I have 12.04 Ubuntu on my notebook; but, I do have a problem with it. I cannot boot, if I don't press anything then there is a black screen, and it does not boot.

If I press the space button,or any other key,for multiple times, like 20 or 25 times, for example, then it's boot in seconds normally.

How can i resolve this?

Ps:I do not have a problem with BIOS as it's already booting on first for the hard drive.

Try adding pci=nomsi to the kernel parameters when it boots. This will be in the grub menu, or extlinux.

You can test it at the same time you choose between your kernels by manuall appending it to the start line.


just check your bios settings if the boot device priority is correctly set. Just try to check if the network is not the primary boot device or the CD-ROM device. Make the hard disk your first boot device and then check if that resolve your problem.
