/dev/sr0 problem on USB

[gibbylinks]

How do you disable floppy's. Can that be done with a program in the GUI?

Disable floppy or. floppy controller in BIOS (if you don't have a floppy drive).

BIOS (Basic Input Output System - showing off now) is a small built-in program your PC runs when you boot it up. Normally you hold down a specific F-key on boot up to enter the BIOS. Although it can vary from manufacturer to manufacturer.

It's not a great idea to mess around in the BIOS unless you know what your doing.

Hi,

I think I have the same problem.
I booted Ubuntu from a 9.10 disk (the normal version from the ubuntu website).

From there I installed a Ubuntu system on a USB stick.

Started my via epia system from that stick. Everything worked kind of ok, but from time to time firefox and other application frooze and the machine did not respond anymore.

To solve those crash situations, I then installed all packages and patches, that were offered in the package manager.
After everything had been installed, I did a reboot ....

From now on the sytem could not start properly and I receive the /dev/sr0 error message.

Reformatted the usb disk, used latest unetbootin and created usb, now it works without any errors that I can see.


I have the same problem here but after the can't open /dev/sr0 error it drops to busybox shell and nothing happens after that.

The error is initramfs unable to find medium containing live file system.

When I type mount I see the usb drive is not mounted (no wonder there is no medium containing live cd ). I think I might be missing some kernel parameters at the boot menu, here is my boot menu entry for the live cd:

label ubuntu
menu label Ubuntu live
kernel /casper/vmlinuz
append  file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash --

Will now try without quiet and splash option but I don't see (of find any using google) option to tell it to run from usb instead of cd/dvd. Is there a list out there somewhere with valid kernel parameters? Can anyone who has this working post the entry in their syslinux.cfg?

try to remove this option

file=/cdrom/preseed/ubuntu.seed

and add this option

live-media-path=/casper/

and add this option (to prevent the boot from hanging with infinite "stdin: error 0" outputs)

ignore_uuid

full sample

kernel /casper/vmlinuz
append boot=casper initrd=/casper/initrd.lz live-media-path=/casper/ quiet splash ignore_uuid --

this work for me...

Excuse me, but i'm quite a noob. Where do i modify these parameters?

Thanks!

Normally in syslinux.cfg file, as written above, if it's simple USB with just Ubuntu.
In some other case, it's menu.lst with multiple entries and boot options.

Disable floppy or. floppy controler in BIOS (if you don't have a floppy drive).

Many Many Thanks. This worked for me straight away. The USB stick worked on many other computers but this one had no floppy in it. Got to the installer fine now

Cheers!!!

I had the same problem installing ubuntu 10.04 64bit and mythbuntu 10.04. This worked for me. THANKS!
