The bios on the laptop does not see the hard one. What to do if the BIOS sees the HDD, but Windows does not

Hard drive not detected in BIOS For many reasons, if you connected the hard disk yourself, you should first check whether you connected the interface cable and the power cable correctly. Let's first take a look at the legacy IDE (Parallel Drive Interface) hard drive interface, but much of what will be said applies to SATA hard drives as well. Friends, if this article does not help you, try or.

From the power supply there are power cables to the motherboard, hard drives, we are interested in the hard drive power cable, it ends with a connector that goes to the connector on the hard drive, similar to a plug, if the connection is incorrect, the hard drive activity indicator on the system unit will be constantly on. It should connect freely, without the use of force. The interface cable for connecting a hard drive has a special key, the photo shows the cable, it is missing one contact, and below the controller from the motherboard it is also missing there, as if broken or in other words, there is a special protrusion on the cable, and on the IDE connector in the motherboard The board has a special slot.

Pay attention to the interface power cable on the left, it has the far right conductor marked in red, which points to the hard drive power connector located on the right, this tells us that everything is connected correctly.

Hard drive not detected in BIOS

Connected correctly and hard drive not detected does not matter.

We are trying to connect our hard drive to another SATA or IDE controller (connector) on the motherboard, replacing the SATA interface cable sometimes also solves the problem, try also using a different power supply cable.
Do not forget that sometimes, due to low power or, you will not be able to detect a second connected hard drive, and problems may also arise with the first one.
If you are using IDE-SATA adapters, try replacing them.
Problems with determining the hard drive in the BIOS may arise due to numerous.
We are trying to load the BIOS settings in the optimal settings. How to do this is our article Load Setup Defaults ..
Know one thing about outdated IDE hard drives, no matter what modern motherboard you have, if the manufacturer left at least one IDE controller on it, and this usually happens, then such a hard drive should work in your system unit.
Next, we look to see if we have the IDE controller itself enabled in the BIOS, pay attention to this Ami BIOS, you may have an Award BIOS, but the meaning is the same.

The wonderful times when no hard drives simply existed have long since sunk into oblivion. The development of high technologies differs from others in that it does not obey general laws, but rushes forward like a stratospheric rocket.

Tape mechanisms may have failed more often than modern magnetic disks, but the reasons for their failures were much more understandable. Although ... what are we talking about! No, we do not call everyone to return to the Stone Age. God forbid! We simply give some comparisons, which, according to certain parameters, do not always turn out to be in favor of modern technology.

So, your hard drive has broken down or you suspect that the breakdown lies precisely in it - in the inadequate operation of this complex and obscure device. You are saved if there is another PC near you that sees its own hard drive. Just swap these two disks and make sure that someone else's machine recognizes it as a working one.

If so, then the problem lies in the wrong settings on your system. If the second computer does not see your ill-fated screw, then it is really faulty, and at least it needs to be repaired. As a maximum, just throw it away and replace it with a new one if its surface did not contain some critical data.

We will assume that the screw was detected by another computer and the essence of the problem must be sought in the settings. It happens that the BIOS (Basic input-output system) does not recognize this or that hardware. In this case, it is usually not recognized by Windows itself. Let's follow this on the example of a hard drive.

BIOS does not see the screw

How to diagnose this problem? Yes, it's very simple: you need to restart the computer while holding down the special keys to enter the BIOS. Depending on the computer model, this can be either the "Del" key or the "F2" key. Although there may be other options: the PC signals them at the start, just look at what it displays on the screen at the time the system boots.

Once in the BIOS, you need to go to the "Integrated Peripherals" section and pay attention to the option called "Onboard IDE Controller". If this option is set to "Disabled", then this means that for one reason or another, the BSVV does not see your screw. Here is an explanatory picture:

Try this:

Carefully check all contacts and connectors, in accordance with the instructions for your "motherboard" and hard drive.
Remove the system clock battery from the connector and keep it disconnected for 10-15 minutes, after which you can insert it again.
Set the "Onboard IDE Controller" option to the correct position, i.e. to "Enabled".

If these manipulations fail to revive the screw, contact a specialist.

The BIOS sees the screw, but the OS does not see it

So, we analyze the situation when the BIOS sees, but Windows does not. It's also a pretty common story. The ability to enter an OS recorded on any of the partitions can be affected by the trite boot order set in the same BIOS.

If the first in turn are faulty or unresponsive devices that are physically present in the system, then the boot process may hang.

In this case, you need to go to the BSVV settings and change the download priorities in a direction convenient for the user.

For example, remove a flash drive from the highest priority devices, from which, in principle, it is impossible to boot if it does not contain an image of a certain OS or contains its “broken” image. Here's what the priority window looks like in practice:

Put the screw in the first place in this list.

Why does the computer not see the hard drive?

