I recently tried to replace Windows with Ubuntu 14.04 on an SSD. Somehow after installation I could not boot into the system. It said:

ERROR 1962 - NO OPERATING SYSTEM FOUND - PLEASE PRESS ANY KEY TO REPEAT BOOT SEQUENCE

Since my machine (A Lenovo ThinkCenter K410) uses UEFI, I used a EFI boot partition for EFI bootloaders, used the SSD for the system, and the original HDD as the data drive. What's weird is that it doesn't boot right after installation, but it boots after I use boot-repair to fix it. But when it restarts, it fails to boot and gives me the error code as above.

I did somehow run into a post regarding this problem and it indicated it was a Lenovo bug.

ERROR CODE 1962 - NO OPERATING SYSTEM FOUND - Lenovo Community

But here is my Boot-repair log:

Ubuntu pastebin

It said:

 => Grub2 (v1.99-2.00) is installed in the MBR of /dev/sdb and looks at sector 
17672192 of the same hard drive for core.img, but core.img can not be 
found at this location.

So is that the problem instead of the Lenovo bug? If so, how should I fix this?

Thanks!

On UEFI Hardware you have to install Ubuntu in UEFI Mode.

So When you boot on your installation drive you should see a black screen with grub to launch the live session :

UEFI Mode

And not the :

Not UEFI Mode

Try with to boot from your bios on your usb drive with uefi.

To check if your are in the right mode in the live session you can try :

[ -d /sys/firmware/efi ] && echo "Mode EFI" || echo "Mode classic"

Before installing Ubuntu I recommend to go to gparted to re-create the partitions needed for UEFI.

You might need to allocate at the beginning of your drive a partition for the bios (something like 5mo). And directly after you should have an efi partition who look like : Size : between 100Mo and 250Mo; Type : FAT32; Other : Flag "boot".

Now you can install Ubuntu via the graphical install and Ubuntu should detect the efi partition and install at the end the grub efi version.

I hope this solve your problems.

Yes, I tried to install it in EFI mode and yes it boots for the first time, but fails whenever after. And it boots every time right after I fix it with boot repair but not if I reboot again. It is weird I know. –  Kevin Hu May 18 at 16:46
    
Could you check if grub is installed on your internal drive or on your usb drive ? –  Romain Fluttaz May 19 at 21:57
