinstallation today. After the system disk is ready, enter the installation interface and pop up "the required CD/DVD Driver driver is missing ......" . For example:

At this time, when you see the literal meaning of the prompt, you may think about whether the computer lacks a driver. In fact, if you click "Browse, the partition of the local hard disk and the corresponding drive letter (such as) are displayed, so we can preliminarily determine that this is not a lack of driver program for the drive device.

The Windows 7 system is installed by loading a Windows 7 PE system to guide the installation. The PE system is the Windows 7 kernel, and we use a USB flash drive to guide the installation, it is not possible that he does not recognize the USB flash disk. The reason may be that the USB flash disk is recognized in the PE system.

In this figure, we found a problem, that is, although we can see the local partition, but it does not show the USB flash drive we inserted. This is why he prompts that the CD/DVD has no driver, now the problem is found, because no pe system does not recognize the system in the USB flash disk. Although the boot is successful, the real system is still in the USB flash disk ......

At this time, the solution is to return to the original interface (insert the system disk into the first interface), pull out the USB flash disk, and then change the port, plug in again (especially when you have both USB and USB interfaces on your computer, it is better to change the type of port ). Wait a moment and proceed step by step again. Can you see the following familiar normal interface!
