Different brands, when the boot screen appears, you can press the f function key to select the drive letter to boot, but it depends on your motherboard, or brand. You can consult the dealer, or pay attention to whether there is a line of English prompt under the boot screen, some are one of F1-F12, you can also start a few more times to try the button,

3. Select the default mode for all modes, and click "Start Production";

4. Click "OK" to format the USB flash drive to start making the PE boot disk;

5. After the production is completed, click "No", unplug the USB flash drive and insert it into your computer;

6. Enter the PE menu after starting from the U disk, select or enter, and run the PE system;

7. Double-click [PE One-click Installation] to open the installation tool, select the system ISO path for the image path, and click the drop-down box to select the GHO file;

8. Then click [Restore Partition], select the system installation location, usually C drive, or select according to the volume label and disk size, and click OK;

9. A dialog box pops up, check Restart and Boot Repair after checking, and then click Yes;

10. In this interface, perform the operation of decompressing the system to the C drive, which takes about 5 minutes;

11. After the operation is completed, the computer will automatically restart, and the old peach USB flash drive will be pulled out at this time, and the installation system and configuration process will be automatically executed;

12. The installation process needs to be restarted many times, and the whole installation process takes about 5-10 minutes until the boot enters the new system desktop and the system installation is completed.

The information you provided is useless. Enter the BIOS to set the USB flash drive boot priority, save the reboot and it will automatically boot from the USB flash drive, and then install it according to the prompts. If you can't get it, just hire someone to help you.

In addition, the system USB flash drive you said should be installed in an image, and you need to report the original file to make a backup before making a system, otherwise it will not be fun if the file is lost.

Press the DEL button on boot and select USB flash drive to boot in BIOS settings.

Press the del key on the keyboard, find it by yourself on the top of the up, down, left and right, and press it continuously when you turn it on.

Different brands of motherboards or whole machines correspond to different function buttons. Try pressing the F12 or DELETE key while the machine is turned on.

It depends on what brand of computer you have, but you can try the ESC, Delete, and F12 keys.

If you don't know how to install the system, it is recommended to find someone to help solve the problem.

Generally speaking, press F8 when powering on

However, the shortcuts for the launch options will be different for different brands, such as:Some Dell notebooks are pressed f1Go to Startup Items.

If there is no response after pressing the above shortcut key, it means that the USB flash drive is prohibited from booting in the BIOS settings. At this time, you can press F2 or Del to enter the BIOS, set the USB flash drive boot to a preference in the boot option of the boot menu, save and then restart. After restarting, the computer will first read the system data through the USB flash drive, so as to complete the USB flash drive system.

Note

After installing the system, it is recommended to re-enter the BIOS settings and reset the boot item preferences back to the hard disk, otherwise the system will give priority to reading the USB flash drive after each boot. If there happens to be a system boot or system installer in the USB flash drive, the computer will automatically enter it.

The computer won't turn on, you try to check it by following these steps:

1. The power switch is faulty, when the power switch button cannot be reset in time after pressing the power switch button due to aging, so that the switch is always in the ON state, then there will be a phenomenon that the host starts to start after powering on the power switch, but it will automatically shut down after 4 seconds. The inspection method is to unplug the panel switch connected to the PW ON interface of the motherboard after powering on, and directly use a small screwdriver to short the jumper to observe whether the host still has a 4-second shutdown fault. If the fault disappears, it can be concluded that there is a problem with the switching circuit.

2. The reset switch or jumper is short-circuited.

Although there are few opportunities for such failures, with the increase of computer use time, the non-self-locking button switch used by the reset key will fail to pop up after pressing due to elastic failure, resulting in a state of always on; Or because the button on the front panel of the chassis is not installed in place or deformed, the reset switch button cannot be reset in time after being pressed, and it is in the state of being turned on for a long time; And then because during our maintenance, pulling, unplugging and unplugging inadvertently caused the reset line to short-circuit. At this time, when we press the power switch, because the motherboard is always in the reset state, although the mains power has been turned on, the CPU fan and power supply fan, graphics card fan, motherboard fan have all started to work, but the host computer has no sign of booting. If we have a debug card inserted into the PCI slot, we will immediately notice that the reset light is always on, and we can immediately determine that there is a short circuit in the power supply related to the reset.

3. The memory is faulty.

When a chip or resistance and capacitance of the memory fails, sometimes the host can be powered on after booting, but there is no "beep" sound of normal start-up, and there is no memory alarm sound, and it cannot be started for a long time. Another situation is that if the frequency of the memory or related parameters is set incorrectly when the CMOS is set, there will also be a phenomenon that the power-on host can be powered on, but there is no alarm sound even if it is not started.

Troubleshooting: For this kind of failure, we can unplug the memory first and then boot the computer, if the host memory alarms, it means that the CPU and the host are basically normal. Try to clear the CMOS settings again to see if the fault can be solved, if the troubleshooting indicates that the fault is caused by the wrong setting of memory parameters in CMOS; If that doesn't work, we need to use the substitution method, which can generally troubleshoot the memory fault.

1. First of all, plug the installed U disk into the computer, then turn on the computer to enter the installed system 2, and then click the browse button in the dialog box that appears.

3. Then select the system image file.

4. Next, select the system disk, which is also the C disk.

5. After clicking OK, the system will be automatically reinstalled.

There's a network security mode to get into everything that's easy to do, F8

Volume and power keys are pressed and held by colleagues.

The disk is inserted into the target computer, and the boot boot selects the U disk to start, and there is a prompt under the logo to press the keyboard when the machine is generally booted, each computer is different, and the commonly used keys are posted here.

3.Boot method: Press the boot button after pressing the boot button, my computer is the esc key, and then there will be a selection interface similar to the following, select your U disk.

The last two items here are USB flash drives, and if both appear, the item with UEFI is preferred, and it would be nice if there was only one direct choice. Then press any key until you see the Windows opening ** logo, and follow the prompts to install it.
