The solution to the hard disk cannot be detected by the boot BIOS, method 1, 1Check if the hard drive is damaged. Generally, the hard disk may be damaged for a long time, or it may cause hardware problems due to computer crashes and other reasons, which need to be judged or checked by yourself.

Method 2, 1Go to the BIOS, and in the BIOS options we change the boot mode to the correct UEFI or Legacy boot. It depends on which type of hard disk partition you use, press F10 to save the settings after setting it to check whether it is displayed;

2.In the BIOS we also have to check if the hard disk option is disabled, in this way we can restore the default settings of the current BIOS by pressing a shortcut such as F5 directly, so that the hard disk is not disabled in general.

Method 3.1If you can't find the hard disk to boot, you can do this;

2.First, restart the computer, and press the "Delete" button continuously when the boot screen appears (different computer shortcuts are different) to enter the BIOS interface;

4.After entering the "stat configuration" item, find "sata mode" and tap enter;

5.After hitting enter, the "SATA mode" box pops up and selects "ahci mode" or "IDE mode".

Summary. The system files have been altered so that the computer will not boot, or the hard disk will malfunction.

The computer boot screen is like this, what should I do if I boot up like this?

Hello, it is a pleasure to serve you. What doubts do you have?

This is what my computer turns on.

I need to boot up and send files.

Please wait a moment.

Are you alright?

Hello, this is the boot page.

Right. Don't panic, it's being done in the background.

The system files have been altered so that the computer will not boot, or the hard disk will malfunction.

You can check the hard drive under it.

Good. Haha, it's my pleasure to serve you<>

No display on boot is also a common problem. In fact, you don't need to take the computer to the repair station to spend money on repair, and some small problems can be solved by yourself.

Check 1, first check whether it is a hardware problem, you can observe through the keyboard, when the keyboard is turned on, press the numlock key if the light is on, press once to light it up, it means that there is no problem with the host.

2. If there is no display after the above steps are done, it means that the problem is the fault of the display, and check whether the power cord of the display is powered on.

3. The monitor is powered on, and it is still not displayed, and then check whether the computer monitor cable is loose, please plug it in and unplug it again (the white plug in the picture below is connected to the monitor cable).

4. Finally, if the problem is still not solved, try to replace the monitor cable (generally speaking, the monitor cable is not easy to break).

No display caused by memory failure.

1. If you find that the keyboard does not respond to the check keyboard during the inspection steps, it can be sure that the hardware is faulty, and the highest failure rate in the hardware is the memory. The next step is to disassemble the chassis and use a screwdriver to unscrew the screws behind the main unit.

2. Remove the left cover of the host, and after opening it, you can find that the memory is found on the motherboard.

3. Disassemble the memory, and the card of the memory module can be removed by opening it to the 2nd side when disassembling.

4. Use an eraser to wipe the gold fingers on the front and back of the memory. Due to the long-term operation of the host, a lot of dust will be contaminated with the memory module, resulting in poor contact.

5. Plug in the memory module, then connect all the cables, and start running. It is recoverable.

Most of them are problems with the graphics card.

Discrete graphics card or built-in graphics card.

In fact, there are many reasons why it can't be turned on, such as no power and memory sticks, which need to be checked one by one, if there are no problems, you need to take it to the repair shop to check.

If you want to clear the master boot record, you'd better find a computer repairer, right? Press the "Exit" button "Is it useful?"

2. Hard disk and optical drive reason: boot self-test will also detect hard disk and optical drive, you need to unplug the power cable and data cable of the hard disk and optical drive, and then restart, Xun Xunling to see whether it has passed the self-test, if it can pass, and then further eliminate the problem of hard disk or optical drive.

3. If the above operations are invalid, then it is possible that the hardware is faulty, it is recommended to contact the official after-sales service center and the engineer will help check and deal with it.

According to the fault phenomenon you described, it should be the logo screen fixing, this kind of problem is generally caused by the hard disk, and a small part is caused by the optical drive.

It is recommended that you unplug the data cable of the hard disk and the optical drive first, and see if you can enter the BIOS after booting it, if you can't enter the BIOS after unplugging, that is the problem of the motherboard, if you can enter the BIOS, then plug in the data cables of the hard disk and the optical drive one by one, do not plug in at the same time, through the elimination method, it is the problem of that device.

There should be something wrong with the system, reinstall it!
