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.
But here is my Boot-repair log:
=> 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?
