I have an external CD drive which connects to USB. I burned 11.10 Ubuntu image to CD-R. The disk correctly shows me install page when I autoload disk within Windows 7.

When I restart to attempt to boot from disk to install Ubuntu I get the following error for a split second before I continues to boot to Windows.

"isolinux.bin is missing or corrupt".

Clearly my computer knows that this is a Linux disk in the usb cd-drive...What went wrong?

edit: I reburned another disk, same error

Perhaps... you should listen to your Computer when it tells you that the CD you made is corrupt. Use another one, A CD-RW would be better if not, then a USB stick. – Uri Herrera Feb 14 '12 at 23:01
I agree, most likely a bad burn. You should also check the iso - – bodhi.zazen Feb 14 '12 at 23:14
I reburned another disk, same error! Any ideas? – Display Name Feb 14 '12 at 23:58
Download the ISO again and check the MD5 check sum – Uri Herrera Feb 15 '12 at 1:52
OMG ppl, it's not the case. Checking MD5 sums advice is everywhere. But checksums are the same. Still can't boot into such image. – marines Sep 23 '12 at 15:15

You should First check the MD5sum Before write to CD or USB. In your case The .iso you downloaded and burned on disc is faulty. You have to download .iso file again.

Like everyone said probably a bad burn.

I recommend using a tool called Unetbootin which makes your pendrive bootable.

It is way faster then using a CD.

I don't have a pendrive with me that has enough space for the Image. I reburned the disk and the error is there still, any idea? – Display Name Feb 14 '12 at 23:59
bad burn or a bad dvd/cd drive .... any 1 GB pendrive will do... or you can try an Ubuntu minimal iso thats only 26 mb u can use anoter program to burn – sarveshlad Feb 16 '12 at 1:07
