initial boot from usb of ubuntu 10.10 destop ends with error "initranfs unable to find a medium containing a live file system" A cat of casper.log shows the error is line 7 on init which cannot find dev/sr0.

Asked by Gary Williams

The first boot of my usb ubuntu 10.10 brings up the start page and then after several minutes crashes with "initranfs" stating that it is unable to find a medium containing a live file system". If you cat casper.log it reports a failure of line 7 of init which tries to use a dev/sr0 which doesn't exist.
The only other problem to this point is that in creating the usb via windows, my avira virus protector rejected running my usb:\autorun.inf, which I assumed was OK at this point.

Any help would be appreciated.

Did you MD5 test the ISO you downloaded/
If you burned a CD, did you burn it as slowly as possible and did you use the "Check for defects" tool once initially booted to?

Many thanks for your responses.

1. I was trying Ubuntu 10.10 via USB.
2. I have proved that the md5sum on the iso image is correct.

The USB boots. I get the new Ubuntu page with the heartbeats until the crash message as previously stated.
Once it crashes I have just the basic OS commands to use and these hang all to easily and require a reboot.

I'm still reading potential USB issues, but much is mentioned about previous releases, little so far on 10.10.

I will also try the live CD/DVD method, but USB is my preferred method for this.

Any further assistance would be very welcome.

Alas I'm unfortunately I'm not alone with this Ubuntu 10.10 USB booting problem.

   Linked to bug: #543875
   https://bugs.edge.launchpad.net/bugs/543875
   "unable to find a medium containing a live file system"

I have now managed to run Ubuntu 10.10 after creating a liveCD.

I'm not going to chase the USB fix here, but it is required for the product.

Sorry, but I thought I'd already replied some time ago stating that I had
created a bootable CD and now successfully use Ubuntu. There continue to be
many issues with using a bootable USB, their various types, drivers, boot
options/conditions etc requiring all potential users to examine. The Ubuntu
help should give the user the potential problems before wasting so much time
on the USB option.
I have moved on to the next major problem, how to print using a Canon
printer without a supported driver (MP620). As I investigate this, I find
that printing is a huge area of many peoples angst. Ubuntu is great, I'm
loving its simplicity and speed, but equally still having to resolve the
printing. Ubuntu has some way to go until its ready for non technical usage
i.e the normal user.

Yes, printing is the worst issue in Ubuntu, because there are such many printer models (needed to sell such many costly cartridge). And programmers can't do reverse engineering of all printers.
Please, could you mark question "solved".

Many thanks for your assitance. I cannot contribute further and will signoff this problem as solved. I appreciate there are remaining USB boot issues, but these are already covered under other bugs.
