What is the AHCI mode? Switching from IDE to AHCI without reinstalling Windows How to turn off IDE mode in the bios
Hello, we would like to know how to select the correct mode for the hard drive so that it works as required.
This is especially true for medium-sized computers, which may select the wrong option. Ale about every incident, turn it around. I didn’t even think about it until my director found out.
Look closer to the right) To get started, you need to go into your computer's BIOS. On different versions of the bios there are different entry buttons, press del on computers and F2 on laptops. For your computer, it says press F2 (Del) for bios. Here's a hint about every mishap:
Features of activation of AHCI mode in different versions of Windows
Next, change the integrity of the backup image to 100%. This other backup image is not needed for the switch, but will provide additional protection at the time of operator interruption. If there is a problem, you are not guilty of using another backup image for updating. Please make a copy and use a copy to update. I've had an update operation through a bad disk, and the backup image was frozen. You can remove the original disk or remove it from the car.
How to enter the BIOS for different versions:

Once you are logged in, you need to look for the Sata Configuration parameter. You need to select AHCI mode.
However, if this is not the case, you may end up wasting your discs. Without getting around this, many profiteers are not aware of the cost of life. In this way, computer manufacturers try to avoid possible problems due to the complexity of hardware and software.
How do you know which mode the computer controller is used in?
This can be verified in many ways.
For whatever reason, the first method did not work, yet another method.
As you can imagine, these actions can theoretically lead to unnecessary consequences, such as the inability to start the operating system.
At the same time, let’s find out what these modes are:
Find out how to connect IDE and SATA:
IDE mode
The IDE (Integrated Development Environment) connector is an old connector (developed in the 80s), as can be seen in the picture, which was previously used for connecting hard drives, floppy drives, sit-roms, etc. what encouraged such roses. At that time, the popularity of this rose was extremely popular, and now it is very difficult to remember and change on old computers.
A video recorder is an electronic device that is used to record video and footage in the song area. VCRs are used both for security purposes and for special purposes - they also include cameras with camera technology. When the registry editor window appears, proceed to the next update.
Note. Do not delete or change the values of other entries that you do not know. What is the cause of these problems? Let me reveal the real truth and suggest a simple way to get around this problem. When you try to install your operating system, you will notice that the installation procedure has completed shortly and you will see a blue screen indicating your hard drive driver.
The SATA (Serial ATA) connector replaces the IDE for connecting devices that support these outputs. The advantages of the sata interface at speed are in temperature (on sata devices it will be lower), on weak screws you won’t notice the difference, but on stronger ides the interface will not provide much power, although you won’t even find them at the same time. 
Virus of the problem of madness. Everything can start again. The specification describes the system memory structure for hardware providers to exchange data between the system host memory and connected storage devices. In the right panel of the door, click “Start”.

Where it is easier to pass the cords themselves and take up less space. Various networks support HotSwap and HotPlug. I’m eager to replace it, which is handy on the servers. There is no need to re-engage or delete.
AHCI is the connection mode for SATA devices, and I have come to understand all the statistics. This mode of sata devices must be handled properly.

If you are looking for mercy and want to help with these efforts, to replenish your experience in the lower part of this stat. Which section, method, or task has instructions that tell you how to change the registry. However, if you change the registry incorrectly, serious problems may arise. Therefore, be sure to follow these crumbs. For greater security, create a backup copy of the registry before modifying.
Then you can update the registry if the problem has resolved. This behavior speeds up the process of starting the operating system. If you change the original drive to a disabled driver, you must install the new driver before changing the hardware configuration. This problem persists beyond just one cob. If the block that is being changed is not the control module, this problem does not arise.
In order for all your devices to work well, it is necessary to choose one (especially if you have no choice).
To get started, you need to select Achi, otherwise Windows won’t start for you! You can, first of all, try it, and it’s great for everything. I'll show you how to set the Achi mode on Windows 7.
How to turn on ACHI mode?
Please check for additional register.

We lost our savings and left. Now we are re-enabled, and our operating system is enchanted correctly. Finally, you no longer need to reinstall the operating system. A number of English terms called technologies require clarification.
Press start – vicont (or WIN+R).
Type regedit and press enter.
The registry editor will appear. Nyumu walks along the path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci
The Start value is changed (after setting 3, if disabled), to increase ACHI, set it to 0 (achi mode is turned off). And let's go to the registry.
You will also need some support on your chipsets. Now you have hardware support, but you also have to deal with software support. You must remember the installation process if you need to attach the driver diskette to the installer. This behavior speeds up the process of attraction.
If you changed the original disk to a new driver, you must install the new driver before changing the hardware configuration. This problem is no longer a problem than the mechanical disk. If the change is made on a disk other than the storage disk, this problem does not occur. Lest the evil end.
