Comment 9 for bug 262944

capnahab : Ok, did you try "mount -t vfat /dev/sdb1 /mnt/USB" or "mount -t vfat /dev/sda1 /mnt/USB"? Another way to list the devices would be this : ls /dev/sd* . However, if it still doesn't work, I don't know what would be possible, I think that there is no network at this point in the boot process.

Another thing that might be useful : If you know a (probably older) version of ubuntu that you are able to boot, you can provide the lspci log by typing this in a terminal "sudo lspci -nnvv > lspci-nnvv.log". (lspci-nnvv.log will be saved in the current directory of your terminal, generally /home/(username) .

Thanks for the time you take to help the improvement of ubuntu.
