View Full Version : [ubuntu] Integrity check failed, multiple CD/versions - any ideas?

October 1st, 2008, 10:42 AM
A little bit embarassing as I haven't yet got past the first hurdle to install.

I am encountering a CD Integrity Check Failed message when checking the CD's that I have burnt, have tried all of the suggestions in a previous post in this forum and nothing is yet working.

Does anybody have an idea as to why this might be happening or have any suggestions for other ways I could install Ubuntu please?

Any troubleshooting tips welcomed.

brief history- - -
Have used two different CDROM burners with a variety of different branded media, new and old CD's to burn multiple copies of both the desktop and alternate install CD for 8.04. On each occasion the MD5 check passed after download from canonical servers and the CD check is being performed on both a Lenovo T61 laptop and a custom home desktop machine... It fails each time when checking 'restricted' files and though the filename is never the same 'nvidia' is mentioned somewhere 2/3 times. I have tried to ignore the errors and install to the laptop but failed with a pretty serious message about the integrity of a whole heap of different boot related files.

Thankyou for any help.

I assume you're on Windows?


Burn as slowly as possible. If the CD check fails, there's no chance your installation will turn into a success story.

Other than that, you can use Wubi to install Ubuntu like a windows application. I wouldn't recommend that method for a long term installation, but it'll do if you want to have a look.

You can also order a disk for free here:

Thanks for the suggestion, looks like I may have to request a CD if I can't get any of mine to work.
