This question already has an answer here:

Brought a new Think Centre Edge 71 because

The Lenovo ThinkCentre Edge71 desktop has been awarded the status of Certified for Ubuntu.

Spent the the past 2 days trying to get any Ubuntu 12.04 64bit to install and boot. All give me the same answer:

Error 1962: No operating system found

Here are a few of the links I've tried:

Just installed Ubuntu 12.04. When booting, all I get is a black screen with cursor. Some of the links report to solve the problem. None have worked.

Is there a relative simple way to install and boot Ubuntu 12.04 64bit on a Think Centre Edge 71?? I mean it is Certified for Ubuntu?

Do you have EUFI BIOS? Maybe try traditional MBR setup... – fleamour Apr 4 '13 at 11:52
@fleamour I agree, if you want to stick to (U)EFI, make yourself familiar with (states >=12.04.2 64bit as minimal requirement) or consider 14.04.1 which is the current LTS version with reliable (U)EFI support. – Karl Richter Sep 10 '14 at 14:57

This worked for me on a thinkcenter.

Things to note are that,

sda7 in that example is where linux is installed.

root (hd0,0) -> 0 means the first partition on hard disk. For me the second partition sda2 had ubuntu. So I used (hd0,1).

Happy ubuntu guys.
