view story

http://askubuntu.com – I just bought ASUS UX42VS and I am have troubles installing ubuntu 12.10. After booting from USB or CD, whatever I select in the grub menu, the screen goes black and the computer does nothing. I have already tried to edit grub settings with nospalsh noguiet nomodeset but it did not help. Can you please help? (HowTos)
