i installed ubuntu 12.04 on my win7. But now when i try to load ubuntu most of the time when the name "ubuntu" appears on the screen it will stuck. Then on my keyboard the lights except the num-lock light starts to blink. Then i restart my laptop it works. But my win7 has no problem. What i want to do?

I think restarting my laptop several times with the shutdown button cause problems in future. help me?

I am facing similar problem with my Ubuntu installation, and I think the problem is some of the hardware I have in my desktop is not fully supported by the kernel so in instants it goes to kernel panic and as result it just crashes.

Each distro tweak the kernel a little bit do accommodate their own personality so if it is behaving that way with Ubuntu perhaps it wont happen in Fedora or OpenSuse. I am seriously considering the switch to a different distro.

I had everything working in Ubuntu 10.04 but now 12.04 is very unstable in my computer.
Good luck to you.

This led blinking points to kernel panic. Is there a way to boot your ubuntu without the splash screen? This would help track down what is causing this behaviour.

@OP you would need to edit the grub entry so that there is only the root, kernel and initrd location entry (been a _long_ time since I have worked with grub). The boot will then start without a splash screen and you would be seeing where exactly the boot stops or there is a kernel error like pointed out.
Post the entry that causes thee boot to fail and we can take from there.
BTW is there an option of safe boot where you boot with minimal drivers? Also tell us wether the installation went without errors.

How can i edit the grub entry that lead to "boot start without a splash screen?"

When you see the grub - the boot options (the very irst thing you see on the screen when the computer bots up) you will find a list of boot options.
I think you have to press 'e' to edit the options. Look for the line that says 'kernel=' this is the boot parameters line . This line determines what parameters are passed when booting. This is the line that needs to be edited.
