Error 1962 no operating system found linux

Error 1962: no operating system found after installing 12.04 (Lenovo ThinkCentre)

I just installed a fresh copy of Ubuntu 12.04 on a new Lenovo ThinkCenter from a USB drive. When I restarted after installation, the boot sequence didn’t find the OS. Instead I got the no operating system found error. When I started Ubuntu from the USB, I could see the HDD and that it had all the installed files. I just couldn’t boot into it. It appeared that GRUB was not at the right place or that there was something wrong with the UEFI and GRUB. What is the simplest way to fix these errors?

Just remove the bootable pen drive at the right time when after successful installation when the ubuntu prompts to restart. Also select the device while booting and then install.

I had the same problem on a Lenovo ThinkCentre M92p (Tiny). Make sure you set the bootable USB up by first formatting, then partitioning, then dd’ing the img file. I didn’t partition, just formatted. It installed, but notably didn’t mention where to install. Then it had this 1962 no operating system found problem. By starting again and partitioning the usb properly first, it worked. I found out by installing an earlier version to see if I got the same error (so an earlier Ubuntu version may also be an approach).

Ok. this took a lot longer than it should. But here it goes:

Installing 12.04 on a 64 bit system that supports UEFI booting like the thinkcentere will create three partitions on the system: a FAT partition for EFI, the ext4 partition for ubuntu and some swap. However, restarting the machine, I was not able to boot at all. Initially, the Intel Boot agent would kick in and try to boot from the network. Even if you turn that off, as indicated later, it still doesn’t boot. It says no operating system found.

Now here are the things I tried that didn’t work for me:

1. Change the SATA controller type to IDE Using a boot repair disk (it doesn’t know how to handle EFI with GPT partitioning)
2. Changing the order of the boot sequence to put HDD first
3. Changing the boot mode from UEFI, to Legacy or to Auto
4. Recompiling GRUB2 and putting it in the UEFI paritition, as indicated here:https://help.ubuntu.com/community/UEFIBooting

The first good direction I got was from this thread:http://ubuntuforums.org/showthread.php?t=1896052 People were having problems with earlier versions of Ubuntu. One of the suggested solutions is to install 10.04 first, and update from there.

What this really does is forget UEFI altogether, and create just two partions..the ext4 for ubuntu 10.04 and swap. You could then upgrade to ubuntu, which keeps the same partitioning. A couple things to note. mind your architectures, since this particular machines support 64 bit or 32 bit, so the 10.04 you install first should have the architecture you intend to keep. Also, your network card will likely not work on the 10.04 kernel, so you will have to upgrade from the cd by installing the alternate iso. Follow these instructions: https://help.ubuntu.com/community/PreciseUpgrades#Upgrading_Using_the_Alternate_CD.2BAC8-DVD .

What I did instead was, First installed 10.04, then install ubuntu 12.04 again, but go to ‘do something else’ on the partitioning page. and i simply chose to reformat the main ubuntu parition and leave the swap as is (mind you, after 10.04 you probably have only those two partions on the HDD you installed the ubuntu on). [in retrospect, I could just have created those partions without installing 10.04, it seems]

Once installation is done, I restarted, but was greeted with an error «invalid arch independent ELF magic». Looking this up indicated that grub was probably from a previous version of ubuntu,and needs to be installed again. I had to boot from the liveCD/USB again, and reinstall grub2 (you can follow these steps:https://help.ubuntu.com/community/Grub2/Installing#Reinstall_from_the_LiveCD)

Alright, now restart again. It should boot, but I got some errors at the begining which said «no suitable mode found» and «no graphics mode found». Apparently, this is something simple that has to do with fonts. Found this bug report https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/699802 and then used the workaround on comment #24 and viola. Now the system boots into 12.04 with no errors. it is using legacy booting. but it working for now at least.

I believe this can be fixed in the installation process of 12.04, but things are this way for now.

Unexpected: Error 1962: no operating system found.

Am running 16.04 on a older Lenovo ThinkCenter.
Have had no real issues until now.

Suddenly when starting the computer after it was shutdown for 5 days, I get the Error 1962: no operating system found.
Have been now been playing around a bit with
— UEFI/Legacy mode
— boot repair
— exchanging the SSD drive to another one and installing 18.04

but I get nowhere, still error 1962

any support highly appreciated!

Ubuntu addict and loving it

Re: Unexpected: Error 1962: no operating system found.

Hello, that error message is probably specific to the Lenovo family of machines.
Here are two links for possible solutions.

Hopefully the first one will fix it, at least for a while. If not use the second link.

Here hopefully you can swap cables around.

Re: Unexpected: Error 1962: no operating system found.

Hi,
Thanks for helping out.
Unfortunate non of those actions worked. Still same error.

I tried to put in the original HD with windows, changed BIOS to legacy boot, and windows booted.
So the problem seems to be connected to: lenovo+UEFI+linux.

As I only will have linux on the HD, my plan now is to a new installation (18.04) with legacy boot (so adding the 1 MB boot partition).
or I get deeper with UEFI and see if I get get the boot to work. I had similar problem with another lenovo computer some time ago. Just have forgotten how I solved it back then.

Re: Unexpected: Error 1962: no operating system found.

I was dealing with the same issue several months ago. Have you tried changing boot options? I think that it was the one that helped me. Also, as I read in this guide, running Windows diagnostic tool or enabling System Restore Point can help.

The appearances of ‘no operating system found’ error while using PC is a clear indication that your PC is contaminated with a System malware. Well, need not to be panic because there is an expert solution through which you can easily resolve such an issue. Visit — https://www.removemalwarevirus.com/d. -malware-virus

Re: Unexpected: Error 1962: no operating system found.

Doubt if malware.
No operating system found, is almost always wrong boot mode. You have UEFI with Secure Boot, UEFI and CSM/Legacy/BIOS as choices and if system boot mode does not match install, it gives that type of error.
