Our computer is a complex electronic element that is not exempt from possible failures. An error that can occur to us when we start our computer with Windows 10 is that the following message appears “ERROR: The boot disk has not been detected or the disk has failed.” Today we are going to see why this error occurs, as well as the steps we can take to solve this problem.
Why does this error occur at startup
This error usually occurs when during the boot process of our computer, the system is in charge of checking the hard disk in search of the information necessary to be able to start it, as well as other information such as the operating system it uses. In the event that the computer cannot retrieve the boot information or detect the operating system, the error will appear on the screen.
Of course, everything related to both our disk drives and the PC startup are somewhat delicate and sensitive issues. With this, what we want to tell you is that a serious error in these terms, on the one hand, can prevent access to everything that we have stored on the computer. What’s more, we can even be at risk of losing it, so we must be very careful. The problem here is that, at this point, these types of errors can be caused by a multitude of reasons. That is the first thing we should be more or less clear about, what is the fault that we find on the screen due to.
Some of the causes for which the recovery of the boot information may have failed can be very varied, something that we will talk about below:
- Incorrect boot order setting.
- There is no operating system on the hard drive.
- Hard drive is crashed or broken.
- Any loose connection on the computer’s hard drive.
- Corrupt Boot Configuration Data (BCD)
Steps to fix the fault
In case we start the computer and we get the error message “The boot disk has not been detected or the disk has failed”, we will have to face it, so we will tell you some steps that can help you solve this problem. And it is that as usual, before we get to work to solve the problem, we will have to be very clear about what it is due to.
Therefore, below we are going to show you some of the checks and solutions that you can use in this regard to fix the boot failure we are talking about.
Check and verify the hard drive connections
A common problem that may have occurred is that, due to some sudden movement or blow, the cables that connect our hard drive to the system have come loose, which could cause the appearance of the error when trying to start the computer, since the boot system it would be unable to detect the hard drive. Therefore, before getting fully into the software section, let’s see if the failure is caused by the hardware component most affected here, the hard drives.
To try to solve it we will have to open the case of our computer and in case it is a laptop we will remove the battery. Later we will disconnect all the hard drives and clean all the ports and cables that connect it to the system. Once finished, we reconnect them so that they are tight, connect the battery if necessary, close the lid and turn on the computer to check if it starts correctly. If we prefer not to risk playing inside our computer, we will need the help of a technician. Not all of us are prepared to use or manipulate the internal components that are part of our PC, especially if we have never done so.
The hard drive is crashed or broken
Another reason why the error message may appear when trying to start the computer is due to a hard disk failure. To check this, we should disconnect the hard drive from our computer and connect it to another PC to see if we can access its content. In case it is not possible, we will know that the hard disk is damaged so it will be necessary to replace it.
In addition, if necessary and if the economy allows it, there is no harm that does not come. With this, what we want to tell you is that after changing the main disk drive, we can buy a larger one, or install an SSD if the PC supports it, for example.
Boots with a bootable drive with antivirus
In addition to the errors caused directly by the disk that we have on the computer as such, the problems can be caused by external agents. This is actually what we refer to is the possibility that we have suffered an attack without our realizing it. And it is that they are increasingly powerful and dangerous, so they could directly and catastrophically affect our disk drives or their startup.
That is why we always have the possibility of using a security solution that we have the possibility of copying to a self-racking USB memory. In this way, the operating system itself would initially start from it, so that the antivirus can scan the rest of the disk drives. These programs are capable of detecting some type of malware that prevents the PC from detecting the main unit. Therefore, if it is properly updated, you could remove it so that you can start working normally again.
Check the priority of the boot disk in the BIOS
The error message “The boot disk has not been detected or the disk has failed” can also be due to the fact that our computer is trying to start from a different source and is not able to find the boot system. To do this, we must make sure that the hard disk is at the top of the boot disk in the BIOS. In this case, we must access it to verify it.
To access the BIOS it is necessary to turn on the computer and press and hold the access key, which varies from computer to computer, but usually coincides with the F2 or Delete key. Now we must access Boot Order and locate the boot order. In case our hard drive is not at the top, we must select it and move it with the cursors until it is at the top as the first boot option. Later we save all the data and exit the BIOS. Once we have exited, the computer will restart and it should be able to boot correctly.
Repair or reinstall Windows 10
An easy way to repair this failure can be to use the Repair option found on the Windows 10 installation disc.
Once we start the computer with the Windows 10 DVD, we must select our language and select the “Repair” option found in the lower left. On the next screen we will click on “Troubleshoot”, then on “Advanced Options” and finally on “Startup Repair”. Once the operation is finished, the computer will restart. In fact, it is worth mentioning that in this same starting method we find some other very interesting solutions. Many of them will be of great help to us when we encounter bugs of the severity of this on our PC.
In case that does not solve the problem, try with the same installation disk to format the unit and reinstall Windows 10 or go to the next tip.
Run CHKDSK, command to repair disks in Windows
If the option to repair the system did not work and you do not want to lose all data by formatting and reinstalling Windows 10, you can choose to run the CHKDSK command from the Windows 10 DVD drive.
In this way we will start the computer again with the Windows 10 DVD drive, and once the language is selected we will click on “Repair the computer”. Next, click on “Troubleshoot”, then on “Advanced Options” and finally on “Command Prompt”. Here we must write ” CHKDSK C: / F ” (without using quotes). Later we write ” CHKDSK C: / R ” (again without the quotes) and press Enter. After finishing the CHKDSK process, we will proceed to restart the computer and check if it has solved the problem.
