I installed Ubuntu 12.04 on my notebook but I can't boot. The status is a black screen and no key works.

Strangely, I can boot the Ubuntu as a next method:

  • Plug USB stick (install program)

  • Boot sequence changes (HDD → USB)

  • USB lamp blinks and stops

  • Booting from HDD

Why can't I boot without USB stick?

Do you have Windows installed? If so, how did you install Ubuntu? Need more details. – apesa May 8 '12 at 14:57
    
No. I didn't install Windows. I just installed ubuntu from the live cd(usb stick). – batman May 10 '12 at 13:23
    
I solved. :) I installed auto mode for many times. but, I did not still able to boot.. so, i installed manual mode(partition settings) and was able to boot!! i don't know why..(ubuntu bug????) :( – batman May 10 '12 at 13:32

Sounds like you have your bootloader installed on the USB-stick.

When either boot into ubuntu with the boot stick and reinstall grub to the correct partition/drive or reinstall ubuntu making sure to point the installer to the correct partion/drive in the step where you configure your partition setup. You may have to go into the customize menu to do this.

youll want something like:

sudo grub-install /dev/sdx

where sdx is your primary partition on the drive your bios tries to boot

I assume your getting that error when your try to run grub-install? what is your sdx? sda? – madmaze May 9 '12 at 8:55
    
I execute "sudo grub-install /dev/sda". but, I solved it like above comment of question. but, I don't know why. :( . anyway, thank you so much. – batman May 10 '12 at 13:35
