1. Check the BIOS
You need to check for two things in the BIOS. Firstly, you need to ensure your machine recognizes your hard drive. Secondly, you need to make sure the drive on which you installed Windows is listed as the preferred boot drive.
The methodology for entering the BIOSHow to Enter and Reset the BIOS to Default Settings on Any ComputerHow to Enter and Reset the BIOS to Default Settings on Any ComputerIf your computer won't boot, the BIOS may be to blame. Here's how to enter it and reset it to the factory defaults to fix those problems.Read More changes from manufacturer to manufacturer. Typically, you’ll need to press Escape, Delete, or one of the Function keys. You should see an onscreen message advising you which is the correct key.
The BIOS menuThe BIOS Explained: Boot Order, Video Memory, Saving, Resets & Optimum DefaultsThe BIOS Explained: Boot Order, Video Memory, Saving, Resets & Optimum DefaultsYour computer’s BIOS (basic input/output system) is the low-level software that starts when you boot your computer. It performs a POST (power-on self test), initializes your computer’s hardware, and passes control over to the boot..Read More itself also varies between devices. Broadly speaking, you need to locate the Boot tab along the top of the screen. (You can only use your keyboard to navigate the BIOS menu.)
Within the Boot tab, highlight Hard Drive and press Enter. Do you see the name of your hard drive? If so, keep reading.
Next make sure Hard Drive is listed above USB Storage, CDDVDBD-ROM, Removable Devices, and Network Boot. You can adjust the order using the + and – keys.
If everything in your BIOS menu looked fine, jump to step three. If you didn’t see the hard drive listed, go to step two.
2. Reset the BIOS
If your machine is not recognizing your hard drive, there are lots of possible causes. For non-tech-savvy users, the only easy solution is to try resetting the entire BIOS menu to its default values.
At the bottom of the BIOS menu, you should see a key for Setup Defaults or Reset BIOS. On my machine it’s F9, but it might be different on yours.
Confirm your decision when prompted and restart your machine.
If the operating system is still not found, you can stop reading this article. Unless you know a lot about building computers, you’ll need to take your machine to a computer repair shop.
3. Fix the Boot Records
Windows primarily relies on three records to boot your machine. They are the Master Boot Record (MBR), DOS Boot Record (DBR), and the Boot Configuration Database (BCD).
If any of the three records becomes damaged or corrupted, there’s a high chance you’ll encounter the “Operating system not found” message.
Searching For Windows Installations Hangs
Thankfully, fixing these records is not as complicated as you might think. You just need a removable Windows installation drive. Use Microsoft’sMedia Creation Tool to create Windows 10 installation mediaHow to Create Windows 10 Installation MediaHow to Create Windows 10 Installation MediaRegardless of how you arrived at Windows 10, there's a way to create your own installation media. Sooner or later you might need it. Let us show you how to be prepared.Read More.
When your tool is ready, you need to use it to boot your machine. Depending on your device, you might only need to press a single key during the boot process, or you might have to change the boot order in the BIOS menu.
Eventually, you will see the Windows Setup screen. Enter your preferred language, keyboard, and time format, and click Next. On the next screen, select Repair your computer in the bottom left-hand corner.
Next, navigate to Troubleshoot > Advanced Options > Command Prompt. When Command Prompt loads, type the following three commands. Press Enter after each of them:
- bootrec.exe /fixmbr
- bootrec.exe /fixboot
- bootrec.exe /rebuildbcd
Each command might take several minutes to complete. Once all the processes are finished, restart your PC and see if it boots successfully.
4. Enable or Disable UEFI Secure Boot
Almost every Windows machine is shipped with UEFI firmware and Secure Boot enabledHow to Check If Your PC Uses UEFI or BIOS FirmwareHow to Check If Your PC Uses UEFI or BIOS FirmwareSometimes when troubleshooting, you'll need to know whether your PC uses UEFI or BIOS. Here's how you can check with ease.Read More. However, in some cases it might not work.
For example, if Windows is installed on a GUID Partition Table, it can only boot in UEFI mode. Conversely, if Windows 10 is running on an MBR disk, it cannot boot in UEFI mode.
As such, it’s prudent to either enable or disable UEFI Secure Boot and see if it makes a difference.
You make the adjustments in the BIOS menu. Usually, the option will be called Secure Boot and can be found in the Security tab.
5. Activate the Windows Partition
It’s possible that the partition which Windows is installed on has become disabled. You can fix it using Windows’ native diskpart tool.
To work through the following steps, you will once again need a Windows installation media USB.
Turn on your machine and boot from the tool. As in step three, you’ll need to enter your language preferences, etc. then click Next, then select Repair your computer. Go to Troubleshoot > Advanced Options > Command Prompt.
In Command Prompt, type diskpart and press Enter, then type list disk and press Enter. You will see a list of all the disks attached to your machine. Make a note of the disk number you need. Typically, it’s the largest one.
Next, type select disk [number], replacing [number] with the aforementioned number. Press Enter.
Now type list volume and press Enter. It will show you all the partitions on the disk you selected. Establish which partition Windows is installed on and make a note of the number, then type select volume [number], again replacing [number] with the number you just noted.
Finally, type active and press Enter.
To see if the process was successful, restart your machine.
6. Use Easy Recovery Essentials
Easy Recovery Essentials is a third-party app that specializes in fixing boot issues. If none of the previous five steps have worked, it’s worth trying.
In addition to fixing the “Operating system not found” message, it can also solve other common startup error messages.