I’ll tell you right away how to change ide to achi in Windows XP, I still don’t understand. After sitting for 2 years, the terpene didn’t run out. (Purely logically, I can skip the need to change the drivers and install achi in the bios).
Let's go into the bios, as I said above, and find the Sata Configuration parameter (or something similar) for example:
We have shown that with a small reading of small blocks, there is a positive impact on the productivity of the hard drive. Looking at this, there is a significant decrease in the sequential transmission speed and, as a rule, the recording speed.
However, it may happen that after changing this option, the system will stop working. How can you work without changing the controller's settings? You can change the controller mode in the settings of the motherboard. The resulting drives are more efficient and can incorporate new technologies that increase productivity. How can I change it without causing problems with the system?
Select the AHCI parameter and your equipment will work as follows :)
You will need to go through the process of restarting your computer in Safe Mode so that the appropriate drivers are installed. Then you need to use the following command to reboot the computer into safe mode. In the Start menu you will find the Command Row function. Right-click on it and select “Run as administrator”. The command window is displayed in administrator mode. I will enter a command to put the computer in safe mode.
Now we check if the computer is in safe mode - it recognizes the new disk controller mode and installs additional drivers. Once the system starts, re-enter the command line in administrator mode and enter the command to delete the safe mode entry.
Just this day, when I found out, I persuaded the boss to throw all the old cartridges into the trash can.
Well, with a calm soul we stuffed all the boxes into our storage room and went to the place)
At the end, there were boxes under the table)
Restore your computer. This time there will be no blue screen. We offer specialized services for updating data on hard drives with logical, electronic, firmware and mechanical defects. Electronic defects may occur due to low power supply or improper operation of a hard disk; it does not appear in the bios and does not make any noise, it should be done in such a way that no one has been harmed.
Corruption of this area does not allow you to deny access to the data. These types of defects are detected through vibrational defects or deterioration to an excessive middle level, and perhaps through those that are victorious. To update the data in such a situation, you must fix the problem with the firmware, then you can cancel the data update. This type of malfunction can occur due to voltage fluctuations through voltage defects or incorrect wiring.
Now there’s a lot of space in the office...)
The power supply to change the AHCI mode to IDE is specified by those who need to check the disk programmatically or install Windows XP on a new computer or laptop. If you don't mix modes at this point, the device simply won't be able to install the distribution.
What is the difference between AHCI mode and IDE?
IDE is a 40-pin connector for connecting a hard drive (and not less) to the motherboard. In current devices such a rose is not used. Well, the IDE can be used on older devices. You may only need it in extreme cases, for example, for installing Windows XP or Vista. The transmission speed through such a connector is 1000 Mbit/sec.
After IDE on motherboards and hard drives, a new SATA connector appeared. Vin outshines his opponent with the flamboyant speed of his work. Represents AHCI mode for this robot. The speed of data transfer in this mode is 1500 to 6000 Mbit/s (depending on which SATA is selected I, II or III).
If the device has a SATA connector, it is better to use it because the IDE mode reduces the productivity of the hard drive. You can switch to a new one if you don’t have a driver for SATA installed on your PC, or if you need one.
How to switch from AHCI to IDE?
Depending on the motherboard model and BIOS firmware version, mode changes will vary.
- We are obsessed with the BIOS. If your PC is old, then go to Main mode and select Sata Mode or Configure SATA as. There are two options for selection: “IDE Mode” and “AHCI Mode”
- If the firmware of your BIOS is different, you need to know the “Security” section and remember to configure “Secure Boot” by setting it to “Disabled”.
- This adjustment can be made in the Boot section.
- Next, go to the Advanced tab and go to the System Configuration item.
- A new menu will open. Select "SATA Controller Mode". You can change AHCI to Compatibility (with new IDE firmware).
Please note that if you do not have a SATA Controller Mode partition, you will need to switch UEFI Boot to CSM Boot in that partition.
It is important to note that manufacturers of motherboards and laptops have greatly reduced the functionality of BIOS, and it is impossible to switch to IDE mode.
Proper computer operation is only possible if there is good interaction between the computer and the operating system. Technologies are developing, and the rest of the time there are more and more people in the hoarders' minds. Today's hard drives and SSD storage devices are much faster than they were in computers 5-10 years ago. To transfer data, a SATA interface is used, and through a storage device it is connected to the computer. The SATA interface operates in two modes: IDE and AHCI, and if you have a current hard drive or SSD installed, you can speed up your computer by turning on the AHCI mode.
What is AHCI mode?
As stated above, AHCI is one of the data transfer modes behind the SATA interface. Apparently, through the SATA interface you can transfer information at a speed of 1.5 to 6 GB per second. Maximum fluidity is achieved in AHCI mode, which may be subject to constant accumulation. In contrast to the IDE mode, the SATA interface is supported for compatibility with older hard drives.
