I've been a good Ubuntu user since 11.4 on my 64bit Dell Inspiron N4010 laptop, and everytime installed with USB stick but this time, I can't install Ubuntu 12.10 on my laptop. I had this issue again but then the networking solution didn't work since 12.10, so everytime it happened I made an upgrade on my existing installation and it just worked. But now I can't fix it, because the USB live Ubuntu is not booting up and it hangs on the splash screen.

Here's the logs: https://www.dropbox.com/sh/isi0sgqma25iblu/DYU0L2UxU2

I thought it might be because of my swap partition, because on any mode on in the recovery menu(from friend recovery) it hanged on fsck, so I just removed my swap partition and removed the /etc/fstab entry for the swap. Not sure it was the right way, but it didn't change anything.

The USB works perfectly with a Dell Latitude E6500 laptop, even though I get the not a typewriter message.

As I researched the 'cannot mount to /dev/sr0, no medium found' is also ok.

Note that I don't want to remove all my partitions and make a clean install, that's gonna be my last resort.

Any keyboard shortcut won't after that. Up and down arrows that shows the splash screen won't work after it's hung. alt + ctrl + F1-7 won't do anything. Same goes to alt + ctrl + delete.

One more thing is that having persistent storage or not having it, wouldn't make any difference. I made the usb with dd but, same results obtained with unetbootin or pendrivelinux.

I cross posted this to ubuntu forums.

Did you try? Looks like ttys and networking are operational –  Grizly Feb 2 '13 at 21:32
    
Actually if I do that before, it gets hung it goes there, but it doesn't ask for my username. It gets hung after some time eventually and I can't go back to the main. –  Farid Nouri Neshat Feb 3 '13 at 1:50

This might be a stupid answer, but when the boot from usb starts, do you just leave it and wait for it to startup or do you press space untill a menu comes up ?

It's actually another question not an answer. :P I first go to boot menu to tell to boot from the USB and leave it like that. I don't know the the menu that you are talking about nor haven't pressed space. For the pictures I made, I went to the Ubuntu boot menu and removed the splash quiet options so I see all the logs. –  Farid Nouri Neshat Feb 2 '13 at 10:12
    
What I mean is, if the usb starts booting, there is first a purple screen with a white logo at the bottom, if you press space (or any other key I think), it will give you the options to try ubuntu or checkk disk for defects etc... When I usually select try ubuntu or install ubuntu from this menu, I don't get any errors. I've seen in the past on some of my live usb's that they load with errors however, pressing a key to open that menu and selecting the option from there usually works. –  Janpan Feb 3 '13 at 21:44
    
I know what you saying. No that didn't work. But thanks anyway :D –  Farid Nouri Neshat Feb 4 '13 at 5:13
