I'm trying to boot an Ubuntu 14.04.1 LTS USB stick, and it seems it will never enter the Desktop.
I'm stuck on the bootscreen, and here are the lines when I press "ESC" :

umount: can't umount /cdrom: Device or resource busy
/init: line 7: can't open /dev/sr0: No medium found

It blocks a long while on "Scanning disc for index files...", then writes all the following and re-blocks on next Scanning disc for index files....
I used the usb-creator-gtk program to build my USB stick, with persistent data enabled.
As somebody seemed to have the same problem (http://www.reddit.com/r/linuxquestions/comments/2dsgd5/cant_boot_from_cdusb_to_install_ubuntu/) I tried the solution from there (adding nomodeset), but I still have the same results: blocked at the bootscreen (not really hanged because the little dots are still "alive")...
Does somebody have an idea what happens ?
