Hi Everyone,
I downloaded the CentOS 6 x86_64 DVD ISOs and burned the first image to a rewritable DVD. When I tried to boot my new home server off it, it didn't, and then this was printed to the screen:
ETCDisolinux: Found something at drive = EF No DEFAULT or UI configuration directive found! boot:
The same disc works fine in my 4 year old HP laptop, and when installing CentOS 6 as a KVM.
I've found one post from a Fedora 14 user that was having the exact same problem, but no one replied to him. Other articles, posts etc. around the net reference something different for the "EF" part.
Does anyone know what's going on? I've never seen this problem before.
Regards,
Ranbir

I had an smililar issue using the CentOS 6 DVD with a DVD-RW. The same install disk worked perfectly on another system. I ended up having to use the Netinstall CD to do the install.

This is often a side effect of what I have been told is a poor specification in the DVD industry regarding writing at > 1x speed, in that certain requirements were set for that speed but not for higher speeds.
I have had much better luck with DVD data portability if I always burn DVDs at 1x (or as close to it as the DVD firmware will allow), particularly when it comes to burning on one system and reading on another.

Hello Devin. I heard that about audio CD's as well. Some that are burnt on a PC at home will not play properly on a car CD player. The answer was to burn at a lower speed as possible.
I try to burn my data CD's and DVD iso's at a low speed as possible.

with newer hardware, decent quality blank media, and current generation '16X' and '20X' burners, I find burning DVDs at 8X, which is the max CLV speed, gives me a very high level of player compatibility. Better yet, it doesn't take hardly any longer than the 'full speed' burn. faster than 8X, the drives use CAV mode where the burn speed goes up on the outer part of the disk, which makes the last 20 or 25% of a full disk much more prone to errors.
btw, I've found current generation Samsung fullsized SATA & ATAPI(IDE) burners to be very reliable and highly compatible with a wide range of playback gear.

I used K3B in Fedora 15 to burn the DVD image. I changed the speed to 1x, but K3B reported the burn speed as 2.4x - I guess it couldn't go any lower.
The newly burnt image didn't boot either. The error was the same.
So sad. :(

A shot in the dark: my DVD image burned by K3B won't also boot. Using Brasero and all was fine. Not reproducable, but worth the attempt.

My successful burns (although not tried with CentOS 6 yet) have been using growisofs directly:
growisofs -speed=1 -dvd-compat -Z /dev/dvd=image.iso

Hi Ranbir.
Did you check the integrity of the downloaded iso image before burning it?
Can you try to burn the iso on different machine at a slow speed. See if it boot then?

The download is good. I made sure to do the checksum before burning the image.

I already tried that: it won't boot. :(

All 3 DVD-s (2 x x86_64 + i386) are burned on K3B 0.12.17 on CentOS 5.6.
x86_64 is tested and works. i386 not yet tested but it passed K3B verification.

Ok. But using K3B-2.0.2 didn't work here to produce a bootable CentOS ISO image.

Here, latest k3b on 5.6 did not like my DVD-Rs for some reason... could not even start burning. I used the 'CD/DVD Creator' and it worked. Only difference I could think of is that the slowest in k3b was 1x, while it was 0.4x in 'CD/DVD Creator'...

I was going to try that, but seeing as how a Fedora 15 x86_64 ISO burnt to the same rewritable DVD boots properly, I don't see how a DVD-R will resolve the CentOS problem.
I'll still try it. It's worth a shot.

Here's a silly thought: try shoving a CD/DVD cleaner disk in, the kind they sell for CD players.

Brasero and K3B both use growisofs and wodim on the backend. Burning DVD- is a different process from burning DVD+; substantially different at the physical media, and thus different bugs are exposed.
Jorg Schilling's own cdrecord utilities may work more reliably for DVD- burning (he says they should work better for all burning, but I haven't tested that). YMMV. Jorg is not as gracious about the differences and about the issue as I am being here; you can read it all for yourself and decide for yourself what to do about that.... but using his cdrecord suite is guaranteed to make your system not 100% upstream EL compatible.... at least in terms of those utilities.
I know a client of mine has had multiple problems with Brasero and certain brands of media, mostly DVD-, when I haven't had issues, but using DVD+ almost exclusively. I'm probably going to rip out wodim completely, and try out Jorg's mkisofs and cdrecord instead, and see if that fixes the problem. But I digress.
I downloaded the CentOS 6 x86_64 DVD ISOs and burned the first image to a rewritable DVD. When I tried to boot my new home server off it, it didn't, and then this was printed to the screen:
ETCDisolinux: Found something at drive = EF No DEFAULT or UI configuration directive found! boot:
The same disc works fine in my 4 year old HP laptop, and when installing CentOS 6 as a KVM.
By any chance is the drive that does not work *NOT* a CDRW drive? Sometimes CD-ROM drives do not like reading rewriteable media.

Can you read other discs burned by that burner in the server machine? I understand that it has a DVD/CD burner, but is a CDRW burner? Can you attach this drive to a USB cable or move it to the affected machine to see if the problem follows the drive or the machine?

The burner I'm using is a built in laptop drive. :/ However, I have used it to burn LinuxMCE DVD images, and those have always booted on my new machine without issue.
I think it's something specific to CentOS 6 and the particular hardware I'm using.

I've tried everything people have so kindly suggested - the DVD has failed to boot each and every time.
I decided to burn a Fedora 15 x86_64 DVD ISO to the same rewritable DVD I've been using for the CentOS 6 DVD image. I also used the same burner. The Fedora 15 DVD booted just fine.
So, what I can conclude is something is broken. :/

I have all of the SATA channels set to AHCI mode, which includes the Pioneer burner. I was thinking that maybe I should try changing the BIOS setting to IDE, but then tossed it aside as crazy talk.
After your email, I decided to change the DVDRW drive's SATA channel to IDE mode. Bingo! The CentOS 6 DVD booted. I have CentOS 6 running and fully updated now.
I haven't looked into why the SATA Pioneer DVDRW needed AHCI disabled in order to boot off the CentOS 6 DVD. Since the Fedora 15 DVD booted without issue, I can only surmise isolinux in CentOS 6 and in Fedora 15 behave differently.
Thanks to everyone that tried to help out. I appreciate everyone's efforts.

Hmm. I am facing an unrelated problem [1] but the root cause could be similar to your problem. I'll try changing SATA from "enhanced" to "legacy" mode.
[1] Linux Mint Debian Edition installs successfully, BIOS is able to see the hard drive but complaints there is no boot disk!

Hi again Ranbir. This reminds me of a similar problem I had on an older Advent laptop. The problem was due to bad BIOS calls in the firmware.
It was fixed by Mr HP Anvin, the maintainer of the ISO boot loader by writing a work around to dodge the wonky BIOS code.
http://en.wikipedia.org/wiki/SYSLINUX
Maybe you have a similar problem?
Does your machine hang with an error message during the boot process?
