Error "Error 1962: NO Operating System Found" on Lenovo - how to fix

One of the typical problem when loading a branded PC, a laptop or monoblock Lenovo is an error 1962 with the message "No Operating System Found. Boot Sequence Will Automatically Repeat. In fact, the error is general and for computers of other stamps, but only these code and wording are used on Lenovo, and therefore the user cannot always find a solution to the problem (on other computers it is more often reported: Boot Failure and An Operating System Wasn't Found, Reboot AND SELECT PROPER BOOT DEVICE).

In this instruction detailed about the causes of the 1962 error on monoblocks, computers and laptops Lenovo and about simple (subject to the service life) methods to correct and return the standard download of Windows 10, 8.1 or Windows 7 on the device.

What is the error 1962 No Operating System Found and what is its causes

When you turn on the computer or Lenovo laptop, it checks the boot options recorded in the BIOS / UEFI, and tries to start loading the operating system, for example, Windows 10. In case you can find the appropriate operating system when the download mode is set. The system, you get a message about ERROR 1962 "No Operating System Found" or, in Russian, "Operating system has not found."

Note: The following possible causes of the appearance of an error 1962 do not take into account the option with an empty formatted disk without the operating system, for it such a message will be natural and everything that is required is to install the necessary OS.

Possible causes of such an error:

• Incorrect download parameters to BIOS as a result of your own settings, and sometimes simple reset them, for example, due to the seal battery on the motherboard or static discharges.
• Changing the configuration of drives (connecting new hard drives, SSD, sometimes - USB flash drives) without making changes to the download configuration in the BIOS.
• Damage to the system bootloader, file system on HDD or SSD. It can occur due to its own interventions (for example, attempts to divide the disk to sections excluding important nuances), and sometimes due to external circumstances (sudden power off and others).
• Hardware problems: Damage to the hard disk or SSD, poor contact of the drive connection to the motherboard, damaged SATA cables.

Accordingly, before proceeding with the correction actions, I recommend to remember what was done with a computer or laptop before the error appears: Sometimes it is enough to load enough to disable the recently connected USB flash drive or an external hard drive, correct the SATA cable if you brushed the device From dust or something like that, just as simple.

Bug fix 1962 on laptop, monoblock or Lenovo PC

The first step to correct "Error 1962" - check the boot parameters to the BIOS / UEFI on your Lenovo.

Check the download parameters

Depending on the brand and the age of your computer, Lenovo, items in the menu can be slightly different, but the logic is saved everywhere. Points with "UEFI" in the names in the download parameters are related to the UEFI loading mode for Windows 10 and 8.1 (from the factory the system is set in this mode, but if you installed OS manually, you could do it in Legacy). If something remains incomprehensible, ask questions, I will try to answer.

1. In order to go to the BIOS on a laptop or monoblock Lenovo usually need to press F2. or Fn + F2. when turned on. On computers, depending on the model, either the same key or key can be used. DELETE (DEL).
2. Depending on the specific device model, the BIOS interface may differ slightly, but usually the tab with the parameters you need on Lenovo are called "Startup" (less often - boot), and you can go to it with the left-right arrow.

   

3. If on your device initially, Windows 10 or 8.1 was installed from the factory and you did not reinstall it manually, then set the parameters: CSM - Disabled (or on some models: Boot Mode - UEFI), just in case Switch Quick Boot in Disabled (Sometimes Helps), and then go to the PRIMARY BOOT SEQUENCE section and make sure that in the first place in the order of downloading is either Windows Boot Manager, or your system hard disk (you can move the steps + and - -). If there are some hard drives in the "EXCLUDED FROM BOOT ORDER" list, remove them from this list (select, press the "/" key), moving to the top list.

   

4. On Lenovo ThinkPad laptops, the same can look slightly otherwise (again, the description for the factory Windows 10 or 8.1): In the UEFI / Legacy Boot, select UEFI ONLY, in the Boot item to set the correct loading order. In the screenshot - just an example of download parameters on ThinkPad, and not correct settings.

   

5. If you installed the system manually, or you have been preset Windows 7, on the contrary, turn on the CSM (install in Enabled), on some laptops - enable boot mode to the Legacy Support or Legacy ONLY state, or on ThinkPad in the UEFI / Legacy Boot item set " Both ", and CSM Support - in YES, and then check the load order. The first in the queue should go a system hard disk (if there are several hard drives, also place them in Primary Boot Sequence, theoretically, the OS bootloader may be on them).
6. For systems different from Windows 10, 8 and 8.1, as well as for some assemblies and when an error occurs when loading from a flash drive, disconnect the Secure Boot on the "Security" tab.
7. Just in case, look at the Advanced tab in the BIOS and see the SATA MODE parameters. Usually, AHCI should be displayed here (with the exception of some systems, with pair SSD in RAID or with SSD caching).
8. Press F10, save the download settings and exit the BIOS, the computer will reboot.

If you do not know which options to set in the boot parameters, you can try the Legacy option and the UEFI option, without forgetting to check the devices in the order of download (usually on Lenovo PRIMARY BOOT SEQUENCE.

There is another method if you do not know which parameters to select, and the hardware configuration of the laptop or monoblock has not changed after purchase:

1. Click the "EXIT" tab to BIOS.
2. Look at the "Load Default Settings" items (download the default settings) and, if there is OS OPTIMIZED DEFAULTS (Parameters for the default operating system). If there are a second item, try downloading the options first for Oter OS, and then if the problem persists - for Windows 10 or 8 (depending on which item will be displayed, inherently they are the same).

Damaged Windows bootloader

The same error may be caused by a damaged system loader. On this topic there are separate instructions on the site:

• Windows 10 boot recovery
• Correction of boot records with BootRec
• Windows 7 boot recovery

If these items did not help, then it is possible that the case is in hardware issues.

Hardware problems that can cause ERROR 1962 on Lenovo

Hardware problems in the context of the error under consideration can be attributed:

• Poor hard disk or SSD connection. Check the connection for PC and some monoblocks (where the cable connection) is both from the motherboard and from the drive itself (and it is best to completely disable and connect anew). Often helps the replacement of the SATA cable.
• Faults of the disc itself, for example, after impact. If possible, check the disk performance on another computer. If faulty is likely to be replaced.

I hope one of the methods will help you correct the problem. If not, describe in detail the situation, all the actions performed and that preceded the appearance of an error in the comments, I will try to help.
