How to set up the mini computer to boot from the hard disk

Our mini computers are usually booted from the hard disk, but when some need, it may be set to boot on some peripherals (such as USB flash drive or mobile hard disk). In this case, the boot has a non-hard disk boot, how to going to modify the hard drive to boot?

First of all, if we open a mini computer, we need to restart the mini computer at this time. If you don’t have a mini computer, just press the power button. (PS: Try to close all programs, this will minimize the damage to the mini computer)

After restarting, you must pay attention to the English of the page on the boot page. At this time, you need to remember to enter the BIOS setting keyboard button (PS: Different computer’s entry BIOS settings are different, you must not press it randomly, according to the boot page to determine.)

At this point, enter the BIOS setup window, we need to find him “Advanced BIOS (Advanced BIOS function) options”, look carefully, you will find, and then double-click it to enter a new page. Of course, unlike computers, you need to observe them carefully. It is best to check English at any time.

In the new pop-up window, we need to find the “Boot Devlice priorfty” carefully, this time still double-click it to enter the new page. If not, you will need to find the boot, and the Enter key will come out of the new window.

On entering the new page, we can see the three items “1, 2, 3” arranged in order (some BIOS is 1st Boot Device; 2nd Boot Device; 3th Boot Device), which means “the first start” The second item starts and the third item starts. You can look at the picture carefully. (This computer is represented by numbers.)

Once found, we need to modify according to the prompts on the page, set the order to “hard disk – HDD; mobile device is USB; CD-ROM drive is CDROM”. (PS: According to the picture, we can find that the hard disk of this computer is very hdd0, according to the prompt at the bottom of the page and the help on the left.)

After the setup is completed, we generally use F10 to save (there is also a prompt at the bottom of the PS page). In the pop-up dialog box, we select or enter “Y” to save. At this time, the computer will restart automatically, and our settings will take effect. (This computer can hit the Enter key directly in the yes place.)

How to install dual Operating System on the minicomputer

Dual Operating System at the time of installation, the two OS are installed in different partitions, and the rear installed OS doesn’t cover the previous OS. And each individual OS has its own partition format that does not cause conflicts. After installing the dual OS, there is a multi-boot selection menu at boot time, you can choose to enter that OS. In the current state, only one OS is running and cannot be switched at will. If you want to enter another one, you have to restart and re-select. Below, we will tell you how to install WIN7 under WIN10.

Key Point: When installing dual OS, it is installed from big to small, that is to install win7 on the basis of win10. If it is reversed, the win7 will be overwritten by win10.

Step 1: Open your win10 OS and prepare your win7 installation package, then the system directory in win10 OS (It’s your C drive) according to: local disk C→wwindows→Boot→EFI→find bootmgr.efi Copy the file.

Step 2: In your win7 installation package: efi → microsoft → boot as shown below. No bootmgr.efi file in the folder.

Step 3: Copy the bootmgr.efi in the second step to this directory, and then change the name to bootx64.efi, which is the pre-order step.

Step 4: Click setup.exe in the win7 directory to install.

Step 5: Then pop up the following form and choose to install now.

Step 6: As shown below: enter the installation.

Step 7: Choose not to get the latest installation.

Step 8: Select Accept Terms: Click Next.

Step 9: Choose a custom installation.

Step 10: Choose your installation directory: Click Next.

Step 11: Enter the installation, do not perform any operations on your minicomputer during this period, the system may restart several times, but it doesn’t matter.

Step 12: After all the installation is completed, enter the settings of the running part of the win7 OS as shown below.

Step 13: After setting, enter win7.

Step 14: Then when your computer restarts, there will be two systems to choose to start.

The above is how to install win7 dual OS operation under win10.

Ten skills of mini computer you shall master

In fact, a lot of cumbersome operations on the computer can only be done with just a few keystrokes. If we don’t understand these shortcuts, when the computer encounters problems, it will often make people very crazy. In this issue, I will share 10 for you. The most common use tips.

