This generally happens due to a hard disk which is not working. It can be due to many reasons:
- SATA data cable which goes from hard disk to motherboard is loose or broken.
- Hard disk failure. This can also cause this error.
- Boot sector viruses. Maybe a boot sector viruse has erased the boot signature code in the boot sector of your windows installation.
- Due to loose power cable which runs from the power supply unit to hard disk.
- Faulty SATA slots on the motherboard.
- Faulty Power supply unit.
- Hard disk corruption.

- SATA data cable which goes from hard disk to motherboard is loose or broken.
- Hard disk failure. This can also cause this error.
- Boot sector viruses. Maybe a boot sector viruse has erased the boot signature code in the boot sector of your windows installation.
- Due to loose power cable which runs from the power supply unit to hard disk.
- Faulty SATA slots on the motherboard.
- Faulty Power supply unit.
- Hard disk corruption.
To repair the problem, the first step should be to check whether all the cables running from the hard disk or the boot device you are using are properly connected. Ensure the power supply cable to your hard disk is not damaged. Also ensure the SATA data cable is not damaged. If no cable is damaged then the problem is either with your Hard disk, motherboard or power supply unit.
Go to BIOS and check whether the BIOS can detect the hard drive or not. Of the BIOS can detect the hard drive then it means that your motherboard and power supply unit is fine but there may be some error with your hard disk. Either it is corrupted or there is some hardware error in the hard disk. Try to reinstall windows. If this works you are fine to go. The corruption may have been caused most probably due to power outage. In this case get your power supply unit checked. If there is no error in the power supply unit of hard drive you are fine to go.
If your BIOS cannot detect the hard disk there is some problem with your hardware. Either hard disk, motherboard or power supply unit. These parts should not be serviced at home. Consult a computer repair technician or your computer hardware manufacturer.
If the above steps don't help troubleshoot the problem, go to a computer repair shop.
I once met a man who drove a modest Toyota Corolla, wore beat-up sneakers, and looked like he’d lived the same way for decades. But what really caught my attention was when he casually mentioned he was retired at 45 with more money than he could ever spend. I couldn’t help but ask, “How did you do it?”
He smiled and said, “The secret to saving money is knowing where to look for the waste—and car insurance is one of the easiest places to start.”
He then walked me through a few strategies that I’d never thought of before. Here’s what I learned:

I once met a man who drove a modest Toyota Corolla, wore beat-up sneakers, and looked like he’d lived the same way for decades. But what really caught my attention was when he casually mentioned he was retired at 45 with more money than he could ever spend. I couldn’t help but ask, “How did you do it?”
He smiled and said, “The secret to saving money is knowing where to look for the waste—and car insurance is one of the easiest places to start.”
He then walked me through a few strategies that I’d never thought of before. Here’s what I learned:
1. Make insurance companies fight for your business
Most people just stick with the same insurer year after year, but that’s what the companies are counting on. This guy used tools like Coverage.com to compare rates every time his policy came up for renewal. It only took him a few minutes, and he said he’d saved hundreds each year by letting insurers compete for his business.
Click here to try Coverage.com and see how much you could save today.
2. Take advantage of safe driver programs
He mentioned that some companies reward good drivers with significant discounts. By signing up for a program that tracked his driving habits for just a month, he qualified for a lower rate. “It’s like a test where you already know the answers,” he joked.
You can find a list of insurance companies offering safe driver discounts here and start saving on your next policy.
3. Bundle your policies
He bundled his auto insurance with his home insurance and saved big. “Most companies will give you a discount if you combine your policies with them. It’s easy money,” he explained. If you haven’t bundled yet, ask your insurer what discounts they offer—or look for new ones that do.
4. Drop coverage you don’t need
He also emphasized reassessing coverage every year. If your car isn’t worth much anymore, it might be time to drop collision or comprehensive coverage. “You shouldn’t be paying more to insure the car than it’s worth,” he said.
5. Look for hidden fees or overpriced add-ons
One of his final tips was to avoid extras like roadside assistance, which can often be purchased elsewhere for less. “It’s those little fees you don’t think about that add up,” he warned.
The Secret? Stop Overpaying
The real “secret” isn’t about cutting corners—it’s about being proactive. Car insurance companies are counting on you to stay complacent, but with tools like Coverage.com and a little effort, you can make sure you’re only paying for what you need—and saving hundreds in the process.
If you’re ready to start saving, take a moment to:
- Compare rates now on Coverage.com
- Check if you qualify for safe driver discounts
- Reevaluate your coverage today
Saving money on auto insurance doesn’t have to be complicated—you just have to know where to look. If you'd like to support my work, feel free to use the links in this post—they help me continue creating valuable content.

