Haven't been able to find an answer to this one anywhere on the internet. Yes, I've set BIOS to boot first from CD. The hard drive has nothing on it. I'm trying to install an OS from CD. Yes, the CD is bootable. I put it in another computer and it booted just fine. I have also taken the CD drive out and replaced it with another, same result. I get something to the effect of Error: 1962 no operating system found. I see the CD in BIOS, and the light on CD comes on. But will not boot from CD.
I think that Ztcoracat has found the cause of your 1962 error.
Several Lenovo models have this problem with the data/power cable from the hard drive.

I would love to try swapping the cables. Unfortunately, the B540 uses a proprietary SATA connection for the HDD; the data and power connections are all part of a single plastic connector, with the cables permanently attached. There is no way to use a standard SATA cable without breaking the power and data portions of the connector apart, which would undoubtedly void the warranty.

You are on to something there... in fact you hit the nail on the head…
1962 error is that cable!!!
I ran into that issue, and currently I'm (again). Error 1962. Now, I'm not using ubuntu (is my mom's pc), but since the issue is about the hardware, the OS doesn't make any difference. We bought the E1 thinkcentre on Jan/2013, 4 days after purchased the pc crashed. Lenovo exchange the HDD then but with w7 instead w8. A faulty lenovo technician tried install w8 but he failed and then for some reason the MOBO was damaged. Lenovo took the PC and 1 month and half later we got the PC back home with a new HDD and a new MOBO (according Lenovo). I powered up the pc and 4 hours later, guess what: 1962 again.
Using the logic, I thought, new HDD, new MOBO, should be the cable... or connectors, or definitely the MOBO.

Perhaps the CD is damaged. It has happened to me several times that my computer does not boot a CD, and its always because the CD is somehow damaged. Not visually or anything. Even CDs that work on other computers or is visible and looking fine inside the OS of the same computer.
Perhaps I left them in the sun or something. Not sure. But I had CDs working and booting that later did not and I had several burned CDs which never booted. Try to burn the CD image on a new CD again! I would recommend using K3b for burning the CD.

It looks like the 1962 error is the one that was found by one of the other posters, but some other things occurred to me.
If the hardware is old enough, the newer OSes won't boot. How old is old enough? It would depend on the combination you are using... (like someone else mentioned) - hardware and software.
The other thing I can think of, is the CD itself - some CD roms won't read some CD media, because they are too "see through" - ie the laser can't get enough reflected light to distinguish what is on the CD. I've had that issue on a couple of CD media I've used on older systems. I ended up re-burning the CD to a media that was less "see through" and this occasionally solved the issue... I haven't run into that problem on the later greater hardware I've got now, for a decade or so.

This seems to perhaps be related to my issues of some CDs booting on some machines and not on others.

Interesting.
I've had the same issue with a Ubuntu DVD/CD.
The DVD/CD would boot on a 4 year old Quad Core Desktop but wouldn't boot on a new Desktop that I just built from bare metal.
If it helps the older Desktop had the Legacy BIOS and the brand new Desktop has the UEFI BIOS.
I think that the laser that reads the CD is not the same laser that burns.
Another potential issue would be 'compliance'. Track to laser alignment due to wear of the mechanical system for the drive. If one drive that is used to create the ISO image has wear then the read on another drive that may have wear will just compound the issue thus not reading the track. I wonder if the OP tested the written image on the same system that created the CD and had a valid boot. But when moved to another system then the compliance due to wear will prevent boot due to alignment because the read laser cannot continue on track due to a shift.

I wonder, could the laser be dirty?
Hi Ztoracat,
UEFI and BIOS refer only to the means that are used to boot from the hard drive.
Backwards and forwards compatibility of newer OSes and newer chipsets are not always a must.... I'm guessing that Intel/AMD have made a lot of changes to the code they expect to see at boot time. I'm glad that the attempts at using some of the older or newer media burns doesn't seem to cause self destructive behaviour - now *that* would be a real problem!

If one wishes to boot a DVD/CD then the secure boot must be disabled. This firmware does allow booting a DVD/CD via disabled secure boot. If not then how do you propose that Microsoft or any other OS upgrades or modifies a install? Look here; http://www.uefi.org/

FWIW I had secure boot disabled on the new machine and the DVD/CD still would not boot.
I think it was a key issue.
For some reason only certain distribution's (Ubuntu, Linux Mint and Fedora) of a Live CD's will boot.