Tip 2: Quick access

Quick access shortcut: Win+E

Sometimes we have a lot of icons on the desktop, it is difficult to find “this computer or computer”, and even some users have no “computer or this computer” icon on the desktop. At this time, we can press the key on the keyboard and then press the E key to open the resource manager of the computer directly.

Tip 3: Display the desktop

Show desktop shortcuts: Win+D

Sometimes the computer gets stuck or opens a lot of things. If you want to quickly return to the desktop, we can press the windows button on the keyboard and press the D button to display the desktop directly.

Tip 4: Cancel

Undo shortcut: Ctrl+Z

There is no regret in life, but computer operation can regret it. The shortcut key Ctrl+Z can help you undo the previous step, which can be used in many applications.

Tip 5: Refresh button

Refresh shortcut: F5

F5 is the refresh key used to refresh the contents of the current window in the IE or Explorer. This is a very convenient shortcut!

Tip 6: Quick start

Quick start shortcut: Win+R

This shortcut is a native feature of Windows that comes with everything from XP to Windows 10. After using this shortcut key, you can open the system search, which is a relatively quick command input method. The system will pop up a small window for you to enter the command. After the carriage return, the command will be executed immediately and the run window will be closed.

Tip 7: Magnifying glass

Shortcut: Win + +

If you can’t see the text on the display then you definitely need an amplifier. The shortcut key windows++ enlarges, whether it is a browser or word, ppt, excel can use this shortcut to zoom in. You can also use the CTRL+ mouse wheel.

Tip 8: Switching tasks

Shortcut: Win+tab

This shortcut key is similar to alt+tab. After using this shortcut key, you can switch tasks, making the switching task faster and more efficient, and win+tab can click the task compared to alt+tab. Choose the task you want to do faster.

Tip 9: Quick Screen Recording

Press Win+R, type psr.exe and click “OK” to open the recording function that comes with Windows, and then you can start recording. After the recording is completed, a save dialog box will pop up, where we can save the recorded file as a zip archive. After extracting the zip file, we see that the recorded file is not a video file, but an MHTML report file. Open the file, we see that we have a screenshot of each step on the screen, and highlight the mouse click area, and support to view as a slide, and finally generate a compressed MHTML report file to send to the help object Recorded issues can support slide shows.

Tip 10: Permanently delete

Permanently delete: shift + delete

Shift + delete delete is unable to restore deleted files using the restore operation, that is, the files deleted by this method are not through the recycle bin.

How to improve the Minicomputer Boot Speed?

It is a very common problem that the minicomputer is booting slowly. When the computer is turned on, some default software will be started. There are many factors that affect the speed of computer booting. In this issue, we will explain how to speed up the minicomputer booting.

First, disable the useless start-up items:

Disable the programs that are not needed or rarely used, which can effectively speed up the boot.

Operation method: Right click [task bar] to select [Task Manager], click [Start], and select the corresponding program.

Second, modify the registry to reduce boot pre-read items:

Super pre-reading is very intelligent, can improve system performance, speed up program startup, and is essentially to improve memory utilization, make full use of memory to improve system performance without affecting the operation of other programs.

Operation method:

1. Press the [Win+R] key on the keyboard, enter [regedit] and click [OK].

2. Expand step by step in the registry to the following directory location: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Memory Management\PrefetchParameters

3. Double-click “EnableSuperfetch” and modify its value to “3”, which can effectively speed up the boot.

Third, through the installation of third-party tool software to help us optimize the boot project:

The computer is equipped with security software such as “XX Computer Manager” or “XX Security Guard”, and these third-party security software basically have the function of boot acceleration. Therefore, we can use them to help us optimize the computer boot items to save the boot time.

Key points: This kind of third-party software itself is also the boot-up item, which will take up the computer boot time. And the more such software is installed, the more cards are stuck, the slower the boot is, and it is enough to install at most one.