Typically this happens when the system drive has failed - so would need to be replaced - though sometimes (but very rarely), the problem is because either the data cable or power cable to the drive has come away or the power to the drive has gone bad.
So you need to check the cables and if they seem okay, you need to replace the drive. And if you are going to do that, I’d strongly suggest using a solid-state drive (SSD), which can make the computer between two and five times faster than before.
Another possibility is that the CR2032 battery needs to be replaced. That battery allows the computer’

Another possibility is that the CR2032 battery needs to be replaced. That battery allows the computer’s Bios to “remember” the hardware settings and if it’s run down, effectively zeros the settings in the Bios, so the computer doesn’t know what device to boot from.
If you aren’t comfortable digging around inside a computer, you’d be much better to get a trusted professional to do the work.
The techie should be able to speedily diagnose the problem at no great cost and then agree with you what steps to take.
There could be two reasons behind this problem:
- Faulty installation of Bootable device
- It could happen when Harddisk stops working or connection issue. Try reinstalling Harddisk and checking if all cables are connected properly.
2. Wrong Configuration
- If you have tried to edit any bios settings and boot settings, this could be because of that. Possible fixes are: Changing EFI boot mode to UEFI from bios or checking if the partitions are active or not from live linux.

It means the computer hardware did not find a disk drive which has an operating system (OS) installed. The OS (Windows is an OS) must be installed on a disk and the disk “found” by the hardware. The hardware which boots the computer is called a Built-in Operating System (BIOS). The BIOS is configured to look for devices which have an OS installed. The first one found is used by the BIOS to boot the computer. When no devices have an OS installed, you get that message.
The fix is easy, either 1) attach a disk which has an OS installed, or 2) install an OS on one of the attached disks, or 3) chang

- Checking the BIOS to make sure that none of the settings were changed to prevent your device from booting.
- Make sure that sata cable that connects the drive to the motherboard is working properly. (Will require using a working cable to make sure the current one works)
- Testing a new hard drive in the system can help to see if the current drive is dead.
- The drive may be popping up but showing no device found. Could require reinstalling the operating system.
You need to elaborate on the question. This error appears when your bios cannot find a disk drive which can be booted from. Bios needs a storage which contains the boot files and also which is formatted in the “bootable” format to boot.
If this has occurred randomly, you may have deleted the files required for booting in the location C:/ . Note that these files can only be accessed when the “Show system files” option is turned on in folder options.
Another probability is that your hard disk is corrupted and the files are no longer readable.

Like I said, you need to elaborate on the question, if you are trying to boot from a USB or a DVD, the file system may not be formatted properly to be bootable. Most bios cannot boot from a USB if you just copied the installation or bootable files to the drive, they have to be made bootable manually by using a suitable software.
Unfortunately, suggesting more probabilities seem futile as I have no idea what you were trying to do before the error popped up.
The error you are seeing may mean one of several (ok — three) things:
- Your boot device (hard drive, solid state drive or M2 drive) has failed
- For some reason, you boot device is no longer in the boot order set in your system BIOS
- There is a non bootable drive if some sort inserted/attached in a higher priority than your usual boot device, and for some reason your system is “stuck" at that non-bootable device and is not attempting to utilize devices further down the list. You might see this behavior on some systems if there is a “halt on failure” setting in BIOS.

Most likely, though, your boot drive has failed…
Replace the hard drive. The hard drive may have died. Along with that, insert a UBB drive with a copy of Windows 10 installer. Or it could be a simpler problem. Go into bios and check if your hard drive is enabled in the boot tab
Quick Diagnosis: Open up the back panel of laptop, try disconnecting and reconnecting the RAM and Hard Disk from the motherboard. This will work if you haven’t done anything abnormal with your last time good configuration or working OS.
Normally the operating system is in the hard disk of your laptop. If you are getting this error, it means either your hard disk has crashed or the wire connection between hard disk and the motherboard has become loose.
You could start by checking the connection, if you can do so yourself.
Also to check if your hard disk is ok or not, you can make a bootable USB of ubuntu os and boot from it without installing it. When you are booted in ubuntu, you can go to file manager and check the files on your hard drive. If you can access them, it means your hard drive is working. Then it most probably is a

