How to capture boot sequence??

Hi, I have problem of booting Arch.
For some reason, after I select Arch Linux from GRUB, Arch force the computer to reboot and do it infinitely.
I have two operating systems on my box, Arch and Windows.
Window doesn't reboot my PC.
So i want to know if there is anyway to capture boot sequence lines in a text log file so that i can see what causing the rebooting.
Thanks!

Re: How to capture boot sequence??

Which log file would be the one that captures the startup sequence (the list of lines that shows up after you select arch from grub)?
Would it be kernel.log?
Hope that I guess it right..

I may be wrong, but | think you may have set the default runlevel to 6 in /etc/inittab. Runlevel 6 is the reboot runlevel.

When you bootup and get Grubs menu, type e, then use the down arrow on the keyboard to select the kernel in Grubs menu. Now type e again, and after one space add 3 to the kernel line. Press the "Enter" key, followed by typing a b.

If all's gone well, you should now be booted up into runlevel 3 on the command line with a prompt to login.

Login as root, and give your root password. Now type.
nano -w /etc/inittab

A few lines down you will see a line like:
id:3:initdefault:

That's my line above, as I'm still setting up Archlinux. If you see the line above showing as "id:6:initdefault", this will always reboot continuously when trying to boot the machine. You will need to change the 6 to a 5 if you want to boot up into KDE, Gnome,etc, or if you just want to boot up into text mode, change it to 3.

Hope you fix the problem.

dmesg gives you the output of what happened at boot, normally.

/var/log/messages.log would contain the boot messages.
You can try booting into single user mode and check the contents of the log.