Fourth, computer cleaning:

Dust in the computer can easily accelerate the aging of the components, resulting in slow operation of the hardware, and even some of the poor contact can not be started properly. For example, if the fan is not cleaned in time, the temperature of the computer is too high, and it is easy to start the computer slowly. It is also necessary to clean the computer in time.

How to turn off ACPI on your minicomputer

ACPI is actually a power management standard. ACPI is an acronym for Advanced Configuration and Power Interface. It is generally translated into advanced power management. It is a power management standard jointly developed by Intel, Microsoft and Toshiba.

What is the use of ACPI?

   ACPI is part of Windows (starting with Win98). It helps the operating system to properly control and allocate the power of computer hardware devices. With ACPI, the operating system can shut down different hardware devices as needed according to the actual situation of the device. For example, in Win7 or Win8 system, when the system sleeps, the system stores the current information in the memory, and only keeps the power of several key components such as memory, so that the computer is in a high power saving state.

ACPI is powerful, enabling device and processor performance management, configuration/plug-and-play device management, system events, temperature management, embedded controllers, and SMBus controllers.

ACPI indicates that the advanced configuration and power management interface ACPI can achieve the following functions: 1. The user can make the peripheral switch at the specified time; 2. The user who uses the laptop can specify that the computer enters the low power state under low voltage to ensure Important applications run; 3, the operating system can reduce the clock frequency when the application time is not high;

4, the operating system can allocate energy according to the specific needs of peripherals and motherboards; 5, when no one uses the computer can make the computer into a sleep state, but to ensure that some communication devices are turned on; 6, plug and play devices are inserted

How to copy large files to a USB flash drive?

Do you have such an experience? I want to copy a large file to a USB flash drive. It is obvious that there is a considerable capacity in the USB flash drive. When copying, it always prompts that the file is too large to be transmitted. Today I will teach you how to copy large files into a USB flash drive. Two methods are introduced. The first method will lose the data in the USB flash drive. The second method will not lose the data in the USB flash drive.

Key points: The format of U disk is commonly FAT, FAT32, NTFS and exFAT. The default format of the USB flash drive is FAT32, and the FAT32 format does not support storing a single file larger than 4G, so we only need to convert the format of the USB flash drive to NTFS.

The operation method is as follows

Method 1

1. Right click on the U disk and select “Format”

2. Select “NTFS” at the file system.

3. Click on “Start”

4. Click “OK”.

5. Click “OK”.

6. Copy large files to the U disk now.

Key points: This method is easy to operate, but all the contents of the USB flash drive will be cleared when formatting.

Common ways to solve Minicomputer blue screen

In the process of using the computer, the most annoying color is the “blue”. Sometimes the sudden blue screen is just a crash. In fact, the computer blue screen is also a common phenomenon. There are many factors that cause the blue screen of the computer. Today I will give the corresponding solution for the common blue screen of the computer. I hope that it will help everyone, and I hope that these codes will give you some inspiration, so that you can prevent the blue screen of the computer in time.


Cause analysis: The CPU is too overclocked.

Solution: Start the auto-repair program and restore the CPU to the factory frequency after fixing the system error. Don’t overclock, it’s best not to use software with too much capacity or software that tests CPU overclocking.

Blue screen code 2: 0X0000007E、0X0000008E

Analysis of the cause: Generally, it is caused by viruses, memory damage or poor contact.

Solution: Press F8 to enter safe mode, the system will be disinfected, or you can try to re-plug the memory. Generally, the memory damage probability of this code is not large.

Blue screen code 3: 0X000000D1

Analysis of the cause: Generally it is related to the graphics card, which may be caused by the damage of the graphics card or the installation of a less compatible graphics card driver.

Solution: Try to download a graphics card driver installation on the official website. If it still doesn’t work, the host has an integrated graphics card, try it with an integrated graphics card, or directly unplug the graphics card.