On the other hand, you'll have to replace the hard drive and install windows again if your hard drive has crashed.
If you can access the BIOS, check for which devices are scheduled to be accessed on startup, and in what order. Alternatively, on startup, tap the F10 or F12 key (depending on maker) to make a manual selection of the startup device, first example: HDD, FDD, DVD, USB. Happy Trails Pilgrim.
You should check the BIOS settings to ensure the boot sequence is set to the correct drive where Windows is installed, and make sure that UEFI mode is enabled if your system supports it. If the issue persists, you may need to reinstall Windows while ensuring the correct boot mode is selected.
Have the same “Error” once in a while. Solution? Check if any USB Memory stick is attached to Your machine. Sometimes I copied some data to my USB Stick and just forgot to remove it prior to starting my machine. No bootable device found is the next thing I see.
If you can access BIOS, try changing boot order and booting from USB( burn a windows iso or a Linux live CD to the USB). If you are able to boot from that, then most probably an OS is not installed on your HD (or) there is something wrong with your HD (or) the OS installation is corrupt.
Bob Crabtree pretty much nailed it.
I’ll just add that you can remove the drive and use a USB adapter to try and read it on a different PC. (Usually it’s a SATA to USB adapter these days, though you should search for your drive type based on your model PC. Costs about $10.00.) If the drive is readable, then it could be the connection on the original PC or the PC could just be bad.
If it’s an old PC, I’d get a new one.
Cleaning deletes all partitions, so you will have to use a live CD with Windows or Linux and run testdisk on it so that it tries to recover your partitions and rebuild the partition table.
If you are using Windows, and you have got the Windows installation media, put in in an optical drive or USB port, as appropriate, and boot up from that. Run a diagnostic to see if Windows can find the problem. Failing that, you might have to reinstall the operating system, or call in an engineer.
Maybe you need to fix the MBR, by starting from a bootable pendrive, or you install from a pendrive a grub2 (you´ll find it researching about dualboot). Both should work. but if you are unlucky, you have a harddisk with a destroyed bootsector. then only a miracle can save you. you will need a new hd.
Try to start the PC using a startup device, i.e a usb stick that is prepared for this purpose or a cd/dvd rom. This boot device missing is caused by misconfiguration or simply the boot device is disconnected or broken.
Disconnect SATA cable from mother board take hair dryer and clean cable and mother board reconnect this should do it if nothing happens buy a new SATA cable!
Run windows disk to try and fix. If it cannot be fixed through windows disc repair feature try to restore from a restore point using that option in windows disc tools. Your boot record or an integral boot file may be messed up.
Quick guess for an old pc the hard drive has died; stick an S.S.D. in there with a fresh instal of windows . You will be surprised by the snappy new performance.
Check you can boot from a USB boot stick - google how to do this
boot from bootable Linux and drag your user data to a backup
boot from windows install media and try a repair install
that may fail- if it does do a full fresh windows install
if that fails try resetting bios to factory defaults and or replacing the hard drive
Just enter your bios and make sure the correct hard drive is the one it’s trying to boot from because if no changed had been made by you then it’s likely your cmos battery is going dead or your hard drive is dead.
make sure you have no external bootable USB devices connected when you boot.
if you value your data and dont know how to retrieve it, take the laptop to a repair expert..
this could be that the drive has died or that the op system had become corrupted - The simplest thing to do would be to fit a new drive and install a clean op system onto it - then to see if anything could be recovered from the old drive
I also faced the issue. As far as I remember, you can put in a bootable pendrive of Windows 10 and juat repair your system image using cmd from the bootable pendrive. Try googling jt.
Another reason you might see this error is: you have a USB drive connected with just regular, everyday files on it & the computer is trying to boot from it. If that is the case, try removing it to see if the computer will start normally =)

