Do you face no operating system found error while trying to reboot your computer? We know that it is terrible. But, you need to stay calm. We have 5 methods for you to fix the issue. We will discuss the solutions in this post.
4 Methods to Fix Operating System Not Found Error
Method 1: Repair MBR or Boot Sector
The BIOS system will check on the startup disk and read the MBR or Master Boot Record when your computer is starting from a bootable hard drive. The MBR will find the active and primary partition on the hard disk – this is where the operating system is.
But, if the MBR fails to locate the boot sector of the system partition, you will not be able to start the computer. Instead, you will see the operating system not found error. To solve this issue, you can repair MBR or Boot Sector. We suggest you use the “Rebuild MBR”, a great feature of Minitool Partition Wizard Bootable CD.
Method 2: Check if BIOS detects the Hard Drive
The common cause of no operating system found error is the hard drive malfunction. When the BIOS system fails to recognize the hard drive, you will get this problem. Therefore, you can check on the BIOS if the hard drive is detected properly.
Reboot your PC and enter the BIOS system. Each manufacture has different BIOS interface, but it is still easy to find the menu that can show you the information of the hard disk. Usually, it is located in the Advanced BIOS Features. Check the first and second boot.
If BIOS is able to recognize the hard disk, then you’d probably need to check the cable.
Method 3: Change the Boot Order in BIOS
Say that your BIOS is able to detect the Hard Disk properly. But, the no operating system found error persists. Here, you can check on the disk boot. Make sure that the first boot is the drive that has the Windows Operating System within. If it is not, you can change the sequence. Then, exit from BIOS. Restart your PC and check if the problem has resolved.
Method 4: Reinstall Operating System
This is probably the ultimate solution for no operating system found error on Windows. Try to reinstall the Operating System on your computer. As long as your hard drive is fine, you can always to this.
Once you have reinstalled the operating system, the Windows is refreshed and you will no longer see the same problem again.
