Change the hard disk mode in Windows 7 system

There is not only one hard disk mode under the system, so if you change the hard disk mode first, you can change it. However, many people don't understand why they need to change the hard disk mode. For example, the hard disk mode in Windows 7 is changed from IDE to AHCI. Is there any benefit?

Although Windows 7 supports AHCI mode built-in, if you install Windows 7 in IDE mode, you dare to set the hard disk to AHCI directly in the BIOS, it will be blue screen

Steps:

The Intel chip driver intel_inf_9101013beta.zip mentioned in the first part is installed? If it is not installed, please install it first.

Let's talk about how to install Windows 7 in IDE mode and how to adjust it to AHCI mode without blue screen. Simply put, two steps: change the registry, change the BIOS settings.

Microsoft said this when it comes to this blue screen failure ——

<;In the BIOS setup of a Microsoft Windows Vista-based computer, change the serial advanced technology attachment of the boot drive ( SATA) mode to use the Advanced Host Controller Interface (AHCI) specification. then restart your computer. In this case, you will receive the following error message: STOP 0x0000007B INACCESSABLE_BOOT_DEVICE”

Rely on, blue screen is blue screen, and what is said to be “received error message”!

To resolve this issue, enable the AHCI driver in the registry before changing the SATA mode of the boot drive. To do this, change the value of "Start" in HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\Msahci to “0”. To be more specific, here are the steps:

1. Quit all Windows-based programs.

2. Click “Start”, type regedit in the Start Search ” box, and then press ENTER. \\\\

3. If the “User Account Control” dialog box is displayed, click “Continue”.

4. Locate and click the following registry subkey: HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\Msahci

5. In the right pane, right-click “Name” “Start” in the column, then click “Edit”.

6. In the "Value data” box, type 0, then click “OK”.

7. On the "File" menu, click “Exit” to close the Registry Editor.

After changing the registry and restarting the computer, please set the hard disk mode to AHCI in the BIOS and then enter the system.

You will find that Windows 7 automatically installs several drivers after this startup, and then asks to restart the computer.

AHCI mode has certain advantages over IDE mode, but most users' hard disk mode is still more IDE mode, so the mode conversion must be done manually, remind everyone It is necessary to pay attention to the details of the operation.