I leave my Vaio laptop running 24/7. The other day I woke up to the dreaded 'Operating System Not Found' error message (or I'd like to call Black Screen of Death). This article didn't help me because I can't even access the BIOS screen (it uses UEFI) -- upon turning on the laptop it instantly shows the error.
If you have used Easeus Partition master as I did unfortunately, try Macrium Reflect free edition. Macrium worked miracles for me. maybe you. It took about three hours to clone my 200Gb hdd to ssd. and only the windows partition since my original drive was larger.

Then I entered password from this site bios_PW.org.

How to fix it?Ten Days ago with my ASUS Windows 10 Laptop I got an even scarier error.
Instead of going into windows it told me: 'autochk program not found - skipping AUTOCHECK'
After that it went to the troubleshoot section and did the same you told to do (rebuild the partition) to no avail.With the neccescary tools at hand I looked on the harddisk. Everything was there - just didn´t boot.
I looked for the error message at google - only 8(!) findings which were not helpfull at all.
So I gave the machine a new Windows OS (with my personal data NOT destroyed) which worked flawless.
Before and after I tested for virus or similar things. No such thing.
I´m still puzzeld what happended to my laptop.
I had to fix a laptop with a similar, but even worse situation - I received a laptop that I helped fixing, which had the contents of the system disk simply 'vanish' (the drive showed up as unformatted). After a BSOD the system wouldn't boot, obviously - because there were no longer any bootable devices present. Why it happened is still a mystery and the laptop owner swears they were only writing up a college paper and I lean to believe they aren't actively dabbling with *free* software (aka 'cracked' ones from downloaded torrents), which makes it even more mysterious. I restored the data from a backup and returned it to the puzzled owner. My wild guess is that it was a result of some virus as well, perhaps a cryptovirus and the antivirus software stopped it before it could encrypt and permanently destroy data.
I tried to use Easy Recovery Essentials about 2 weeks ago - it wouldn’t even run on my Ryzen CPUMSI MB. Email support only and was not particularly helpful. I finally did an image restore and working with PayPal to get a refund
After a device is attached, Windows attempts to locate a matching driver package from which it can install a driver for the device. Windows searches for driver packages from various locations and performs this search in two phases, as described in the following table.
| Search phase | Windows 7 | Windows 8 and later versions of Windows |
|---|---|---|
| Before a driver is installed | DevicePath Windows Update | Driver store |
| After initial driver is selected | Not applicable | DevicePath Windows Update |
Searching for driver packages
After a device is attached, Windows first attempts to locate and install a driver in a trusted system context without user interaction, as follows:
The best matching driver that already exists in the driver store is first installed onto the device, allowing the device to begin operation quickly. In parallel and in a different process, the following will happen:
Windows automatically downloads matching driver packages from Windows Update. If a matching driver package is found, Windows downloads the package and stages it to the driver store. In Windows 10 version 1709 and greater, Windows offers the best ranked driver, which is not necessarily the most recent. Driver ranking considers HWID, date/version, and critical/automatic/optional category. Windows ranks critical or automatic drivers highest. If a matching driver is not found, WU looks next for optional drivers. As a result, an older critical driver of otherwise equal rank takes precedence over a newer optional driver. In Windows versions earlier than 1709, Windows offers critical and optional updates with equal precedence.
Windows also searches for driver packages that were preloaded in the locations that are specified by the DevicePath registry value. This value is under the following subkey of the registry.
By default, the DevicePath value specifies the %SystemRoot%INF directory.
If a better matching driver package than was initially installed is found either on Windows Update or in a location that is specified by the DevicePath value, Windows first stages the driver package to the driver store before the driver is installed. In this way, Windows always installs drivers from the driver store.
