Windows 7 Installation

I. Question proposal

1. Install Windows 7. Select the driver you have installed. The drive has not been partitiOned, And you are prompted that the partition cannot be created.

2. The main board is the motherboard integrated with RealTek sound card, and the video card is NVIDIA. There is no sound after the system is installed, but the sound driver is normal, realTek's driving sound detection software can detect sound.

Ii. Problem Analysis

1. When partitioning a hard disk, the most common scenario is to create a primary partition, and all the remaining disk space is created as a logical partition, after a logical partition is created, it is the extended partition of the primary partition, and then the disk partition is divided from the extended partition.

Note that a hard disk can only have three primary partitions and 4th primary partitions cannot be created. This is the crux of Issue 1.

2. Check whether the video card is integrated with the sound output. Check which hardware is selected for the sound output of the computer and the NVIDIA audio output by default. The reason is that the RealTek audio card driver is installed first, install NVIDIA graphics card and NVIDIA audio driver,

NVIDIA audio output is used by default.

Iii. Problem Solving

1. Back up the data, move the partition again, and install win7 successfully.

2. manually set the device with default sound output to RealTek