I note right away that there are several reasons due to which the hard drive refuses to perform its functions. Such reasons include:

For the first time, a new sata or ide disk was connected;
There were problems with the cable or wires;
Perhaps the BIOS is incorrectly configured or completely out of order;
Weak power supply;
Low cooling system;
The hard drive itself is out of order.

Yes, you need to diagnose, and only then solve the problem. Let's say an inexperienced user will probably have some difficulties with this. Let me help you, and together we will figure out what and how.

The first connection of the hard drive

If this is your first time connecting a screw, then most likely the system simply did not see it. Yes, it is physically in working order, but it is not displayed among local drives.

In order to fix this problem, you need to press Win and R on the keyboard, write compmgmt.msc and select "OK".

Find and select Disk Management.

In the window that appears in the middle, all your connected drives will be identified, including your problem hard drive. As a rule, it is such because of the wrong assigned letter.

Find the desired drive and right-click on it, and then select "Change drive letter or drive path ...".

A window will open in which you will have to click on the "Change" button.

Now select the desired letter and select "OK".

Wrong format

For the normal functioning of the disk in Windows, the NTFS format is required.

Just like in the instructions above, go to "Disk Management", that is, repeat the previous first two steps. After that, right-click on the disk and select "Format".

Select the file system - NTFS, and click OK.

BIOS does not see the hard drive - setting

In some cases, the wrong device priority for booting may be set in the BIOS. When booting the PC, press F2 (or Del). Which key to press will be indicated when the PC starts. By pressing the desired key, you will enter the BIOS.

Please note that due to differences in BIOS versions, the names of menu items hereinafter may differ slightly.

Look for the "Boot" tab. Use arrows to control. Set your HDD to the first place in the list of boot devices (1st Boot Priority/First Boot Device).

Press F10 to save and exit and then press Y to confirm. After that, the PC will boot from the device you set up.

SATA mode of operation

Often, users in the BIOS do not have an operating mode that is compatible with the IDE. In order to make a change, you need to go into BIOS, select Main, Advanced or Integrated Peripherals and find the SATA Operation, Configure SATA As, or OnChip SATA Type setting.

Select IDE or Native IDE, press F10 and type Y.

BIOS does not display hard drive

If the BIOS cannot determine your hard drive, then most likely it is a matter of incorrect settings or their failures.

Incorrect settings appear due to user actions, and failure can occur for various reasons. So, starting from power outages and ending even with infection of the system. This can be indicated by the system date - if it is not accurate, then you have undoubtedly experienced a failure. To fix this problem, you need to reset all settings.

Look for the Clear CMOS jumper on the motherboard.

Change the jumper from contacts 1-2 to 2-3, hold them for 20-30 seconds and then return to their original position. Besides, there is another way. Find the motherboard in the system unit and remove the battery from it.

You will need to return it back in 25-30 minutes.

Conclusion

Now you know what to do if the BIOS does not see the hard drive. I hope you were able to solve your problem, thank you all for your attention, and don't forget to ask any questions in the comments!

Many users quite often encounter a situation where the BIOS cannot detect the hard drive. The BIOS is responsible for the order in which the equipment starts when the computer starts and maintains the health of all computer components. And if the system does not detect installed devices, first of all, we go into the BIOS and check whether they are enabled or not.

The problem can be caused by failures at both the hardware and software levels. When the user turns on the computer and sees the following message when booting up, “DISK BOOT FAILURE. INSERT SYSTEM DISK AND PRESS ENTER. No bootadle device - insert boot disk and press any key", this means that the system did not determine the main hard disk from which the boot starts, or the boot sectors of this device are damaged.

To begin with, let's find out what caused this problem - damage to the hard drive or a malfunction at the software level.

The second case is not so critical, most likely, the damage to the boot sectors was caused by malware or a virus, as a result of which the system did not detect the operating system boot files and issued the above warning.

We go into the BIOS settings, and for this, when starting the computer, use the Delete or F2 keys. The BIOS main menu displays information about all connected hard drives on your computer. If you find a problematic hard drive there, then the problem is most likely caused by a software failure due to corrupt OS boot files.

First, let's test the hard drive for bad sectors. Scanning can be done, for example, using the Victoria program. The fact is that not only viruses can damage system files, but also bad sectors in the boot part of the hard drive. To check the hard drive, we need a boot disk or flash drive with the Victoria program deployed on them. For full diagnostics, you should also add an anti-virus scanner, for example, DR Web LiveDisk or Kaspersky Rescue Disk.

If during the check it turns out that the surface of the drive is not damaged, and malware was detected during the antivirus scan, then it is imperative to reinstall the operating system.
It is highly recommended that you do a full scan of your hard drive for viruses before installing a new OS.

Mechanical damage to the hard drive

If, with the appearance of such a line, you hear noises or tapping of the hard drive, while in BIOS it is displayed in the list of connected devices, malfunctions in this case are associated with mechanical damage to its parts or failure of the controller.