Blue screen code 4:0x0000001A

Analysis of the cause: Some of the brand-name memory modules are heated.

Solution: Change the memory stick to solve.

Step 1: to eliminate hardware failures and memory failures, starting from the memory stick, in the case of ensuring that the memory is not damaged, remove the memory strip and wipe it, then plug it in again to solve;

Step 2: If you are using two memory modules, you can try to unplug one of the memory modules.

Step 3: If it has not been solved, check whether the hard disk is faulty, check if there is a problem with the data cable, and then try to format the hard disk. In addition, if the video card is damaged, it may also cause.

Blue screen code 5:0x0000007B

Cause analysis: Error due to system boot.

Solution: You can try to change the hard disk mode, or go to the PE to repair the system boot.

Step 1: restart the computer, press the shortcut key F1, F2 or Del key after the boot screen appears (different computers enter the bios shortcut keys are not the same, the general boot interface will prompt) enter the bios startup item setting interface, through the keyboard Use the left and right arrow keys to move the cursor to “Advanced”, then press the up/down direction key to select “SATA Configuration” and press the Enter key to confirm.

Step 2: A mode selection window will pop up. Here we use the up and down arrow keys to move the cursor to select the “AHCI” mode, and then press the Enter key to execute.

Step 3: After completing the above two steps, just press F10 to save the changed settings. When the computer restarts and enters the system loading screen again, we will find that the blue screen error code 0x000007B is no longer displayed. Most of the problems with this blue screen are caused by the non-compliance of the hard disk mode in the bios settings with the current system.

Blue screen code 6:0x0000000A

Analysis of the cause: There is a conflict in the computer driver, and there are more problems with the graphics card and the chipset.

Solution: Enter safe mode, delete the latest updates and installed graphics card and motherboard drivers.

Step 1: Return to the desktop interface of your computer, then right-click on the desktop computer icon and select Manage Options from the Sliding menu.

Step 2: In the open computer management interface, click Event Viewer – Manage Event Summary in the left window to determine which driver is the fault. After determining the faulty driver, manually uninstall the driver. That’s it. If it is a computer compatibility problem, we can use the system diagnostic tool to check whether the hardware and driver are compatible with the system, and then re-set its compatibility.

Blue screen code 7:0x00000074

Cause analysis: Indicates that the registry has an error. This error can occur if the system module is corrupted. This error can also occur if some of the registry’s key key values are missing. This may be the result of manually editing the registry.


(1) At startup, press F8 to enter “Enable Debugging” for debugging.

(2) If it is invalid, please backup the data in advance, then press or press F10 at boot time to restore the computer to the factory state by using the system to restore the factory function.

Blue screen code 8:0X000000ED

Analysis of the cause: The fault is mainly related to the hard disk and the system. The probability of system damage is large, and the probability that the hard disk is really bad is relatively small, and there may be a problem with the volume.

Solution: Reinstall the system / replace the hard drive.

The above is a more common computer blue screen solution. In short, the blue screen code is tens of thousands, safe to use the first! If you don’t have any blue screen code above, then please contact our after-sales staff.

How to change the minicomputer desktop path?

The default desktop path of the minicomputer is usually on the C drive, and we especially like to put the files on the desktop, because the desktop is convenient and easy to find. For a long time, more and more desktop files will be available, and the C disk space will become smaller and smaller, which will slow down the system. How to set the system desktop path to a non-C drive? This tutorial will be explained for everyone.

1. Double-click “Computer or this computer” on the desktop

2. Right click on the “Desktop” and select “Properties”

Key points: If you are a Win7 system, please find the user folder on the system disk (C drive), and find the desktop folder under the folder of your own username. The default path is C:\Users\Administrator\Desktop

3. Click on “Location” to change the disk placed on the desktop (I want to place the desktop on the D drive, change C directly to D) and click “Apply”.

