I had to force a hardware reboot due to some CPU hungry application. It now hangs at the start-up screen right after the progress circle completes.

I have no way to see what it is doing (checking the FS or something) but when I press ctrl+alt+del, a s/w reboot occurs in 5 seconds.

How can I see the regular Linux start-up log instead of the splash screen and at least understand what it is doing.

use the dmesg your boot.log to troubleshoot the booting problem – Mughil Feb 10 '12 at 15:21

Boot your machine as you would normally and when prompted to, Press any key to enter the menu do so.

In the grub menu select the entry you want to boot then press e

Highlight the kernel line and press e

Navigate to the end of the line and remove rhgb quiet then press enter

Press b to boot your system.

You should now see the system messages as it boots.

The "escape" key normally switched to the boot-up message. – AndreasM Feb 10 '12 at 15:36
Thanks a lot, this would probably take me years to find out! – Nick Feb 10 '12 at 15:58
@AndreasM -- escape works, but as soon as the circle progress is done, it does not – Nick Feb 22 '12 at 8:19
@Iain Your solution make the system continue to boot up, but unfortunately the stuck later after starting atd service! Any addition? – SIFE Dec 26 '12 at 0:27
Turns out that selinux cause the problem, just adding selinux=0 to the end, and then pressing b make the system boot up. – SIFE Jan 18 '13 at 11:30