You won’t be able to extract information from a damaged HDD yourself at home, all attempts to fix it even more can aggravate the situation, and you will lose important files forever. To recover data from a damaged hard drive, you should contact a service center.

What to do if the disk is not detected in the BIOS?

If the BIOS does not see the hard drive, then the malfunction is caused by a hardware failure. Let us consider in detail what to do and why this situation may arise.

First, we check the interface cable (IDE, SATA) through which the hard drive is connected to the computer motherboard, as well as the power cable.

Perhaps after cleaning the computer or installing, for example, RAM sticks, you accidentally broke contacts. If everything is in order with the contacts, use a different interface cable and, therefore, a power cable for testing.

The next link with which problems may arise is the motherboard. Checking it is quite simple - you should connect another known working hard drive. Then go into the BIOS and see if it appears. If the BIOS did not detect the hard drive, the motherboard is faulty. Another option is that the IDE or SATA slot on the “motherboard” failed, for example, as a result of a microcrack that appeared due to excessive force when connecting the cable. This is especially true for IDE connectors. In this case, plug the cable into another slot.

Problems when connecting a second hard drive

Pay attention to the IDE hard drive connector, which includes four pairs of pins, located between the cable and power connectors. It is used to set the priority of the hard drive, which is set using a special jumper.

If the hard disk is the main one and the computer is booted from it, put the jumper in the Master position. In case you are adding a second hard drive, make it slave by setting the jumper to Slave. If you did not do this, and two disks are primary, a device conflict will occur, as a result of which the BIOS will not recognize one of them. This situation is typical for hard drives with an IDE interface. To prevent this from happening and you cannot find out the position of the Slave, generally remove the jumper from the second disk.

When you hook up a second IDE hard drive to the same cable as the main one, a situation may also arise when the BIOS does not see it. If this happens, connect it separately to another connector, through a second cable.

Problems connecting a SATA hard drive

First, we check the contacts and the health of the SATA interface cable by replacing it. If everything is in order, go to the BIOS. Here we check the status of ACHI, try to switch it to another mode and see if a problematic SATA hard drive appeared in the list of connected ones. If it does not appear, reset the BIOS settings using the Clear CMOS jumper on the computer motherboard.

When you turn on your computer, the BIOS checks the hardware for functionality. Accordingly, if the hard drive is not visible in BIOS, then the system will not start, since Windows files will not be detected and read. Visually, this error is accompanied by a black screen with a notification that the hard drive was not found.

Possible reasons

If the BIOS does not see the hard drive, then the cause of this phenomenon can be both hardware and software errors in the computer. Consider the main negative factors:

Winchester is disabled in BIOS.
The hard drive is incorrectly connected or damaged.
Jumpers set incorrectly

The described reasons are more related to the HDD, but if you have an SSD drive, then some tips apply equally to it.

Incorrect hard drive connection

If the BIOS does not see the hard drive, then the problem may lie in the incorrect connection of the hard drive to the motherboard. Check that all loops are in good condition, the cables do not have kinks and cuts, suitable ports are used for connection. If a physical property flaw is found (such as a broken cable), it should be repaired, and then try to boot the system again.

The recommended length of the SATA cable is 1 meter. If your cable exceeds this value, then it must be replaced with a shorter one, as this is the reason for incorrect BIOS operation. Be sure to check that all cables are securely connected - sometimes they just fall out of the connectors.

Jumpers problem

If you have two hard drives connected at the same time, and at the same time you are using the IDE interface, then you need to check that the jumpers on the hard drive are set correctly. The jumpers tell which HDD is the master (i.e. Master), and which is the slave (Slave).

Note: If you have two SSD drives connected, then no jumpers are required.

Instructions for the correct installation of jumpers can be found directly on the hard drive case. If there are two disks, then one should be set as " Master", And the second as " Slave". Be careful: some hard drive models work in slave mode without a jumper.

Pay attention to other equipment - if it is connected incorrectly, the BIOS will malfunction, which leads to an error when trying to detect the hard drive. The cause of the problem can also be ordinary overheating: check the cooler and put the entire cooling system in order.

BIOS check

Any hardware connected to the computer is turned on and off through the BIOS. Sometimes a software failure leads to the fact that a change in the operating mode of the device occurs without the knowledge and participation of the user.

To start .
Make sure the SATA connector is set to Auto, that is, it is detected automatically.
Find the "SATA Configuration" option and set it to "Enabled".

If you are afraid to climb the BIOS settings, just try resetting them to the factory state. Remove a small battery from the motherboard or use the Load Optimal Defaults item in the Exit section.

Winchester damaged

If no manipulations with the cables, the hard drive itself and the BIOS bring a positive solution to the problem, then you should think about the state of the hard drive. First, try connecting it to another computer. If the BIOS does not see the hard drive here, then the media is most likely broken. In this case, it is better to think about how to save the information, since the damaged hard drives themselves are usually not recoverable.