For installations in the Windows operating system, the AHCI mode is always disabled when connecting storage connections to the motherboard via SATA. Through this process, the computer's productivity is wasted, and the disk's performance is limited programmatically. By setting the AHCI mode, you can increase the speed of your computer by 20-30%.
How to find out if AHCI mode is activated in Windows
Most computer users do not suspect that it is necessary to enable AHCI mode in order for computer productivity to become a priority. In this case, Windows will not always work with HDDs and SSDs, most recently in AHCI mode. To check whether AHCI mode is enabled in Windows, you need to do the following:
Restore respect: Also, the shortness of the list of devices that operate in AHCI mode may be due to the fact that there are old storage devices connected to the motherboard that do not work in the new mode.
Also check whether you can operate the SATA interface in AHCI or IDE mode through the BIOS. To do this, you need to restart your computer and press “Del” or F2 when starting up. Launch the BIOS, where you need to find the SATA Mode item and look at whether to install the AHCI or IDE option.
Important: As you noted in the BIOS that the SATA interface is installed on the robot in IDE mode, there is no need to switch to AHCI mode, as there will be no cost.
How to turn on AHCI mode in Windows
Microsoft has begun to support AHCI mode in Windows operating systems with Windows 7. You can also enable it in Windows XP by downloading the necessary drivers on the Internet, collected by enthusiasts, and installing them. However, it is important to note that this method does not always give an increase in productivity, and better yet, on Windows XP, consider using the AHCI mode and processing data through a standard IDE.
To enable the AHCI mode itself, it is enough to set the configuration option for SATA in the BIOS. However, it is necessary to do this before installing the Windows operating system, otherwise, if the computer is locked, you will see the error 0x0000007B INACCESSABLE_BOOT_DEVICE or you will enter the stage of permanent re-locking. Therefore, to switch the IDE mode to AHCI when Windows is installed, you need to make changes to the registry, below we will look at what you can do for each version of the operating system.
How to turn on AHCI mode in Windows 10
In the current operating system Windows 10, Microsoft did not provide any configuration that would allow support for the AHCI mode “on the fly,” as previously the SATA interface was processed through the IDE. To correctly switch to AHCI mode, you need to do the following:
After installing the computer, the Windows operating system prompts you to install the necessary drivers for working with AHCI mode, which is all you need to do.
How to turn on AHCI mode in Windows 8 and Windows 8.1
To switch the Windows 8 or Windows 8.1 operating system to a robot with AHCI mode, you need to carry out the steps in the command line. You need to do the following:
If the computer runs on an Intel CPU, you can use the company's standard utility, which allows you to carry out the necessary adjustments to switch Windows to work with AHCI. Try it like this:
Restore respect: Guidance is a better method only for computers with Intel processors; for AMD there is no such solution.
How to turn on AHCI mode in Windows 7
In the Windows 7 operating system, the method for enabling AHCI mode is similar to that in Windows 10. Here you also need to make changes to the Registry in this way.
Today we know a simple way - how to change the SATA mode from IDE to AHCI in the BIOS while still running Windows 7. Even those who have already tried to change this mode were able to get a blue screen of death at the first time Try out Vindy's obsession. If you decide to make changes to the Windows registry, we’ll get to that right away.
Just a short note: In the era of Windows XP and earlier, there were expansions of the IDE or PATA interface, which in modern motherboards is no longer needed only for use with older devices and systems. The current standard is SATA, various revisions of which vary in terms of bandwidth.
Yesterday I was at one of my clients and on one of my computers and had the chance to try out this method. There I was standing and running in ide mode of Windows 7. By choosing to convert it to AHCI without reinstalling, at the same time improve productivity.
Hey, let's get started.
Press Win+R and write regedit, press OK and the Registry Editor will open.
If you have, for example, RAID mode, then you may need an address axis in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV
You may see something similar to the one in the screenshot. We need the Start parameter, which has a value of 3. Please double-click on the parameter name.
When you click on a name, an edit window will open. Here you need to change the number to 0 (zero).
It looked like this. Press OK, save.
After our manipulations, the pouch value looks like this:
The remaining strokes have been lost. Now you need to restart Windows and go into BIOS, change the mode there to the required one.
When the computer is about to restart, do not miss the moment of entering the BIOS. Call it the Del key. On laptops there may be buttons F2, F10 or F12.
On the client’s motherboard, the item looks like Storage configuration, in the middle is the SATA configuration (compatible and enhanced) subitem.
You can see the Configure SATA as sub-item next to the value and press Enter. Select AHCI value
The completed item now looks like Configure SATA as. Press F10 to save the BIOS settings, then Enter and the computer will restart again.
And now the moment of truth has come!)
Windows 7 may normally become enchanted and, when enchanted, reveal new devices, for which you can carefully search and install firewood. It is possible, after all, to ask you to re-engage. Revisit yourself, it’s easy to get Windows.
This method was used in my case and visually the computer became faster.
