The hard disk light is always on and cannot be started Connecting the hard disk will not successfull

Does your hard drive have a system? Can at least get into boot on other computers? What is the interface between your hard disk and optical drive?

If you doubt the motherboard settings, you can restore the BIOS settings to the factory state, change the boot order, and try to change the device to other interfaces. The following analysis will see if it will be useful to you:

Are your hard drives and optical drives IDE interfaced or something else? Is it possible to connect the motherboard and the optical drive to the same line? This kind of problem usually occurs in the early stage when the IDE interface equipment is connected to the same line without the correct setting of the main and secondary disk jumpers.

Can you only see one hard disk and optical drive in the BIOS after you connect it? If it's the problem I'm talking about, you add an IDE data cable to connect the optical drive and the hard disk to IDE1 and IDE2 respectively, keep the original jumper is no problem, if you have to connect it on a line, you go to check the jumper description of your device, and the correct connection of the jumper is OK (the connection of the jumper must be seen clearly and connected correctly, I have encountered a friend who jumped the hard disk jumper and burned the circuit of the hard disk).

Try changing the interface of the hard disk or optical drive. Then try to reset the motherboard BIOS settings.

From your description, it seems that you have mastered the startup setting operation and handled it correctly, the optical drive light flashed and clicked but could not start the computer, and the same is true for changing the optical drive, eliminating the problem of optical drive, I have also wiped the memory module many times, this process has nothing to do with troubleshooting, I had to start from the hard disk instead, ok, the result is normal, this phenomenon troubleshoots the motherboard possible.

Recently, the startup is not normal, sometimes you have to press the start button several times to start repeatedly, if the boot here says that the optical drive starts, it is recommended that you boot into the BIOS for a few seconds and then exit to see if the optical drive has just been powered on for a long time will cause a failure.

The computer starts up normally, and the optical drive can also be normal after the computer is started** and burning, which also points to the different working conditions when the power is just turned on, and the power supply load is large when it is just powered on, so replace the power supply to test it and eliminate the possibility of power failure.

Now there is only the optical drive interface to the motherboard hard disk interface This section you have not taken measures to check, it is recommended to pull the hard disk cable directly connected to the optical drive to check, the hard disk cable problem will also be affected, and the performance is similar to the decline in the ability of the optical drive to read the disk. If the problem is still there, I can't analyze it.

First, you check whether the optical drive is running normally, put the disc in the normal system to see if it can read the disk normally, and secondly, boot into the BIOS to set the optical drive to boot, if it still can't enter, it means that there is something wrong with your boot disc. Normally, the optical drive is good and readable, which is basically a problem with the settings and the disc.

First of all, please confirm whether the boot item of the BIOS is set to the optical drive as the first activation item, if you confirm that the settings are correct, then there are only two possibilities that will cause the optical drive to fail to boot, one is that the boot disc itself is faulty, the optical drive cannot be read or the data reading is incomplete, and the other is that the optical drive is damaged.

1st boot device is set to cd *** drice is booted from the optical drive first;

1st boot device is set to hard disk drives to boot from the hard disk first;

1st boot device is the first boot device.

The 2nd boot device is the second boot device.

The 3rd boot device is the third boot device.

When powered on, the system will detect the boot device in order according to the settings, when set"1st boot device "for"cd/*** drice"If there is a boot disc in the optical drive, then the system will boot directly from the optical drive; If there is no boot disc in the optical drive at this time, then the system will detect it"2nd boot device"(Second Boot Device), if the second boot device can boot normally, then the system will start the system with the second boot device. And so on.

That is, if yours"1st boot device"Set to"cd/*** drice"Optical drive start,"2nd boot device"Set to"hard disk drives"Hard disk boot. Then when the computer is turned on, the system will first detect the optical drive to see if it can be booted from the disc; If there is no disc in the optical drive at this time, the optical drive fails to boot, the system turns to detect the hard disk, if there is an operating system installed on the hard disk, then the system will start the machine with the second boot device --- the hard disk.

After the disc boots, you can choose to repair the system, which may be caused by the so-called master boot record not existing, and the hard disk partition has boot files, but there is a lack of boot blocks to guide these files.

Leave the optical drive and hard disk unconnected, restore the default settings of the BIOS, save and shut down.

Then connect the hard disk and optical drive, and it is best to change to another data port to see if you can find the hardware and boot normally.

If that doesn't work, try to see if the disc can enter the hard disk after booting, either reset the boot partition of the hard disk, or reinstall the system to try it.

It cannot be judged as a hardware problem until the end.

No Bootable Device Press Any Key - Insert the bootable disk and press any key to continue.

The hard drive may not be properly connected, or the hard drive may be damaged.

Find someone to fix it, it's best to find someone who bought a computer for you to fix it.

1. It may be that the hard disk partition is wrong, and 2. It may be that the data cable is broken.

3. It may be that the hard disk is broken.

Method: 1. Disconnect the hard disk data cable first, 2. Start the computer with the ghost disc, and enter the PE system, 3. Then connect the hard disk data cable, 4. Open the partition software in the PE system, if you can recognize the hard disk, then repartition, it is best to delete all the partitions on the whole disk and repartition.

5. Reinstall the system.

Hard drive jumpers.

If it doesn't work, change the data cable.

The BIOS settings are set to boot from the disc.

Your hard disk cannot be read, and each hardware must be detected when you boot it, and the hard disk cannot be detected, which will only occur.

In the BIOS, the first startup item should be saved as CD *** and restarted, and that's fine.

Most of this situation has something to do with hard drives, and you can try to rule it out in line with the principle of soft before hard

First: Set to boot from the disc first: take out the disc, restart the computer, and see if you can boot from the hard disk.

Second: the hard disk partition table is corrupted or the partition is wrong: after entering the PE, you can run diskgen, view your partition, if there is no error, it is recommended that you delete the first partition, rebuild the first partition, pay attention to remove the files on your desktop and in my documents first.

Third: If you repartition and reinstall the system still can't boot, then there may be a problem with the boot file MBR of the hard disk, you can update the MBR in DiskGen, updating the MBR will not damage any of your files, you can also do this step first, and then do the second step.

Fourth: If it is a desktop, your hard disk cable is broken, it is recommended to replace a data cable.

Fifth: Your hard drive is broken. You have to replace a hard drive.

"It can only boot from the disc and cannot boot from the hard disk normally"Does it mean that when you boot from the hard disk, you will be prompted with a missing file? If so, the system is broken, and the only way to reinstall it is to reinstall it.

It is recommended to check the hard disk for bad sectors, then replace the data cable, change the motherboard socket, and finally check whether the system files are corrupted or lost.

Start from the disc into PE,And then transfer the important files on the desktop,Then reinstall the system.,If it can't be solved,It should be a BIOS problem.,This is not something that ordinary enthusiasts can solve.,It is recommended to take it to the store for repair.。。。 I've had a hard lesson @@@

It's impossible not to see the hard disk boot item in Bois, you must have it if you look for it, obviously you just don't set the hard disk to boot will not boot, you can use the disc to set the first boot device in the advanced BIOS parameter settings to cdrom (optical drive boot).

The second boot device is set to HDD-O (hard disk boot).

third boot device.

First, it may be that the data cable or power cable connected to the hard disk of the motherboard is loose. Second, it may be that the motherboard BIOS has disabled the hard disk for you, and generally restoring the motherboard factory settings can solve the problem. Thirdly, your hard drive is broken...

Other than that, I can't really think of why.

If you can't find the hard drive, you'd better check your hard drive connection cable and plug it back in.

The hard drive should be poisoned, if there is nothing important, format it.
