Have you ever turned on your PC and found yourself in front of the message “Cannot Find Operating System”? This is a problem that is somewhat frustrated and can occur on any device, both with Windows and with Linux. When a computer cannot find an operating system, it means that there is something that prevents the system.
The cause can multiply: errata BIOS configurationDamaged bootloaders, hard drive are not detected or even hardware errors. Fortunately, in most cases it is possible to solve problems without having to replace components or data loss.
In this detailed guide, we will see all possible solutions to restore the operating system and return the PC function.
Common causes of problems
To solve problems, it is important to understand what can cause it. Here are the most common causes:
- Problems with Bootloader: This is the software that starts the operating system. If damaged or damaged, the computer will not be able to find the operating system.
- Hard drive is not detected: BIOS may not recognize the disk because of the damaged cable or disk failure itself.
- Damaged system file: Poor updates, current disorders or viruses can damage important files from the operating system.
- Problems with BIOS/UEFI: BIOS renewal goes bad or wrong configuration of start orders can prevent the loading of the operating system.
- Hardware error: If a rigid disc has a damaged sector or will stop working, the system may no longer begin.
Now let’s see how to overcome this problem step by step.
Check the BIOS/UEFI settings
BIOS (or UEFI on the latest PC) is the first place to check when the operating system is not found. This is how to access BIOS/UEFI:
- Turn on the computer and repeatedly press one of the following buttons: F2, F12, Del O Esc (depending on the PC manufacturer).
- After you enter the BIOS, find a card Boot O Beginning.
- CheckStart the order And make sure that the disk containing the operating system is the first on the list.
Disable safe boots
If you have installed a new operating system, Boot is safe can prevent the beginning. Try to deactivate it by following these steps:
- I access the BIOS.
- Find the option Boot is safe and set With disability.
- Keep change and out.

If the disk is still invisible, the disk’s physical connection must be verified.
Check the hard drive connection
Rigid disks that are not detected by BIOS can be terminated or have hardware problems.
What to check?
- If you use a fixed PC, open the kasing and make sure the SATA cable is well connected.
- Try to connect the disk to other sata doors.
- If you use SSD NVME, make sure it is put well into the slot.

If the disk does not appear in the BIOS, you might need to test it on another computer to understand if it’s a mistake.
Return the bootloader
If BIOS recognizes the disk, but the system does not begin, the problem can be in the bootloader. To fix Windows Bootloader:
- Create a USB stick with the support of Windows installation.
- Start the PC from the key.
- You choose Return the computer > Solution to problem > Orders.

- Type this command one by one and press delivery after each:
Bootrec /Fixmbr
Bootrec /Fixboot
Bootrec /scanos
Bootrec /RebuildBCD - Start the PC and check whether the problem is solved.
Do the door LinuxYou can recover the GRUB with:
Sudo Grub-Install /Dev /SDX
sudo update-grub
Use the Chkdsk command to correct the disk error
If the hard drive is recognized by the BIOS but the operating system does not begin, there may be an error in the file system. Chkdsk (check disk) This is a Windows tool that can detect and fix this problem. To do CHKDSK:
- Starting PC from Windows Installation Support (USB or DVD).
- Choose Return the computer > Solution to problem > Orders.
- In the command prompt, type:
CHKDSK C: /F /R /X- /F correct disk errors.
- /R. Identify the damaged sector and try to restore it.
- /X Let’s demolish the volume before being scanned.
- Wait for the completion of the operation and restart the PC.

If the command finds and corrects errors, the operating system can function correctly.
Restore system files with SFC and DESC
Sometimes, the problem is caused by corrupt system files. Windows offers two tools to fix it:
1. Perform SFC (System File Check)
- Start the command prompt as an administrator.
- Type the command:
SFC /Scannow - Wait for the check to finish and restart the computer.

2. Eseguire Dism (Service and Placement Image Management)
If SFC cannot fix the problem, use SWST:
DISM /Online /Cleanup-Image /Restorealy

This command improves Windows images, which allows SFC to function correctly.
For new mbr or gpt
If the bootloader is corrupt, it might be necessary to re -create a partition table.
The difference between MBR and GPT
- MBR (Master Boot Record): Older, compatible with the inheritance system, only supports up to 2 TB space.
- GPT (Guid Partition Table): More modern, supports greater records and is needed for UEFI.
How to fix MBR or GPT?
- Open the command prompt from Windows installation support.
- Diga:
Diskpart
Disk list
Select Disk 0 (or the amount of your disk)
clean
MBR conversion (o GPT conversion)
GO OUT - After converting the disk, you must reinstall Windows.

Check RAM for any problem
RAM errors can prevent the loading of the operating system.
How to test RAM by memtest86
- Repatriate MEMTEST86 And that created the initial USB stick.
- Start the PC from the key and leave the test.
- If Memtest86 finds an error, you may need to replace RAM.
