Hardy ISO burn issue

[attercop]

I've downloaded the 8.04 iso and can't get it to burn to CD at all. I have checked the md5sum and it's just as it should be. I first burned it using my Ubuntu 7.10 and simply right clicking the iso etc. That CD was not recognised as any type of bootable media and startup went straight to GRUB.

I've checked in the BIOS and CD is #1 bootup, with HDD #2. I installed k3b and tried burning the same iso again. It again burned but k3b stopped responding at 50% when it was about to check the burn for errors. On reboot it did the same as the previous CD.

I booted into WinXP and using Nero tried to burn it again, but was not able, receiving a 'Write Error' each time.

What's going on?

Follow this guide:
https://help.ubuntu.com/community/BurningIsoHowto?highlight=%28burn%29%7C%28
Burn as 'image' not as 'data', at 4x or less. You cannot do it with Nero. Download ImgBurn: http://www.imgburn.com/index.php?act=download
Install. Go to Mode>ISO>Burn. Set speed at 1x or 4x

I have already followed the burn ISO image how-to and md5sum verify how-to guides. I installed ImgBurn and followed your instructions and that burn failed also (at 1x speed). I now have 3 identical coasters from three different burning programs.

I should add that i've burned many Linux CDs from ISO in the past, so it's not like i'm new to this. Is it possible that the ISO file is corrupt despite displaying the correct md5sum?

Maybe the culprit is your burner. clean the lens. Check CD integrity before install. Try your CD's in a different computer.

I burned the ISO image file onto a DVD-RW so i could chuck it onto another PC to burn it onto CD. It burned the DVD-RW without a problem, and it's been burning music CDs without issue recently. However when using the other CD burner on another PC to burn the 8.04 ISO it burned fine first time without defects. So it is indeed my burner having an issue.

Strange that it burns DVDs and music CDs fine but is struggling to burn an ISO image though. How does one clean the lens?

There are disks that you can buy in a Computer Supply Store that clean the lens. I you are more techie inclined you can just take it apart and use compressed air.