I understand this can be quiet a nasty experience when one fine morning you turn on your PC and find that Windows is mysteriously missing. But fret not I will try to help. I will list 4 methods using which you may be able to repair and get Windows 10 up and running. This method is not restricted to Windows 10 only and can be caused in other versions as well.
Method 1: Try fixing by running automatic startup troubleshooter in Windows 10 if this does not solve move on to next solution
Method 2: Probably your boot records are corrupted or Boot Configuration Data (BCD) is corrupt. Now these are the two files that are used while booting into the OS and when they are corrupt then there is no way Windows can boot into. To fix this boot into Windows using your external boot device USB/DVD as the case maybe. When you encounter the screen with install windows, choose Repair your Computer option.
Next choose Troubleshoot,
Select Advanced Options and from there choose Command Prompt.
In the Command Prompt window type the following commands and press enter after entering each command. Note you need to leave a space after bootrec.exe.
bootrec.exe /fixmbr (This command fixes corrupt master boot record)
bootrec.exe /fixboot (This command fixes corrupt boot start up file)
bootrec.exe /rebuildbcd (This command rebuilds Boot Configuration Data a new)
Reboot your PC and check for the problem. If not try Method 3.
Method 3: This can also occur if you have UEFI bios and configured it to boot in legacy mode with secure boot enabled. UEFI is a new version of traditional BIOS and uses GPT Partitions to install the OS. Windows 10 has conflict with this system. To correct this boot into your BIOS.
Restart your PC and press F2 or Del or F12 as the case may be. Check your motherboard or PC manual on how to boot into BIOS.
Then check for security tab or refer your manual and change your Boot mode from Legacy to UEFI.
Or else go to security tab and disable the Secure Boot option. Save the changes and reboot. Check to see if the problem is resolved. Else move on to...
“No bootable device” indicates that whatever media your system is looking to for start up files is missing or corrupt.
First, make sure that the system is set to address the boot media appropriately: if the media (usually your hard drive, SSD or M2 drive) was configured to use “AHCI” boot but has been somehow switched to “RAID”, your system will not boot.
Check to make sure that no=non-bootable media is inserted into your optical drive, USB port or any other location in your boot list
Make sure that there is a “Windows Boot Manager” entry (or at least your hard drive) shown in your Boot Device ta

If all the above have been checked out and are in order, then your boot record and/or MFT have been damaged. There are ways to address this, but they’re beyonf the scope or a Quora answer - seek professional assistance…
When booting up the computer, if the BIOS (basic input/out system) fails to find an operating system, error messages: Operating system not found error occurs or error like:
- Missing Operating System
- Setup did not find any hard drives installed on your computer.
The message is shown in the black windows and prevents me from accessing the desktop.
Therefore, the situation is scary and quite complicated. However, just like many other Windows errors, this one can be fixed.
Below are the main reasons why Windows operating systems are missing.

Therefore, the situation is scary and quite complicated. However, just like many other Windows errors, this one can be fixed.
Below are the main reasons why Windows operating systems are missing.
1. The computer input/output system (BIOS) does not detect the hard disk drive.
2. The hard disk is damaged or corrupted.
3. The Master Boot Record (MBR) on the hard drive is broken. Note that some third-party programs or disk operations can damage an MBR.
4. An incompatible partition is marked as Active.
5. A partition that contains the MBR is no longer active.
There are a couple of ways you can fix Operating System Not Found errors on Windows.
Test Hard Drive Problems:
There is a Hard Disk Self Test in the BIOS to verify the integrity of the hard drive. Users often use this test for regular maintenance of the system.
To perform the test, follow the steps below:
Step 1: Enter BIOS mode by following the instructions for your system specifically. Get to the Diagnostics tab and select the Primary Hard Drive Self Test option.
Step 2: Press the Enter key to run the test, and you can perform a quick and comprehensive inspection. The system will give a detailed status of the test.
In the result, you can see if any of your hard drive components are failing and get it fixed immediately.
Reset the BIOS:
If the hard drive is working fine, then the next thing to do is checking the BIOS settings and making sure that they are correct. Incorrect settings of BIOS can result in the Operating system not finding error. Thus, we need to reset the settings to default to get rid of this error.
Step 1: Remove all the external drives connected to your system and open the BIOS setup. In the BIOS windows, you’ll see the Exit tab.
Step 2: Select the Exit tab and enable the “Load Optimal Defaults” option. The option can be load optimized defaults, Load setup defaults, or get default values depending on the system you own.
Step 3: Once the settings load successfully, select the Save Changes and Exit option, and the BIOS will be reset to the default configurations.
While using this method, make sure that you follow the right steps for your system.
Repair MBR with the installation CD/DVD:
Wrong operations and viruses can damage MBR and cause the Operating System not Found error. As the Windows OS doesn’t boot, you’ll be stuck unless you repair the MBR. If you already have a Windows Installation Disk, then follow the steps below:
Step 1: Insert the disc and enter Boot mode. Get to the Windows Setup menu and start the Recovery process in Command Prompt.
Step 2: Enter C:\> and type “bootrec/ fixmbr” and hit Enter. Press Y for yes and hit enter again when you get the prompt to write a new MBR.
When the writing process finishes, restart your PC and see if the problem is fixed or not.
Hopefully, one of these solutions will work for you. If all else fails, try taking your computer to a dedicated computer repair shop.
Mmm… that is really bad. If you have to ask this question, the best thing you could do, if the information on that laptop matters to you, is to take it to someone who knows what to do (like a computer repair shop).