4. Click “Yes”

Key points: If you are a Win7 system, please find the user folder on the system disk (C drive), and find the desktop folder under the folder of your own username. The default path is C:\Users\Administrator\Desktop

5. Click “Yes”

6. We smoothly moved all the files on the desktop to the D drive, so that we can safely save the files directly to the desktop.

Key points: In fact, the space in the C drive only affects the running speed of the computer system, because our system is installed in the C drive, but it doesn’t matter if the computer card is not stuck!

Is the mini pc crashed related to C drive capacity?

Is your mini pc always deadlocked? We have already written some articles about “cleaning the C drive and speeding up the mini pc”, but after all, it can’t solve the problem of the mini pc. This issue is mainly to provide a professional answer to the questions that everyone is generally concerned about. It can be said that it is a guide to avoid pits, and we hope to help everyone.

Q: If there are too many files or other things in C Disk, will the system be stuck?

A: Yes! There is a certain relationship between the system card and the remaining capacity of the C drive. We must ensure that the capacity of the C drive is not less than 1G (the XP system must not be lower than 500M). If the capacity is too low, it will be stuck, and even the system will be in a state of paralysis. Because the system needs cache space, this 1G is available. The space requirements, too much does not make sense.

Q: Is the mini pc crash related to the remaining space of the C drive?

A: It doesn’t matter (when the remaining capacity of the C drive is greater than 1G), the mini pc can find the problem from the running speed of the mini pc. This running speed is determined by multiple accessories inside the host. The decisive factors are the CPU (determining the running speed), the memory (determining the mini pc operating system, the smooth running of the program), the graphics card (determining the screen effect and smoothness of the game), and the hard disk (the read and write speed of the hard disk affects the mini pc). The use of fluency), so that if the performance of your mini pc’s main accessories is not strong, even if the capacity allocated by the C drive is large, reinstalling the system every day, cleaning the disk space every day is not helpful, how to card or so card .

Q: How is the SSD partition suitable?

A: SSD partition does not affect the service life and performance of SSDs. When we use a mini pc, it is inevitable that there will be a mini pc crash and poisoning. Separate a drive letter for the system and put important data on other disks. Will result in the loss of data from other disks. The hard disk capacity can be divided into 2-4 zones, and the data is classified for easy management. However, if the hard disk capacity is small (120G or less), one partition will be fine. However, there are a few points that you need to pay attention to. First, don’t divide too many areas. You can divide 2-4 areas according to your needs. You are not allowed to divide too many areas because the more space you waste, the more space you have. Too many partitions will also cause partition misplacement, which will have more impact on the performance of SSDs. Second, if the storage of each partition of the SSD is getting fuller, it will cause its performance to decline. After the small-capacity SSD is divided into too many areas, the partition will be more easily full, and the usage of a certain partition will exceed 90% for a long time. The state of the SSD will cause the SSD to crash more easily and affect the speed of a hard disk, so it is more suitable to divide the two disks.

Q: Which disk is the software installation path suitable for?

A: If your mini pc is a pure solid state drive, you don’t have to worry about the software installed on the C drive affecting the speed of the mini pc. You can install it directly on the C drive. If it is a pure mechanical hard disk, do not install it on the C drive (system disk). If it is a hybrid hard drive (solid state drive + mechanical hard drive), try to install the software on the solid state drive, and the file is stored on the mechanical hard drive. This will greatly improve the smooth running of the software.

Key points:

1. Not the larger the remaining space of the C drive, the faster the mini pc runs faster. As long as the remaining space of the C drive is greater than 1G, the running speed of the mini pc is only related to the mini pc configuration. The remaining space of the C drive is less than 1G, which will affect the system operation.

2. SSDs are not recommended to be divided into too many areas, generally two areas can be, one is the system disk and another disk that stores important information.

3. Path to install the software The mechanical hard disk is recommended to be installed on a non-system disk. The solid state drive can be installed directly under the solid state drive.
